Are stem cell therapies supported by research?
There is a wealth of scientific research on stem cells. We have a dedicated section exclusively showcasing the latest innovative studies on regenerative therapies here.
The clinical use of hematopoietic stem cells has been extensively documented, with decades of successful experience in bone marrow stem cell transplants for blood cancers like leukemia and other diseases. To provide some historical context, the first successful bone marrow transplant took place in 1968—over 50 years ago.
The scientific research leading to mesenchymal stem cell (MSC) applications in humans has grown exponentially. Thousands of papers and studies have been published at the preclinical (lab and animal models) and clinical (human) levels, increasing our understanding of their potential to help with many diseases.
More human trials and clinical evidence for cellular treatments have been published in the areas of musculoskeletal, pulmonary, neurology, cardiology, and rheumatology. Due to the volume of trials, we can start by looking at a systematic review. This type of research is at the top of the hierarchy of scientific evidence, gathering and analyzing multiple studies or papers on a specific topic to provide a comprehensive and reliable conclusion based on the existing evidence, going beyond what any single study can prove.
Mesenchymal Stem Cells Current Clinical Applications: A Systematic Review
This systematic review compiled over 1,100 registered clinical trials studying the use of MSCs to treat various conditions. Most of these trials focus on treating injuries and diseases in fields like traumatology (injury treatment), neurology (nervous system disorders), cardiology (heart diseases), and immunology (immune system disorders).
Here are the key findings:
- The results have been promising, with positive outcomes and no severe side effects. MSCs have been found to be safe and effective in repairing damaged tissues and modulating the immune system.
- They’ve also been found to have potential uses in treating a wide range of conditions, such as Parkinson’s disease, and even immune-related conditions like Crohn’s disease.
- They help by replacing damaged cells or releasing substances that stimulate the body’s repair mechanisms.
As you can see, MSCs’ ability to transform into different cell types and their role in tissue repair make them a powerful tool in regenerative medicine.
Ongoing scientific research on stem cells and clinical trials are essential for understanding their full potential and developing new treatments for diseases that currently have limited options.

Let’s also examine this review paper on how stem cells can help in aging in older adults and frailty.
Attenuation of Frailty in Older Adults with Mesenchymal Stem Cells
This paper explores how mesenchymal stem cell therapy (MSC) can help reduce frailty in older adults.
Frailty is a condition often observed in older adults, characterized by a decline in strength and energy. Common symptoms include tiredness, weight loss, slower walking speed, and diminished ability to engage in daily activities. This weakness is partially attributed to muscle loss and chronic inflammation.
Frail individuals face a considerably higher risk of falls, disability, and mortality, particularly after undergoing surgery. You may have witnessed these symptoms in your parents, grandparents, or other elderly family members.
There are currently no treatments for frailty beyond preventive and traditional measures such as improved nutrition, physical exercise, and mental health interventions, which have yielded mixed results.
This study examined small clinical trials indicating that mesenchymal stem cell therapy can be safely administered to frail older adults and may enhance their physical function and quality of life.
Here are the key findings:
- MSCs help by reducing chronic inflammation, improving muscle regeneration, and enhancing the immune system.
- They can also release factors that promote tissue repair and reduce the severity of frailty symptoms.
- Early innovative studies on regenerative therapies have shown promising results, such as improved physical activity and better quality of life in frail older adults who received MSC therapy.
- The stem cell therapy appears to be safe, with no serious adverse effects reported in the trials.
The research indicates that MSCs hold significant promise as longevity solutions by addressing the underlying causes of frailty, potentially improving the health of elderly individuals. This is particularly significant as the world’s population continues to age; regenerative treatments offer a new and promising approach to helping older adults maintain their independence and well-being.

Let’s delve deep into the research on umbilical cord-derived mesenchymal stem cells (UC-MSCs).
Umbilical Cord Mesenchymal Stromal Cell Transplantations: A Systemic Analysis of Clinical Trials
This systematic analysis reviewed and analyzed the safety and effectiveness of UC-MSCs in treating various diseases based on clinical trials. The research looked at 93 clinical trials involving 2,001 patients with 53 different diseases, including neurological diseases, blood disorders, immune system diseases, liver diseases, and heart diseases.
Some key findings were:
- The studies did not report any long-term negative effects, such as tumor formation or rejection of the transplanted cells. Patients generally tolerated the umbilical cord-derived mesenchymal stem cell transplants well, with few short-term side effects.
- Many studies show that UC-MSCs provide therapeutic benefits, such as improved clinical symptoms and laboratory results.
- Innovative studies on regenerative therapies reported improvements in conditions like multiple sclerosis and spinal cord injuries, with patients showing better motor function and reduced symptoms.
- UC-MSCs helped enhance blood cell production and reduce complications in patients undergoing bone marrow transplants.
- UC-MSCs effectively treat autoimmune diseases like systemic lupus erythematosus (SLE), reducing disease activity and improving organ function.

What’s the future of scientific research on stem cells?
The body of research supporting the use of stem cells is extensive and growing. From regenerative medicine and neurological disorders to blood diseases and diabetes, stem cell therapy offers a promising avenue for developing new and effective treatments.
