What it is
"Stem cell therapy" is a broad phrase that covers very different things. At one end are blood-forming (hematopoietic) stem cell transplants, which use cells from bone marrow, peripheral blood or umbilical cord blood. These are the clearly FDA-approved use, and they are for certain cancers and blood disorders.
At the other end are products sold by some clinics as stem cell treatments for other purposes. These include bone marrow aspirate, adipose-derived (fat) cells, mesenchymal stem cells (MSCs), umbilical cord or Wharton's jelly products, and exosome products. When marketed for joints, back pain, sports injuries, skin, anti-aging or hair loss, they are generally not FDA-approved for those uses.
The FDA has publicly warned consumers about unapproved stem cell clinics and products. Words like "regenerative," "natural" or "your own cells" do not mean a product is approved or proven safe. Approval means the FDA has reviewed evidence for a specific product and a specific use.
How it’s traditionally been approached
Blood-forming stem cell transplantation has long been handled by specialized medical teams in hospitals and transplant centers. A licensed clinician decides whether it is appropriate after a full evaluation, and the process is closely monitored.
For conditions like joint pain, back pain or sports injuries, care has traditionally included approaches such as physical therapy, medication, activity changes, injections with established products, and sometimes surgery. Which of these fit a person is a decision for a licensed clinician.
Experimental uses of stem cells have traditionally been studied through registered clinical trials, which have oversight and defined safety rules. ClinicalTrials.gov is a public registry where people can search for such trials generally. Some clinics outside that structure sell unapproved products directly to consumers, and that is where much of the FDA's concern lies.
How the right provider may help
The right provider may help you sort out what is actually approved, what is experimental and what is simply marketing. A good visit usually begins with a careful evaluation of your history and goals, and a clear explanation of options, including conventional care and doing nothing.
Consider asking: What is the exact product, and where does it come from? What is its FDA status for my condition? What are the specific risks, such as infection, immune reaction, or tumor formation at the injection site? What is the realistic chance of benefit? What are the alternatives? What is the total cost, and can I walk away at any point?
A trustworthy provider welcomes a second opinion and may point you to a registered clinical trial if you want experimental care. Informed consent should cover the exact product and FDA status, specific risks, realistic chance of benefit, alternatives, total cost disclosure and your right to walk away.

The whole-person view
Living with pain, illness or worry about aging can be stressful, and stress can in turn affect sleep, tension and how the body feels. When people are hopeful and hurting, bold promises can feel especially persuasive, so taking time to decide is a form of self-care.
Body-based support, such as the approaches offered by our sponsor Somatic Experiences, may help some people feel more settled while they weigh decisions. Talking with a licensed counselor through Therapists.plus may also help you sort through fear, hope and difficult choices. These are supportive options that sit alongside medical care, not replacements for it.

Keep in mind
- Only blood-forming stem cell transplants for certain cancers and blood disorders are clearly FDA-approved. Stem cell, MSC, bone marrow aspirate, adipose-derived, umbilical cord and exosome products marketed for joints, back pain, sports injuries, skin, anti-aging or hair loss are generally not approved for those uses.
- Red flags include guarantees of results, "cure" or "regrow" language, refusal to name the product or its FDA status, pressure to decide quickly, and discouraging a second opinion. Reported risks of unapproved products include infection, immune reaction, tumor formation at the injection site, and permanent injury when injected into the eye or spine.
- Treatment abroad (medical tourism) is materially higher risk because safety, sourcing and regulatory standards differ and complications are harder to address from a distance. A vetted domestic provider is a safer first step. To report a suspected problem, you can use the FDA's MedWatch safety reporting program and your state medical board.
- Licensed professionals should guide care for any serious condition. For emergencies call 911; in a crisis call or text 988. This page is educational only, not medical, legal or financial advice.

Frequently asked questions
Is stem cell therapy FDA approved?
Only for certain uses. Blood-forming stem cell transplants from bone marrow or cord blood are FDA-approved for certain cancers and blood disorders. Stem cell products marketed for joints, back pain, sports injuries, skin, anti-aging or hair loss are generally not FDA-approved for those uses.
Are stem cell injections for knee pain FDA approved?
Generally no. Stem cell, bone marrow aspirate, adipose-derived, umbilical cord and exosome products marketed for joint pain are generally not FDA-approved for that use. Ask a licensed provider about the exact product and its regulatory status.
Why are some stem cell clinics allowed to operate if the products are not approved?
Some clinics operate in regulatory gray areas or sell products without FDA review, and the FDA has issued public warnings about this. Being open for business does not mean a product is approved or proven safe. Always ask the clinic directly for the product's FDA status.
What are the risks of unapproved stem cell treatments?
Reported risk categories include infection, immune reaction, and tumor formation at the injection site. Permanent injury has also been reported when unapproved products were injected into the eye or spine. A licensed clinician can explain how these risks apply to you.
How can I find legitimate experimental stem cell care?
A registered clinical trial is the main route to legitimate experimental care. You can search ClinicalTrials.gov, a public registry, and discuss any trial with your own licensed clinician. Trials have oversight that direct-to-consumer clinics may lack.
How do I report a problem with a stem cell treatment?
You can report a suspected problem through the FDA's MedWatch safety reporting program and file a complaint with your state medical board. Keep records of the product, provider and what happened. In an emergency call 911.
