What it is
The term "unapproved stem cell products" generally describes stem cell, mesenchymal stem cell (MSC), bone marrow aspirate, adipose-derived (fat), umbilical cord or Wharton's jelly, and exosome products offered outside the FDA's approval process. They are often marketed for joints, back pain, sports injuries, skin, anti-aging or hair loss.
The clearly FDA-approved use of stem cells is blood-forming stem cell transplantation, using cells from bone marrow or cord blood, for certain cancers and blood disorders. That approval applies to those specific uses. It does not extend to other products or other conditions.
The FDA has publicly warned consumers about unapproved stem cell clinics and products. Reported risk categories include infection, immune reaction, tumor formation at the injection site, and permanent injury when unapproved products are injected into the eye or spine. This page doesn't give rates, because the right way to weigh risk for any person is with a licensed clinician.
How it’s traditionally been approached
Approved blood-forming stem cell transplants have a long, established place in medicine. They are carried out by specialized transplant teams in medical centers under oversight and defined safety standards.
For conditions such as joint pain, back pain, sports injuries, skin concerns and hair loss, care has traditionally relied on options such as physical therapy, medication, lifestyle changes, procedures and surgery. A licensed clinician decides what fits after an evaluation.
Stem cell and exosome products marketed for these concerns have often been sold by clinics outside the approval pathway. Some people explore them through registered clinical trials, which can be a legitimate route to experimental care. ClinicalTrials.gov is the public registry where such studies are listed.
How the right provider may help
A thoughtful provider may help you sort out what is approved, what is experimental and what is simply marketing. A visit generally begins with your history, your goals and an evaluation. A good provider welcomes questions and doesn't rush you.
Useful questions include: What exactly is the product, and where does it come from? What is its FDA status for this use? What are the specific risks? What is the realistic chance of benefit? What are the alternatives, including doing nothing? What is the total cost, and may I walk away?
A provider may also help you look for a registered clinical trial, or talk through established options and a second opinion. A vetted domestic provider is generally a safer first step than treatment abroad. Medical tourism carries materially higher risk, because safety, sourcing and regulatory standards differ and complications are harder to address from a distance.
The whole-person view
Body, mind and stress affect each other. Chronic pain, hair loss, aging concerns or an injury can bring worry and a strong wish for relief, and that hope can make bold marketing feel persuasive. Slowing down and getting support can help you make steadier decisions.
Body-based support such as Somatic Experiences may help some people work with stress held in the body. Talk therapy through Therapists.plus may help with the worry and pressure that often come with health decisions. Neither replaces a medical evaluation, and Providers.plus lists licensed providers.

Keep in mind
- Red flags: 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.
- Informed consent should cover the exact product and its FDA status, specific risks, realistic chance of benefit, alternatives including doing nothing, total cost disclosure, and your right to walk away. This page is not a consent form.
- To report a suspected problem, you can describe it to the FDA's MedWatch safety reporting program and to your state medical board. Check the official sites for how to file.
- Serious conditions need care guided by licensed professionals. For emergencies call 911, and in a crisis call or text 988.

Frequently asked questions
What are unapproved stem cell products?
Unapproved stem cell products are stem cell, MSC, bone marrow aspirate, adipose-derived, umbilical cord or Wharton's jelly, and exosome products that lack FDA approval for the uses they are marketed for. They are often promoted for joints, back pain, sports injuries, skin, anti-aging or hair loss. Ask any provider for the exact product and its FDA status.
Are stem cell treatments FDA approved?
Only some are. Blood-forming stem cell transplants from cord blood or bone marrow, used for certain cancers and blood disorders, are the clearly approved use. Products marketed for joints, back pain, sports injuries, skin, anti-aging or hair loss are generally not FDA-approved for those uses.
Is stem cell therapy safe?
Safety depends on the product, its source, the use and the setting, so no blanket answer is possible. For unapproved products, reported risks include infection, immune reaction, tumor formation at the injection site, and permanent injury from injections into the eye or spine. The FDA has issued public warnings about unapproved clinics, which is why stem cell therapy safety is worth researching before you decide.
How can I tell if a stem cell clinic is a red flag?
Warning signs include guaranteed results, "cure" or "regrow" claims, refusal to name the product or its FDA status, pressure to decide quickly, and discouragement of a second opinion. Any one of these is a reason to pause and get an independent opinion from another licensed clinician.
Is it safe to get stem cell treatment abroad?
Treatment abroad is materially higher risk. Safety, sourcing and regulatory standards differ, and a complication is harder to address from a distance. A vetted domestic provider is usually a safer first step.
How do I report a problem with a stem cell product?
You can report a suspected problem to the FDA's MedWatch safety reporting program and to your state medical board. Keep notes on the product, the provider and what happened. Seek care from a licensed clinician, and call 911 in an emergency.
