Medical Review: Dr. Gerald Mastaw, MD – Board-Certified Physician Last Updated: October 2025
Understanding the Science of Aging
Aging is a gradual, lifelong process that begins earlier than most realize often as early as your 20s. Over time, every organ and tissue experiences cellular wear and reduced regenerative capacity. These microscopic changes can influence how we feel, look, and function.
While aging cannot be stopped, scientific advances in regenerative medicine are exploring ways to help the body age more gracefully, supporting recovery, vitality, and overall well-being.
How Aging Affects the Body
Common age-related concerns include:
Changes in vision or hearing
Persistent fatigue or low energy
Fine lines, wrinkles, or thinning skin
Muscle loss and joint stiffness
Sleep disruption and slower recovery
Memory lapses or brain fog
Bladder or bowel changes
These symptoms often occur simultaneously, reflecting cellular aging—when cells lose efficiency in repair, energy production, and immune balance.
Traditional Approaches to Age Management
Most conventional age-management strategies address individual symptoms rather than underlying biological aging. Common options include:
Medications: for joint discomfort, sleep, mood, or hormone support
Cosmetic treatments: fillers, Botox®, or resurfacing to enhance appearance
Lifestyle changes: diet, exercise, stress reduction, and quality sleep
Hormone therapy: when clinically indicated
Supplements: vitamins, antioxidants, or collagen to maintain general wellness
While these methods can help manage effects of aging, they typically do not address cellular regeneration or tissue repair.
A Modern Regenerative Approach
Regenerative medicine, including stem cell and exosome-based research, is an emerging field focused on supporting the body’s natural healing mechanisms.
Why Stem Cells Are Being Studied
Stem cells are unique because they can:
Differentiate into specialized cell types
Release growth factors and exosomes that encourage tissue repair
Help modulate immune responses
Support healthier function in muscles, skin, and organs
Important: Stem cell therapy for age management is experimental and not FDA-approved. Current research focuses on safety, dosing, and long-term effects. Any use should be discussed with a qualified physician experienced in regenerative medicine.
Recent Human Studies on Umbilical Cord MSCs and Exosomes

Spinal Cord Injury and Its Link to Chronic Pain
A spinal cord injury can have long-lasting effects on your body, impacting movement, sensation, and daily activities. Chronic pain often becomes a persistent challenge for those living with SCI, affecting quality of life.
What Happens in a Spinal Cord Injury
A spinal cord injury (SCI) disrupts communication between the brain and the body. The spinal cord serves as a critical network that transmits signals controlling movement, sensation, and organ function. When this pathway is damaged, signals may be blocked or misdirected. Patients often experience numbness, weakness, or loss of coordination depending on the injury location. Traumatic events such as motor vehicle accidents, falls, or acts of violence are common causes of SCI.
Types of Spinal Cord Injuries (Complete vs. Incomplete)
Complete injuries cause total loss of sensation and function below the injury site, while incomplete injuries leave some signals intact. For example, a complete cervical injury may result in paralysis of both arms and legs, affecting your ability to perform basic tasks. In contrast, an incomplete thoracic injury may allow partial movement or sensation, letting patients retain some independence in daily activities. Injury classification also influences potential treatment outcomes and how rehabilitation and therapies, including stem cell approaches, may support recovery.
Why Chronic Pain Develops After SCI
Chronic pain develops because damaged nerves send abnormal signals to the brain. After an injury, nerve fibers may misfire, creating ongoing pain sensations even in the absence of an external trigger. In addition, muscle spasms, stiffness, and localized inflammation can worsen discomfort. Individuals with SCI report chronic neuropathic or musculoskeletal pain, underscoring the need for supportive interventions to manage symptoms and improve daily function.
Stem Cell Therapy for Spinal Cord Injury: An Overview
Stem cells for the treatment of spinal cord injury are an option that targets the damaged areas of the spinal cord to improve function and reduce chronic pain. This therapy is designed for patients who already have a confirmed spinal cord injury diagnosis and are exploring regenerative approaches to support recovery.
What Stem Cell Treatment for Spinal Cord Injury Means
Stem cell therapy for spinal cord injury uses regenerative cells to support repair processes in damaged tissue. These cells work by modulating inflammation, helping damaged nerve tissue survive, and supporting the activity of neural cells. Introducing regenerative cells into injured areas may reduce muscle spasms, improve motor function, and promote better communication between the brain and body.
