What it is
Stem cells are cells that can divide and give rise to other kinds of cells. The term gets used loosely, so it helps to separate the categories by source: blood-forming (hematopoietic) stem cells from bone marrow, circulating blood or umbilical cord blood; mesenchymal stem/stromal cells (MSCs); bone marrow aspirate; adipose-derived (fat) cells; umbilical cord or Wharton's jelly products; and exosome products.
FDA status is the most important line to understand. Blood-forming stem cell transplants using cord blood or bone marrow are the clearly FDA-approved use, and they are used for certain cancers and blood disorders under specialist care. Stem cell, MSC, bone marrow aspirate, adipose-derived, umbilical cord / Wharton's jelly and exosome products marketed for joints, back pain, sports injuries, skin, anti-aging or hair loss are generally NOT FDA-approved for those uses.
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 from unapproved products injected into the eye or spine. These risks are described here in general terms only, and no one can promise how any individual will respond.
How it’s traditionally been approached
Blood-forming stem cell transplantation has traditionally been carried out in specialized medical centers by teams who evaluate the patient, match the donor or source, and monitor recovery over time. It is a regulated, carefully supervised area of medicine.
Outside of that setting, many other cell-based products have been offered by independent clinics, often under the label of regenerative or wellness medicine. Some are used within registered clinical trials, which is the legitimate route to experimental care. Others are sold directly to consumers without FDA approval for the conditions being advertised.
Conventional approaches to joint pain, back pain, sports injuries, skin concerns or hair loss have usually included options such as physical therapy, medication, lifestyle changes, or procedures with established regulatory standing. Whether any of these fit a given person is a decision for a licensed clinician after an evaluation.
How the right provider may help
The right provider may help you sort established care from unproven offerings. A visit generally starts with a health history and an evaluation, followed by a conversation about options, including doing nothing. Good questions to ask include: What exactly is the product, and where does it come from? What is its FDA status for my condition? What are the specific risks? Is there a registered clinical trial instead?
Red-flag checklist: guarantees of results; words like "cure" or "regrow"; refusal to name the product or its FDA status; pressure to decide quickly; and discouraging a second opinion. Any one of these is a good reason to pause and seek another view from an independent licensed clinician.
Informed consent should include the exact product and its FDA status, the specific risks, a realistic chance of benefit, alternatives including doing nothing, total cost disclosure, and your right to walk away. Use this as a checklist for your conversation. This page is not a consent form and does not replace one from a licensed provider.
The whole-person view
Body, mind and stress affect each other. Chronic pain, an injury or a frightening diagnosis can bring worry and a strong wish for a quick fix, and that urgency can make bold marketing feel more convincing. Slowing down, sleeping, moving as your clinician allows, and leaning on trusted people can support clearer decisions.
Some people find body-based support such as Somatic Experiences helpful for how stress is held in the body, and others value talk therapy through Therapists.plus while they weigh hard health choices. These are complements to medical care, not substitutes for it, and they do not replace guidance from your licensed clinician.

Keep in mind
- Only a licensed clinician can decide what is appropriate for you after an evaluation, and licensed professionals should guide care for any serious condition, including cancer and blood disorders.
- 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.
- Registered clinical trials, which you can search generically on ClinicalTrials.gov, are a route to legitimate experimental care.
- For emergencies call 911; in a crisis call or text 988.

Frequently asked questions
What are the main types of stem cell therapy?
The main types of stem cell therapy are blood-forming (hematopoietic) transplants from bone marrow or cord blood, and a wider group of products using MSCs, bone marrow aspirate, adipose-derived cells, umbilical cord / Wharton's jelly or exosomes. Blood-forming transplants are the clearly FDA-approved use, for certain cancers and blood disorders. The wider group is generally not FDA-approved for joints, back pain, sports injuries, skin, anti-aging or hair loss.
Which types of stem cell therapy are FDA-approved?
Blood-forming stem cell transplants from cord blood or bone marrow, used for certain cancers and blood disorders, are the clearly FDA-approved use. Products marketed for orthopedic, cosmetic or anti-aging purposes are generally not approved for those uses. Ask any provider to name the exact product and its FDA status in writing.
What are the risks of unapproved stem cell products?
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 issued public warnings about unapproved clinics and products. Risks differ by product and person, so discuss them with a licensed clinician.
What are red flags when choosing a stem cell provider?
Warning signs 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. If you see any of these, pause and get an independent opinion from another licensed clinician.
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 you can also contact your state medical board about a licensed provider's conduct. Seek care from a licensed clinician for any health concern, call 911 in an emergency, and look up the official contact details directly from the FDA and your state board.
Is it safe to get stem cell therapy abroad?
Treatment abroad is materially higher risk because safety, sourcing and regulatory standards differ, and a complication is harder to address from a distance. A vetted domestic provider is a safer first step. You can also look for registered clinical trials on ClinicalTrials.gov as a route to legitimate experimental care.
