What it is
Stem cells are cells that can make copies of themselves and can develop into other, more specialized kinds of cells. Scientists study them because the body uses similar cells to maintain and renew certain tissues, such as blood.
'Stem cell therapy' is a broad phrase. It can mean a well-established medical procedure, such as a transplant of blood-forming stem cells from bone marrow or cord blood, or it can mean a product marketed by a clinic for a very different purpose. These are not the same thing, and they do not have the same regulatory status.
The idea behind many treatments is that introduced cells might replace damaged cells or send signals that influence the surrounding tissue. How well this works depends heavily on the specific cell type, the condition, and how a product is made and given. Whether any product is appropriate is a decision for a licensed clinician after an evaluation.
How it’s traditionally been approached
The clearly FDA-approved use is the transplant of blood-forming stem cells, from bone marrow or cord blood, for certain cancers and blood disorders. These procedures are typically done in specialized medical centers by teams of licensed clinicians.
Other uses are mostly studied in research settings. Doctors and scientists conduct registered clinical trials to learn whether a cell-based approach is safe and whether it helps, under oversight and with defined safeguards for participants.
Clinics outside of that research setting also offer products made from bone marrow aspirate, fat (adipose) tissue, umbilical cord or Wharton's jelly, or exosomes. These are marketed for things like joints, back pain, sports injuries, skin, anti-aging or hair loss. These products are generally not FDA-approved for those uses, and the FDA has publicly warned people about unapproved stem cell clinics and products.
How the right provider may help
The right provider may help you sort out what is approved, what is experimental, and what is simply marketing. A good visit generally begins with a conversation about your health history, your goals, and an evaluation. A licensed clinician decides what, if anything, is appropriate for you.
Come prepared with questions. What exactly is the product, and where does it come from? What is its FDA status for this use? What are the specific risks, and what is the realistic chance of benefit? What are the alternatives, including doing nothing? What is the total cost, and may I take time or get a second opinion?
A trustworthy provider welcomes those questions and answers them plainly. You can also ask whether a registered clinical trial, found through ClinicalTrials.gov, might be a legitimate route to experimental care. Providers listed through Providers.plus are licensed, but you should still verify credentials and ask every question above.
The whole-person view
Your body, mind and stress levels affect each other. Living with pain, illness or worry about your health can raise stress, and stress can in turn shape how you feel physically and how you make decisions. This is one reason a hopeful pitch can feel very persuasive when you are struggling.
Some people find that body-based support, such as the approaches offered through Somatic Experiences, helps them feel more settled while they weigh options. Others value talking things through with a licensed counselor, such as those found through Therapists.plus. Neither replaces medical evaluation, and each may simply support the whole person during a big decision.

Keep in mind
- Blood-forming stem cell transplants for certain cancers and blood disorders are the clearly FDA-approved use; stem cell, 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.
- Reported risk categories include infection, immune reaction, tumor formation at the injection site, and permanent injury from unapproved products injected into the eye or spine. Treatment abroad 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.
- 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 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.
- If you have a problem, you can report it through the FDA's MedWatch safety reporting program and to your state medical board. Licensed professionals should guide care for serious conditions; for emergencies call 911, and in a crisis call or text 988.

Frequently asked questions
How does stem cell therapy work?
Stem cell therapy is based on the idea that stem cells can develop into other cell types or send signals that influence nearby tissue. In blood-forming stem cell transplants, healthy cells from bone marrow or cord blood are used to rebuild the blood system for certain cancers and blood disorders. For other uses, how well it works varies and is still being studied, and a licensed clinician must decide what is appropriate.
Is stem cell therapy FDA approved?
Only some uses are. Blood-forming stem cell transplants from cord blood or bone marrow for certain cancers and blood disorders are the clearly FDA-approved use. Stem cell, 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.
Is stem cell therapy safe?
Safety depends on the specific product, how it is made, and how it is given, and unapproved products carry real risks. Reported risk categories include infection, immune reaction, tumor formation at the injection site, and permanent injury from unapproved products injected into the eye or spine. The FDA has warned the public about unapproved stem cell clinics, so ask any provider about the product and its FDA status.
How can I tell if a stem cell clinic is trustworthy?
Look for 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. A trustworthy provider explains the exact product, risks, realistic chance of benefit, alternatives and total cost, and respects your right to walk away. Verifying licensure and getting a second opinion are sensible steps.
Is it risky to get stem cell treatment in another country?
Yes, treatment abroad is materially higher risk. Safety, sourcing and regulatory standards can differ, and a complication is harder to address from a distance. A vetted domestic provider is a safer first step.
How can I access stem cell treatment legitimately or report a problem?
A registered clinical trial, found through ClinicalTrials.gov, is one route to legitimate experimental care, and your own clinician can help you evaluate it. If you suspect a problem, you can report it through the FDA's MedWatch safety reporting program and to your state medical board. For emergencies call 911.