Types of Cells Studied for SCI (Mesenchymal Stem Cells and Neural Cells)
Two cell types often studied in stem cells for the treatment of spinal cord injury are mesenchymal stem cells (MSCs) and neural cells.
Mesenchymal stem cells (MSCs) release growth factors that regulate inflammation and support tissue repair. In patients with spinal cord injury, MSCs have been observed to reduce swelling around damaged nerves and support partial recovery of muscle function. Clinical observations suggest that MSC therapy can lead to measurable improvements in the motor function of patients, depending on the location and severity of the injury.
Neural cells contribute to nerve pathway repair and enhance communication between the spinal cord and brain. By supporting damaged neurons and promoting nerve signaling, neural cells may improve voluntary movement and reduce chronic pain. Early studies indicate that introducing neural cells in injured spinal regions can aid in reestablishing motor and sensory pathways in cases of incomplete injuries.
How Stem Cells May Help Manage Chronic Pain in SCI Patients
Chronic pain after a spinal cord injury affects multiple aspects of your daily life, from mobility to sleep and overall comfort. Stem cell therapy for spinal cord injury offers potential pathways to address these challenges by targeting the underlying cellular processes involved in pain and tissue repair.
Reducing Inflammation and Muscle Spasms
Stem cells may help calm inflammation that contributes to pain and spasticity. Mesenchymal stem cells (MSCs) used in stem cell treatment for spinal cord injury release signaling molecules called cytokines that influence immune activity around damaged nerves. These molecules can lower nerve hyperactivity and ease continuous muscle tension. Patients receiving MSC therapy often report noticeable reductions in spasticity and localized inflammation within weeks of treatment, contributing to less discomfort during movement and rest.
Supporting Nerve Repair and Neural Cell Activity
Stem cells may aid in nerve protection and regeneration. Both MSCs and neural cells in stem cell therapy for spinal cord injury can support damaged neurons, helping them survive and re-establish connections. Improved neuronal connectivity can restore signal transmission between the brain and affected regions of the body. Even partial recovery of nerve function can lead to measurable improvements in motor control and a reduction in neuropathic pain.
Improving Circulation and Motor Function
Stem cells may promote better blood flow to injured tissues. Enhanced circulation helps deliver oxygen and nutrients to areas affected by spinal cord injury, which may decrease discomfort and support voluntary movement. Patients with incomplete injuries often experience improved coordination and mobility after receiving stem cell treatment for spinal cord injury, with some reporting measurable gains in range of motion and functional independence.
Enhancing Muscle Strength and Daily Function
Stem cell treatment may help reduce muscle wasting and weakness. Strengthening muscles that have weakened due to spinal cord injury can decrease the risk of secondary pain caused by compensatory movements. Patients receiving stem cell therapy for spinal cord injury have reported increased control over previously weakened muscles, less stiffness, and greater ease in performing daily tasks such as standing, reaching, or transferring from a wheelchair.

Autoimmune diseases are a group of complex conditions in which the immune system mistakenly attacks the body’s own tissues. Examples include Crohn’s disease, systemic lupus erythematosus, rheumatoid arthritis, scleroderma, and psoriasis. These diseases are chronic and often progressive, affecting multiple organs and causing long-term damage. Patients with autoimmune diseases experience inflammation and tissue injury that can lead to permanent organ dysfunction. Current treatments, including anti-inflammatory drugs, immunosuppressants, and biologic therapies, aim to control symptoms and prevent disease progression. However, these treatments often fall short, sometimes failing to maintain remission or causing significant side effects over time.
The limitations of existing therapies have prompted researchers to explore alternative strategies, and stem cell therapy has emerged as a promising option.
This study analyzes trends and challenges in clinical trials of stem cell therapy for autoimmune diseases.
Understanding Autoimmune Diseases
Autoimmune diseases vary widely in their clinical presentation and the parts of the body they affect. For example, rheumatoid arthritis primarily targets joints, leading to chronic pain and swelling, while scleroderma involves fibrosis and vascular problems that affect the skin and internal organs. Inflammatory bowel diseases, such as Crohn’s disease and ulcerative colitis, result from impaired intestinal barrier function and abnormal immune responses in the gut. Systemic lupus erythematosus involves the production of autoantibodies that deposit in multiple organs, causing inflammation and tissue damage. Psoriasis affects the skin through immune cell interactions that drive excessive inflammation. Globally, autoimmune diseases impact over one billion people, with rising rates in developing countries due to environmental changes, lifestyle factors, and better diagnostic capabilities.
