For millions of people across the globe, orthopedic issues cause discomfort, limited mobility, and other frustrating symptoms which make it challenging to participate in daily activities. Osteoarthritis, for example, affects the joints by wearing away the cushiony cartilage between bones. While the prevalence of the condition is on the rise, conventional treatments are still lacking: patients are often required to choose between temporary fixes such as medications to mask the pain or invasive surgical procedures. And, this isn’t isolated to osteoarthritis; patients with other orthopedic issues face similar dilemmas. For those suffering, there are several benefits of stem cell therapy for orthopedic issues.
This treatment involves the targeted administration of stem cells, which can self-renew and transform into virtually any cell type in the body. Researchers believe they hold tremendous healing potential for orthopedic issues due to their abilities to change into cartilage cells, minimize inflammation, and release cytokines to reduce pain and slow the degenerative process.
Below, discover some of the benefits of stem cell therapy for orthopedic issues, as well as the types of conditions they can treat.
Common Orthopedic Conditions Treated with Stem Cell Therapy
The potential applications for stem cell therapy span far and wide. Not only have they been used to treat orthopedic conditions, but they’re also used for patients with neurodegenerative and autoimmune conditions.
Some of the specific orthopedic issues being treated by stem cell therapy include:
· Osteoarthritis
· Sports and athletic injuries
· Musculoskeletal injuries
· Spinal cord injuries
· Degenerative disc disease
Benefits of Stem Cell Therapy for Orthopedic Issues
There are many advantages to stem cell therapy. Here are just a few of the most noteworthy benefits to consider:
· Reduced pain and inflammation
· The ability to delay or prevent the need for invasive surgery
· Increased healing potential
· An all-natural treatment
· Safe and effective
Finally, but perhaps most importantly, this regenerative therapy can give new hope to patients who haven’t seen results from other treatment methods. Stem cell treatment could help to restore mobility, alleviate pain, reduce inflammation, and enhance overall quality of life — outcomes which may have previously seemed unattainable to patients with orthopedic issues.

Over the past few years, data has accumulated showing the promise for cell-based therapies to help in treating Inflammatory bowel disease with stem cells. Specifically, stem cells appear to offer the opportunity to overcome several weaknesses associated with conventional therapies that have targeted perianal Crohn’s disease.
Based on these positive results, scientists and healthcare providers have become more adamant about understanding the broader role stem cells could play in the treatment of all inflammatory bowel disease. A new review published in Current Gastroenterology Reports discusses this specific issue and offers insights into the direction of stem cell research as it relates to inflammatory bowel disease.
The authors of this review discuss data from over a dozen clinical trials that have already been conducted on the impact of stem cell therapies in Crohn’s disease. Thus far, much of the success of regenerative medicine for the treatment of Crohn’s disease has been for the specific treatment of perianal Crohn’s disease, which occurs when the digestive and gastrointestinal inflammation associated with Crohn’s disease extends to the anal area.
Given the frequency with which the lining of the intestine is inflamed in inflammatory bowel disease, including both perianal Crohn’s disease and non-perianal Crohn’s disease, research efforts are focusing more and more on how stem cells may be able to combat this type of luminal disease. The authors put forth suggestions for the types of information that researchers should aim to obtain if we are to adequately treat intraluminal disease with regenerative medicine.
The potential of stem cells to address inflammatory bowel disease that has been demonstrated so far provides hope that this type of strategy will help not only patients with perianal Crohn’s disease but those with other forms of inflammatory bowel disease as well. More research should help to determine if and how these therapies can be deployed to help this patient population.

Researchers have recently established that a hallmark of Amyotrophic Lateral Sclerosis (ALS) is endothelial cell degeneration that leads to vascular pathology. When this vascular pathology occurs, damage develops to the barrier between the blood and the central nervous system. Given this new understanding of the pathophysiology of ALS, researchers have begun looking at the potential of repairing this barrier as a strategy for treating the disease with bone marrow stem cells.
A recent study, published in Scientific Reports, addressed this issue by testing how human bone marrow cells may impact blood-spinal cord barrier repair by transplanting these cells in an ALS model. The researchers hypothesized that the cells should help to repair the barrier, reversing the damage accompanying ALS. They were also interested in whether this type of repair may improve not only the integrity of the barrier between the blood and central nervous system but also improve symptoms of ALS.
What the researchers found was that the human bone marrow cells differentiated into the type of endothelial cells that were needed for repair and successfully engrafted into the capillaries of the spinal cord in their model. Several specific observations led the scientists to conclude that these stem cells helped to effectively restore the barrier between the blood and the spinal cord.
The stem cells improved the integrity and survival of nervous system cells, including astrocytes and spinal cord motor neurons, preventing problematic changes in these cells that are associated with the breakdown of the blood-central nervous system barrier. Critically, the implantation of the stem cells also led to improvements in behaviors associated with ALS.
While there is still a lot of research to be done to establish whether bone marrow stem cells can help repair the blood-spinal cord barrier in patients with ALS, this study provides promising data. Given that there is no cure for ALS and limited treatment options, there is likely to be an emphasis on cell-based therapies for the disease. As more data become available, we will get a clearer picture as to if and how stem cells can help ALS patients.

