Multiple sclerosis (MS) is an autoimmune condition in which the immune system attacks the protective sheath covering nerve fibers, known as the myelin. As a result, communication issues between the brain and other parts of the body occur. While there are currently several medications that can treat MS, some have serious side effects and may eventually stop working. So we ask ourselves ” How can stem cells help Multiple Sclerosis? ”
Recently, stem cell therapy has emerged as a new potential treatment option for people with relapsing-remitting MS (RRMS). In this version of the disease, symptoms may subside and then reappear in what’s known as a relapse. Eventually, RRMS can develop into a different form of MS in which symptoms stop subsiding.
Stem Cell Therapy for MS
Stem cells have the unique ability to transform into virtually any other differentiated cell type in the body. There are different stem cell therapy options in the field of Regenerative Medicine today. For instance, one is using hematopoietic stem cells that can differentiate into blood cells. In certain circumstances, doctors may use hematopoietic stem cell transplantation (HSCT) to treat RRMS.
First, doctors prescribe medication to increase the production of bone marrow stem cells. They then take some blood and reserve the stem cells for later use. Next, they prescribe strong medications, including chemotherapy, to suppress the immune system. Patients will require monitoring during this period of weakened immunity, and may therefore require a prolonged hospital stay.
Thereafter, the stem cells will be injected into the bloodstream to form new white blood cells and create an entirely new immune system. Until your immune system is functioning fully and independently, you’ll receive medications such as antibiotics to fight off illnesses or infections.
The treatment can take weeks, and recovery may take several months. Each individual is different, but many see a return to normal immune system functioning within six months.
Is Stem Cell Therapy a Potential Option for MS?
MS is a chronic disease for which there is currently no full cure, but results of stem cell therapy clinical trials are promising. In one, 69% of people had no relapse of MS symptoms or new brain lesions five years after receiving the treatment.
As with any treatment, it’s important to consider the risks involved with HSCT as well. For this therapy in particular, the risks of immune system suppression can be considerable. Nonetheless, for people with highly inflammatory RRMS with serious relapses and progressing symptoms, the risk/benefit ratio may be worth reviewing. Other studies are also showing potential for those with Multiple Sclerosis that how shown to be safe and effective.

In adulthood, cartilage has almost no regenerative potential. Cartilage damaged by disease, injury, or simply as part of the aging process can therefore not be replaced by the body on its own. As a result, bones may eventually rub against one another, resulting in pain and arthritis, a condition at least a fifth of all U.S. adults experience. So is it possible to regrow cartilage?
Recently, however, researchers from the Stanford University School of Medicine have discovered a means to regrow cartilage by manipulating stem cells, the body’s natural repair kit, and the foundation upon which all specialized cell types are developed. Specifically, the researchers found that using microfracture, or minimal injuries in the joint, can prompt the development of articular cartilage, the special type of tissue that provides a cushion between the joints. During microfracture, tiny holes are drilled into the joint to stimulate the healing process.
Traditionally, microfracture would create a substance called fibrocartilage, which more closely resembled scar tissue than cartilage. It wouldn’t behave the same as articular cartilage and would degrade quickly. By manipulating the microfracture process, however, they could direct new tissue to reach the cartilage stage.
First, they used a specific molecule known as bone morphogenetic protein 2 (BMP2) to trigger bone formation after microfracture. To prevent the regenerated tissue from becoming bone, they’d then stop the process using a different signaling molecule, vascular endothelial growth factor (VEGF). Both BMP2 and VEGF have been used for other clinical applications and are already considered safe and effective by the FDA.
As of yet, the studies have only been performed on animals. Eventually, researchers plan to move onto larger animals and larger joints. Once the treatment is ready for human clinical trials, researchers believe smaller joints will be the first focus; for instance, people with arthritis in the fingers and toes may be among the first to receive the treatment.
While this regenerative process holds promise, it likely won’t be available for several years. Moreover, researchers speculate that it may be most effective as a preventive treatment, or for patients in the earliest stages of cartilage loss. Fortunately, patients who already have considerable joint damage can consider other regenerative treatments, including stem cell therapy, to help alleviate pain and inflammation.