Treating autoimmune diseases typically requires balancing immediate symptom relief with long-term disease management. Anti-inflammatory drugs and glucocorticoids help control acute symptoms, while immunosuppressants and biologics maintain disease remission. Newer therapies, including small-molecule inhibitors targeting specific immune pathways like JAK-STAT, have been developed for patients who do not respond to conventional treatments. Despite these advances, significant challenges remain. Long-term use of medications can cause side effects such as metabolic syndrome, increased infection risk, or cardiovascular complications. Existing therapies often suppress immune responses but cannot reverse tissue damage or fibrosis, leaving patients at risk of permanent organ impairment even after symptoms improve.
The Role of Stem Cells in Autoimmune Disease Treatment
Stem cell therapy offers an innovative approach to address the limitations of traditional treatments. Different types of stem cells are being studied for their ability to modulate the immune system and repair damaged tissues. Mesenchymal stem cells, or MSCs, are among the most researched due to their immunomodulatory and regenerative properties. MSCs secrete molecules like TGF-β, prostaglandin E2, and IDO, along with exosomes containing regulatory microRNAs, which help suppress overactive immune responses while promoting regulatory immune cells that maintain balance. MSCs can also migrate to inflamed tissues and differentiate into functional cells, directly contributing to tissue repair.
Hematopoietic stem cell transplantation, or HSCT, works differently. It involves high-dose immunosuppression to remove the faulty immune system, followed by the reintroduction of stem cells to rebuild immune tolerance. HSCT has shown long-term remission potential in diseases such as scleroderma and multiple sclerosis. Induced pluripotent stem cells, or iPSCs, can be engineered to produce specific immune-regulating cells or to regenerate damaged tissues, offering precise treatment options for autoimmune conditions.
Despite these promising approaches, stem cell therapy faces challenges in clinical translation. Personalized treatments, including autologous iPSC preparation or selection of allogeneic MSCs, are complex and costly. Standardizing procedures for cell culture, differentiation, and quality control increases costs. Additionally, long-term safety data are limited, particularly regarding immune reactions to allogeneic cells. Thorough research and standardized protocols are needed to ensure that stem cell therapy can be widely adopted safely and effectively.
Trends in Stem Cell Clinical Trials for Autoimmune Diseases
Recent analyses of global clinical trial data from 2006 to 2025 provide insights into the current landscape of stem cell therapy for autoimmune diseases. Out of more than 1,500 trials, 244 met strict inclusion criteria for detailed analysis. Most trials are in early stages, with 83.6% in Phase I or Phase II. Crohn’s disease, systemic lupus erythematosus, and scleroderma are the most frequently studied conditions, highlighting high clinical interest in these diseases. The United States and China lead in the number of trials, reflecting strong governmental and institutional support for stem cell research. Academic institutions fund nearly half of the studies, though collaboration with industry remains limited, which may slow the translation of research findings into clinical practice.
The trials focus on key therapeutic strategies, including immune modulation, tissue repair, and suppression of overactive cell proliferation. Disease-specific differences in cell sources and delivery methods are evident. MSCs are the predominant stem cell type used, largely due to their strong immunoregulatory properties, safety, and allogeneic use. HSCT is applied in severe or refractory cases, while pluripotent stem cells like iPSCs are less common due to ethical concerns, tumor risk, and the need for directed differentiation.
Challenges in Clinical Translation
A major barrier to stem cell therapy is the variability in cell preparation. Differences in cell source, harvesting techniques, expansion protocols, and quality control can impact treatment outcomes. For example, MSCs derived from bone marrow, adipose tissue, or umbilical cord each have distinct properties and applications. Standardizing cell preparation and testing, including assessing cell viability, potency, and safety, is critical to improving consistency across studies.
Financial and logistical challenges also limit the widespread use of stem cell therapies. Autologous treatments are expensive and labor-intensive, while allogeneic therapies require careful immunological matching to prevent rejection. Regulatory hurdles add further complexity, as safety and efficacy must be thoroughly demonstrated before treatments can become mainstream. Long-term follow-up studies are particularly important for evaluating the durability of treatment effects and for monitoring potential adverse events.