Crohn’s disease, a form of chronic inflammatory bowel disease, affects an estimated 700,000 people in the United States, affecting men and women equally. While the disease is characterized by abnormal inflammation in the gastrointestinal and digestive tracts, some people with the illness develop perianal Crohn’s disease. In this case, the inflammation extends to areas around the anus. The precise proportion of Crohn’s disease patients who develop perianal Crohn’s disease is debated, but the need for better treatments for the condition is not. A new and unique treatment is the use of stem cells to treat Perianal Crohn’s Disease.
Unfortunately, though there are several drug and surgical interventions that have been developed to treat perianal Crohn’s disease, each of the available treatment options suffers critical limitations, including risks for adverse side effects. There is no available therapeutic approach that successfully achieves long-term remission.
Based on the need for – and lack of – more efficacious interventions for perianal Crohn’s disease and the ability of cell-based therapies to address similar types of disease, researchers have positioned that stem cell therapy may be a promising avenue for the relevant patient population. A recent review published in the Journal of Crohn’s and Colitis covers the research that has been conducted to address this possibility and the data that suggest that mesenchymal stem cells could provide a safe and effective way to treat perianal Crohn’s disease without the unwanted side effects associated with conventional treatment options.
In this review, the authors cover clinical trials on cell-based therapies for perianal Crohn’s disease, including phase 1, phase 2, and phase 3 randomized controlled trials. The authors consider the differences in outcomes between conventional treatments and cell-based therapies and offer suggestions for the direction of research into the use of stem cells for the treatment of perianal Crohn’s disease.

Osteoporosis is a disease in which bones become weak, brittle, and are prone to fracture. While osteoporosis is commonly considered a disease of low bone density, it is more complex and extensive than that. New bone is constantly formed and destroyed (resorbed) throughout life. In osteoporosis, however, the rate at which it is resorbed accelerates, while the rate at which it is formed slows down. In other words, bone is being destroyed faster than it can be formed. This process changes the size and shape of bones and alters its microarchitecture (i.e. the structure of bone on a microscopic level).
Without screening, most people will not know that they have osteoporosis until they have a bone fracture. Bones simply get weaker until some minor trauma causes one or more bones to break. Fortunately, efforts to screen for the disease (e.g. DXA/DEXA or bone density scans) have helped doctors diagnose cases of osteoporosis before the disease progresses to the point of bone fracture.
The main treatment for osteoporosis is a class of drugs called bisphosphonates. Bisphosphonates block the cells that resorb bone (osteoclasts) to allow the cells that form new bone (osteoblasts) to catch up. While bisphosphonates are effective, many patients experience severe GI side effects from these drugs including reflux, esophagitis, and ulcers, and cannot take them.
In an effort to find new ways to treat osteoporosis and help patients who cannot tolerate bisphosphonates, researchers are exploring the possibility of using stem cells to treat the disease. Ideally, one would take stem cells from patients to help regrow bone. What has been unclear was whether a person with osteoporosis still has enough healthy stem cells to effectively regrow bone.
To test this, Dr. Jiang and colleagues collected stem cells from the fat tissue of patients with osteoporosis (i.e. adipose-derived stem cells). The researchers took these stem cells and encouraged them to grow and multiply for 14 days. After the stem cells had proliferated, they injected the cells into mice and studied the effects on bone growth. After 4 weeks, the researchers saw evidence on X-ray scans that adipose-derived stem cells caused new bone growth.
These results demonstrate that even patients with osteoporosis still possess stem cells that can be used to treat their own osteoporosis. While the stem cells need to be treated in a laboratory setting for 14 days, it is potentially possible to use a patient’s own stem cells to regrow bone and treat their osteoporosis.
The next phase of research will be to conduct a clinical trial to show test whether autologous stem cell treatment (injecting a patient with their own stem cells) can regrow bone in humans. While those clinical studies will be critical in determining whether this approach is practical and effective for patients, this laboratory research is very promising.