According to the CDC, in 2019, traumatic brain injury (TBI) contributed to nearly 61,000 deaths in the United States alone[1]. While there are several clinical treatments designed to address the neurological dysfunction after sustaining a TBI, including hyperbaric oxygen, brain stimulation, and behavioral therapy, none appear to produce satisfactory or lasting results.
In recent years, several studies have demonstrated the therapeutic potential of various stem cells, including mesenchymal stem cells (MSCs), neural stem cells (NSCs), Multipotent adult progenitor cells (MAPCs), and endothelial progenitor cells (EPCs) in the treatment of neurological impairment resulting from TBI. Specific benefits of these stem cells observed throughout these studies demonstrate that exogenous stem cells have the ability to migrate to the site of damaged brain tissue, help to repair damaged tissue, and significantly improve neurological function.
In this article, Zhou et al. review recent findings on the role, effects, deficiencies, and related mechanisms of the various stem cells being used as therapeutic agents in the treatment of TBI.
Examining numerous studies occurring between 2010-17 and exploring various TBI models and the roles of different stem cells in animal models, the author’s general summary is that the use of stem cells demonstrated some form of measurable improvement in every study reviewed. As a reference, specific observed benefits included improved integrity of the blood-brain barrier; improved neurological function, social interaction, and motor performance; enhanced neurovascular repair and recovery; and enhanced cognitive and spatial learning, information retention, and memory retrieval.
The authors point out that although there appears to be a large amount of research exploring the complexity of pathophysiology and the application of stem cell therapy for treating TBI, many problems still exist and must be addressed before the best method for TBI recovery can be determined.
Specifically, while there have been several clinical studies exploring the role of stem cells in the role of TBI treatment and recovery, and while most demonstrate promising results, the studies have almost universally been completed on mice and/or rats, contained human sample sizes that are not large enough, or failed to include a control group. As a result, Zhou et al. call for further study, including multi-center long term follow-up and randomized prospective trials that examine the safety of stem cells, route of injection, the time of injection, and the specific mechanisms as a way to identify the appropriate and effective stem-cell-based therapeutic treatment options for those suffering from various types of TBI.

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, is a rare disease in which the body’s neurons that control voluntary muscles begin to degenerate. Patients experience muscle weakening and involuntary spasticity, as well as symptoms such as muscle cramps and stiffness, and eventually, difficulty moving, speaking, swallowing, and breathing.
While there is currently no cure for the devastating illness, there are drugs that can increase the quality of life and marginally slow the disease’s progression. Researchers have long been pursuing a more effective treatment for the disease, and efforts were increased significantly as a result of the 2014 viral Ice Bucket Challenge, which raised at least $115 million for research efforts.
Stem Cell Therapy for ALS
One area that’s of particular interest to researchers is regenerative medicine therapy. Also known as stem cell therapy, this option could be a potential treatment for ALS, as it could help sustain and nurture motor neurons that have been compromised by the disease. This is due to stem cells’ ability to release neurotrophic factors, which support and protect nerve cells. This is not a cure, nor a guarantee, but is an option to help slow down the progression of the condition.
Stem cells can be harvested from sources such as the umbilical cord (Wharton’s Jelly), or the patient’s own adipose (fat) tissue, then strategically transplanted at locations such as the spinal canal, intravenous, or muscle tissue. Once in the brain tissues, stem cells have the potential to protect healthy neurons and replace those that have been compromised.
Experts are using stem cells both for research purposes, by creating cells genetically identical to patients to see how they’ll respond to treatments, as well as for treating patients directly. With their protective qualities, the cells can help preserve healthy cells and repair or replace those that have been damaged.
According to results from clinical trials, 87% of patients who received the treatment responded to the treatment with at least 25% improvement and slowed disease progression. Evidence also suggests the treatment is safe and well-tolerated.
While much of how ALS develops remains a mystery, researchers are hopeful that further investigation into stem cell therapy will help to drastically improve treatment outcomes compared to the drugs currently available. If you would like to learn more contact a care coordinator today!