Advances in Targeted Therapies and Delivery Methods
Clinical trials have explored novel targets and delivery strategies to enhance the effectiveness of stem cell therapy. Immune targets like CD19 and CD52 are used in therapies that aim to selectively deplete pathogenic immune cells, while growth factors secreted by stem cells support tissue repair. The routes of administration vary based on disease and cell type. MSCs are often delivered intravenously for systemic immune modulation, whereas localized injections are used for tissue repair. HSCT is uniformly administered intravenously, and epithelial stem cells are transplanted directly to target tissues. Emerging technologies, such as MSCs combined with drug-loaded nanoparticles or injectable hydrogels, are being developed to extend therapeutic effects and reduce the frequency of treatments.
Clinical Outcomes and Effectiveness
Stem cell therapies have demonstrated promising results in several autoimmune diseases. In systemic lupus erythematosus, allogeneic MSCs have induced complete or partial remission in roughly half of patients with refractory disease. HSCT in SLE and scleroderma shows long-term disease modification, with improvements in organ function and symptom relief. In Crohn’s disease, local MSC injections have achieved high rates of fistula healing, whereas HSCT offers limited benefits due to its associated risks. Rheumatoid arthritis studies have shown short-term improvements in patients who have failed conventional therapies, indicating the potential of MSC therapy as an alternative treatment for refractory cases.
The source of stem cells can influence treatment outcomes. Umbilical cord-derived MSCs are particularly useful in systemic lupus erythematosus due to their immunomodulatory potential and ability to differentiate into multiple cell types. Bone marrow- and adipose-derived MSCs are commonly used for localized tissue repair, such as in Crohn’s disease. Ongoing research aims to refine stem cell selection, identify subpopulations with optimal therapeutic effects, and develop precision therapies tailored to individual patients.
Future Directions in Stem Cell Therapy
The future of stem cell therapy in autoimmune diseases lies in technological innovation, international collaboration, and precision medicine. Advances in gene editing, such as CRISPR-Cas9, allow for enhanced stem cell function and tracking, while multi-omics analyses can help identify the most effective cell subpopulations. Establishing stem cell banks, similar to Japan’s iPSC Bank, can address limitations of autologous stem cells and facilitate wider access. Precision medicine approaches, including biomarker-based patient stratification, real-time monitoring of treatment response, and integration of genetic and microbiome data, can help tailor therapies to individual needs. Large-scale, multicenter clinical studies and real-world data collection will be crucial for assessing the safety and effectiveness of stem cell therapies.
Combining stem cell therapy with other treatments, improving delivery methods, and targeting multiple pathways simultaneously may further enhance outcomes. For example, MSCs combined with drug-loaded nanoparticles or hydrogels can provide sustained anti-inflammatory effects, while engineered stem cells can selectively regulate immune responses and repair damaged tissues. By integrating these strategies, future therapies may offer safer, more effective, and cost-efficient options for patients with autoimmune diseases.
Implications for Clinical Practice and Future Research
Stem cell therapy represents a promising frontier in the treatment of autoimmune diseases. Clinical trials indicate significant potential for conditions such as Crohn’s disease, systemic lupus erythematosus, and scleroderma, though most studies are still in early stages. Current therapies focus on immune regulation, tissue repair, and the suppression of overactive cells, but challenges such as high costs, limited long-term safety data, and variability in cell preparation persist. Technological innovation, global collaboration, and precision medicine will be essential to overcome these challenges. With continued research and clinical development, stem cell therapy has the potential to provide patients with safer, more effective, and individualized treatment options that go beyond symptom management to address the underlying mechanisms of autoimmune disease.

You won’t find exaggerated claims or comparisons here, just realistic, patient-focused information backed by experience. We customize each treatment plan using the documentation you provide, and we support you throughout your journey. This article will walk you through the basics of spinal cord injury, explain how stem cells for the treatment of spinal cord injury are used, and outline what to expect with our process.
What is Spinal Cord Injury?
A spinal cord injury (SCI) is damage to the spinal cord that disrupts communication between the brain and the body. When this pathway is damaged, the body’s ability to send and receive signals becomes impaired. That can mean a loss of movement, sensation, or automatic functions like bladder and bowel control. Most spinal cord injuries happen because of sudden trauma. Studies show that the most common causes of SCI were automobile crashes (31.5%) and falls (25.3%), followed by gunshot wounds (10.4%), motorcycle crashes (6.8%), diving incidents (4.7%), and medical/surgical complications (4.3%).
The spinal cord does not regenerate the way some tissues in the body do. This makes the injury permanent in many cases. The outcome depends on where the injury occurred and how much of the nerve pathway is still intact.
Types and Locations of Spinal Cord Injuries
Spinal cord injury (SCI) is classified by severity, complete or incomplete, and by the spinal region affected. A complete injury results in loss of all movement and sensation below the injury site, while incomplete injuries allow some function. The spinal region involved guides recovery and therapy goals.
Cervical nerve injuries (C1–C8) impact the neck, arms, hands, and breathing, with higher levels possibly requiring ventilation support. Thoracic injuries (T1–T12) affect chest and abdominal muscles, impacting balance and trunk control. Lumbar and sacral injuries (L1–S5) influence leg movement and bladder function, with outcomes varying based on injury extent and completeness.
Common Symptoms and Challenges After SCI
Patients with SCI may experience paralysis, sensory loss, chronic pain, and complications in daily functions. Spinal cord injury affects more than movement. Many patients deal with muscle spasticity, pressure injuries due to immobility, frequent urinary tract infections, and problems with body temperature control. Autonomic dysreflexia, a sudden increase in blood pressure triggered by stimuli below the injury level, is a serious risk in those with injuries at or above T6. Emotional and psychological responses, including anxiety and depression, are also common and require support.
At Stemedix, we recognize that each spinal cord injury is unique. We tailor every treatment plan based on the medical records and information you provide, not generalized assumptions. If you’re exploring stem cells for the treatment of spinal cord injury, our team is ready to walk you through options that align with your health history and functional goals.
What is Regenerative Medicine?
Regenerative medicine supports the body’s repair mechanisms by introducing biologically active materials. This field focuses on helping your body respond to damage by using living cells and biological components. Instead of masking symptoms, regenerative treatments aim to influence the cellular environment that surrounds the injured tissue. In many cases, this includes the use of stem cells and growth factors.
For individuals with a spinal cord injury, regenerative medicine introduces new options that may encourage healing responses the body struggles to activate on its own. While this type of therapy doesn’t replace rehabilitation, it may work alongside your current efforts to promote tissue stability and reduce secondary complications.
Stem Cell Therapy as a Treatment Option for SCI
Stem cell therapy for spinal cord injury is being explored to support recovery and symptom relief. Researchers are investigating how stem cells may influence the biological environment of an injured spinal cord. You won’t find a generalized approach here. Stem cell treatment for spinal cord injury is tailored to each case based on the location of injury, severity, and medical history.
The focus is not on reversing the damage or offering a cure. Instead, stem cells for the treatment of spinal cord injury may help by releasing chemical signals that support the health of nearby nerve cells, protect against further breakdown, and potentially stimulate limited repair processes. Some patients have reported improvements in muscle control, sensation, or bladder regulation, though outcomes vary and remain under study.
How Stem Cells Work to Support Healing
Stem cells can develop into specialized cell types and secrete proteins that support tissue repair. These cells have two key roles in regenerative medicine. First, they can adapt to different cell types, such as those found in the nervous system. Second, and equally important, they release helpful proteins, like cytokines and growth factors, that create a healing-friendly environment. This may reduce chronic inflammation and improve communication between nerve cells that remain intact.
In spinal cord injury cases, these cells may influence glial scar formation, improve blood flow to the damaged region, and protect vulnerable cells from oxidative stress. For example, studies have shown that transplanted mesenchymal stem cells can release brain-derived neurotrophic factor (BDNF), which plays a role in supporting neural survival.
At Stemedix, we offer regenerative therapy based on the existing diagnosis and medical documentation provided by each patient. Our approach respects the experimental nature of this therapy while offering guidance and structure throughout the process.
Potential Benefits of Stem Cell Therapy for Spinal Cord Injury
Exploring the potential benefits of stem cell therapy gives you a chance to learn how regenerative medicine may support certain aspects of your spinal cord injury recovery. While results vary for each individual, many patients report improvements in pain, movement, and physical function over time.