Research exploring the benefits of mesenchymal stem cells (MSCs) has demonstrated tremendous potential as a regenerative therapy option for the musculoskeletal system. Research into these cell-based regenerative therapies is promising, and they must continue to provide the data necessary to show their therapeutic potential in clinical settings.
In this review, Steinert et al. review and summarize some of the promising and unique therapeutic features of adult MSCs, detail their current state of clinical application as a regenerative musculoskeletal therapy, and describe the potential for future developments in this field.
Specifically, as a part of this review, the authors share the status of 31 clinical cell therapies for musculoskeletal regeneration occurring between 1996 through 2011 and specifically covering bone defects and nonunions, avascular necrosis of the hip, cysts and benign tumors of the bone, cartilage lesions, and tendons and ligaments; results for the majority demonstrate the safety of and/or the efficacy associated with the specific method of cell-delivery being evaluated.
The field of regenerative orthopedics points to the large body of MSC clinical research indicating the successful treatment of myocardial infarction, post-stroke or spinal cord injury nerve regeneration, graft versus host disease, and a variety of other conditions as an indication that the application has tremendous potential as a regenerative therapeutic option in a wide variety of musculoskeletal indications.
Although there appears to be evidence demonstrating the paracrine and trophic functions of MSCs, research explaining the specifically demonstrated therapeutic effects is still being determined. The authors highlight that research continues to explore the reasonable therapeutic expectations associated with MSC-based treatments, an essential step required to fully understand the range of healing associated with musculoskeletal regenerative cell-based therapy.
The authors, in concluding this review, point out that the demand for MSC-based musculoskeletal regenerative therapies continues to increase. Steinert et al. call for further study into the specific combination of cell preparation, bioactive factors, and stimuli for each specific MSC therapeutic application. Once these have been demonstrated for each application and should they demonstrate better or improved outcomes compared to standard treatments, only then can they be considered for long-term clinical application.

In neurodegenerative conditions and cases of brain damage such as traumatic brain injury (TBI), the goal of treatment is usually to manage symptoms and prevent or slow the rate of further damage. Yet, ongoing research suggests stem cells could play an important role in creating new neurons, potentially resulting in repair of central nervous system damage and potentially regrow brain tissue. While the science is still in its infancy, there is evidence to suggest stem cell therapy could help to potentially restore lost brain function.
Just until a couple decades ago, scientists were under the impression that the brain and spinal cord could not rebuild themselves once cells were lost. Yet, in the mid-1990s, neuroscientists discovered that the brain could create new neurons in certain circumstances, which arise from neural stem cells. As undifferentiated cells, the stem cells could give rise to many different brain cell types, including neurons, which carry messages throughout the nervous system.
Further research has supported the idea that neurons can regenerate. For instance, in 2003, research was published which showed improvements in paralyzed rats who were exposed to a virus which caused symptoms similar to that of amyotrophic lateral sclerosis (ALS). Mice that had been previously paralyzed were able to regain some mobility after receiving stem cell injections, and the stem cells took on the characteristics of mature motor neurons.
Researchers have also been exploring stem cell therapies to help treat Parkinson’s disease. The goal is to rebuild the central nervous system through stem cell implantation. While levodopa is the go-to treatment to help regulate dopamine levels which are affected in PD, the drug’s efficacy tends to wear off over time, and its side effects increase. Some researchers have investigated the use of fetal stem cell tissue for PD patients, but lack of standardization and challenges in acquiring donor tissue have been barriers to ongoing research efforts.
With that said, stem cells from umbilical cord blood and adult adipose (fat) or bone marrow can also be coaxed to display many protein markers similar to those found in nervous system cells. It’s unclear whether these cells will ultimately be able to give rise to functioning neurons, but researchers continue to make progress.
Ultimately, there is much left to discover when it comes to the potential role of being able to regrow brain tissue and regenerative therapies such as stem cells in neurodegenerative conditions and brain injury. What we’ve already seen is promising, however. As experts continue to develop a deeper understanding of how stem cells and neurons can work together, patients with these challenging conditions will likely continue to benefit from evolving treatment options.