Pain Reduction and Muscle Relaxation
Many patients report decreased neuropathic pain and reduced muscle tension following therapy. Neuropathic pain is one of the most common and challenging symptoms following spinal cord injury. You may experience burning, tingling, or shooting sensations due to misfiring nerves. For some individuals receiving stem cell therapy for spinal cord injury, these symptoms become less intense or more manageable. This could be related to how certain types of stem cells interact with immune cells and inflammatory pathways.
Studies have suggested that mesenchymal stem cells (MSCs), for example, can release bioactive molecules that influence the environment surrounding injured nerves and even interact with neural cells in spine and brain conditions. In some cases, patients also describe less spasticity or tightness in the muscles, which can reduce discomfort during sleep or daily movement.
Improved Circulation and Motor Function
Stem cell treatment for spinal cord injury may support vascular health and contribute to smoother movement. Reduced blood flow after a spinal cord injury can limit your body’s ability to heal or respond to therapy. You might notice cold extremities, swelling, or slower wound healing. Stem cell therapy may support microvascular repair by promoting angiogenesis, the formation of new blood vessels in damaged tissues. This improved circulation helps deliver oxygen and nutrients more efficiently to the affected areas. Some individuals receiving stem cell therapy report smoother joint movement, greater control over posture, and better balance during transfer or mobility tasks.
Increased Muscle Strength and Abilities
Muscle engagement and strength may increase as nerve signals improve. After a spinal cord injury, the connection between your brain and muscles may be disrupted or weakened. Over time, this can lead to muscle wasting or limited control. For individuals receiving stem cell treatment for spinal cord injury, some report noticeable changes in muscle tone, voluntary movement, or strength, especially in the lower limbs or core. These observations tend to occur in cases where some nerve pathways remain intact.
For example, a patient with an incomplete thoracic injury might regain the ability to perform assisted standing exercises or show improvements in hip stability. While not every case leads to increased muscle output, any gains in strength can contribute to mobility training, sitting tolerance, and daily activities.
Patient Experience and Reported Outcomes
Individuals receiving therapy frequently describe improvements in mobility, energy levels, and daily activity. Each patient arrives with unique goals. Some hope to walk again. Others want to reduce fatigue or rely less on medications. After therapy, individuals often share changes that impact their quality of life, such as being able to transfer with less assistance, participate in treatment longer, or sleep more comfortably.
At Stemedix, we focus on your specific history, symptoms, and expectations before building a treatment plan. These outcomes help us communicate realistic possibilities, while always making it clear that regenerative medicine is still considered experimental.

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive lung disease that causes irreversible damage to the alveoli and leads to pulmonary interstitial fibrosis. Patients with IPF often experience severe difficulty breathing, which can result in respiratory failure and death. The disease is challenging to diagnose, has a high mortality rate, and a median survival of only three to five years after diagnosis, which is worse than many forms of cancer.
Current treatments primarily focus on supportive care, such as lung transplantation, mechanical ventilation, and oxygen therapy. Drugs like pirfenidone and nintedanib can slow disease progression but do not repair damaged lung tissue. For this reason, researchers are exploring the use of mesenchymal stem cells (MSCs) as a potential new therapy for IPF. MSCs are multipotent stem cells capable of self-renewal, differentiation, and secreting a variety of factors that may reduce inflammation, promote tissue repair, and regulate immune responses.
As part of this review, Li et al. summarize recent studies on MSCs in reducing lung inflammation and fibrosis, highlighting their potential mechanisms, such as migration and differentiation, secretion of soluble factors and extracellular vesicles, and regulation of endogenous repair processes.
Pathological Changes in IPF
The main pathological features of IPF include widespread alveolar damage, excessive proliferation of fibroblasts, and deposition of extracellular matrix (ECM) proteins. Fibroblastic foci, areas of active fibroblast and myofibroblast accumulation, are a hallmark of the disease and strongly correlate with patient outcomes. Fibroblasts in these foci arise from three primary mechanisms: proliferation of resident fibroblasts, epithelial-mesenchymal transition (EMT), and bone marrow-derived fibrocytes.
Resident fibroblasts proliferate and differentiate into myofibroblasts under the influence of factors like transforming growth factor-β (TGF-β). Myofibroblasts produce collagen and other ECM proteins, which contribute to tissue stiffness and fibrosis. EMT occurs when alveolar epithelial cells lose epithelial markers and acquire mesenchymal traits, becoming fibroblast-like cells that contribute to ECM deposition. TGF-β is a key driver of EMT, acting through pathways such as Ras/ERK/MAPK signaling. Endothelial cells can also undergo a similar transition, producing collagen and contributing to fibrosis. Bone marrow-derived fibrocytes, circulating in the blood, migrate to damaged lung tissue and differentiate into fibroblasts. Their accumulation is linked to poor prognosis and is guided by chemokine signaling pathways like CXCL12/CXCR4 and CCL3/CCR5.
Properties of Mesenchymal Stem Cells
MSCs, first discovered in 1968, are multipotent cells that can differentiate into bone, cartilage, and fat. They can be sourced from bone marrow, adipose tissue, and umbilical cord blood, and are identified by fibroblast-like shape, plastic adherence, and surface markers (CD44, CD29, CD90) while lacking hematopoietic markers (CD45).
MSCs have low immunogenicity, can modulate the immune system, and support tissue repair. Transplantation in animal models of lung injury shows promise with minimal side effects, but human safety and efficacy remain uncertain due to species differences and small clinical trials. Potential risks include tumor formation and unwanted angiogenesis, especially in immunocompromised patients.
Mobilizing endogenous MSCs is also being studied, as these cells can migrate to injured tissue, secrete reparative factors, and aid repair, with agents like G-CSF enhancing mobilization, though outcomes vary.
Mechanisms of MSC Therapy in Pulmonary Fibrosis
Mesenchymal stem cells (MSCs) help repair lung injury through multiple, interconnected mechanisms: migration to injury sites, differentiation, secretion of bioactive factors, immune modulation, and regulation of lung defenses.
MSCs are guided to damaged lung areas by chemokines such as stromal cell-derived factor-1 (SDF-1) and interleukin-8 (CXCL8). Once at the injury site, they can differentiate into type II alveolar epithelial cells, supporting tissue repair. This differentiation is influenced by Wnt signaling pathways, though in some cases, MSCs may become fibroblast-like cells, which could worsen fibrosis.
A key part of MSC therapy is the secretome, a collection of soluble factors. Growth factors like KGF, HGF, EGF, Ang-1, and VEGF restore alveolar and endothelial function, maintain lung barrier integrity, and reduce fluid buildup. Anti-inflammatory molecules such as IL-1ra, IL-10, PGE2, and TSG-6 help control inflammation and promote repair. MSCs also encourage macrophages to shift from a pro-inflammatory (M1) to an anti-inflammatory (M2) state, aiding recovery. Early administration during acute inflammation provides the most benefit.
MSCs exert immunomodulatory effects by secreting chemokines, adhesion molecules, and regulatory factors like nitric oxide (NO) and indoleamine-2,3-dioxygenase (IDO), which suppress T-cell activity. They influence B cells and support regulatory T cells to maintain immune balance. MSCs can also secrete TGF-β, which can either aid healing or promote fibrosis depending on context and timing.
Extracellular vesicles (EVs), including exosomes and microvesicles, are another way MSCs deliver therapeutic benefits. They carry proteins, RNAs, and other molecules that reduce inflammation and promote tissue repair. EV-based therapy may offer many of the benefits of MSCs while minimizing risks associated with cell transplantation.
Finally, MSCs regulate molecules involved in oxidative stress, inflammation, and tissue repair. They decrease pro-fibrotic and inflammatory signals like matrix metalloproteinases and TGF-β1 while increasing antioxidant enzymes and repair-promoting proteins such as FoxM1, stanniocalcin, and Miro1, all of which protect lung tissue and combat fibrosis.
Advancing MSC Therapy for Pulmonary Fibrosis
Mesenchymal stem cell therapy represents a promising approach for treating idiopathic pulmonary fibrosis. Its benefits involve multiple mechanisms, including homing to injured tissue, differentiation, secretion of growth factors and cytokines, immunomodulation, and enhancement of endogenous lung defenses. MSCs are most effective when administered early in the inflammatory phase of lung injury, highlighting the importance of timing. Despite encouraging preclinical and early clinical results, safety and efficacy in humans remain under investigation, and some contradictory findings underscore the complexity of MSC therapy.
Li et al. conclude that future research should focus on optimizing MSC mobilization, improving therapeutic efficacy, exploring the role of microRNAs, and advancing clinical trials to establish MSC-based therapies as viable treatments for IPF.
