Say a clinic’s flyer calls a stem cell injection “established” for knee pain. “Established” is a marketing word, not an FDA status. The FDA says regenerative medicine therapies have not been approved for orthopedic conditions such as osteoarthritis or knee pain, and that before approval these products require FDA oversight in a clinical trial. So ask which approved product or registered trial the claim relies on.

Safety first: If you have had a procedure and now have fever, spreading redness, severe pain, new weakness, vision changes, or trouble breathing, contact a licensed clinician right away or call local emergency services. This article cannot assess symptoms.
What “approved,” “investigational,” and “established” mean
Approved means the FDA has approved or licensed a product. Investigational means the product is still being studied. The FDA says that before approval, regenerative medicine products require FDA oversight in a clinical trial. It also says it has repeatedly notified manufacturers, clinics, and health care practitioners of the need for Investigational New Drug applications (INDs) to legally administer these products. An IND is an application that lets an unapproved product be studied in people under FDA oversight.
Established is not an FDA category. A seller can use the word freely, so treat it as a claim to check, not as proof.
Stage 1: Write down the exact claim
Save the words used, the product or procedure name, and the condition it is said to treat. “Stem cells are approved” is too vague to check. The FDA’s list of unapproved examples includes stem cells, fat-derived cells (stromal vascular fraction), umbilical cord blood products, amniotic fluid, Wharton’s jelly, ortho-biologics, and exosomes. Capture:
- The name of the product.
- The condition it is said to help.
- Any words like “FDA-cleared,” “FDA-registered,” or “clinical-grade.”
Stage 2: Check the FDA’s approved list
The FDA maintains a page of approved cellular and gene therapy products, which it describes as a listing of licensed and approved products. Search it for the product name you wrote down. If the product is not there, do not assume it is approved. Ask the seller for the FDA documentation.
Check dates. The FDA’s regenerative medicine patient page was last updated April 8, 2024. It says the only FDA-approved stem cell products are blood-forming stem cells from umbilical cord blood. These are approved for disorders that affect the production of blood but, in the FDA’s words, “not approved for other uses.” The approved-products list is a separate page, so use it as your current lookup.
Stage 3: Look for a clinical trial, and read what a listing means
A clinical trial is a research study in people. You can search for studies on ClinicalTrials.gov, which also publishes a guide, How to Read Study Results. As practical questions, check whether the listing matches the product, condition, and location you were told about, and whether the study is still recruiting.
One warning matters most here. The FDA says that including a product in the ClinicalTrials.gov database, or a firm registering with the FDA and listing its product, “does not mean the product is legally marketed.” A listing shows a study or record exists. It does not show that a product works or is approved.
If a clinic names a trial, ask whether you would be joining that trial or buying a separate procedure that only refers to it. Ask for the answer in writing.
Warning boundaries: claims that deserve documentation
The FDA says regenerative medicine therapies have not been approved for the following, so a claim like this deserves a documented answer before you go further:
- Neurological disorders such as multiple sclerosis, ALS, Alzheimer’s, Parkinson’s, epilepsy, or stroke.
- Autism, macular degeneration, blindness, chronic pain, or fatigue.
- Heart disease, emphysema, or COPD.
- Orthopedic conditions such as osteoarthritis, tendonitis, disc disease, or back, hip, knee, neck, or shoulder pain.
- COVID-19, ARDS, or COVID-19 complications.
The FDA also lists reported harms from unapproved products, including infections, blindness, tumor formation, neurological events, inflammatory responses, and contamination. These reports do not predict what will happen to any one person. They are the reason status matters.
Your status verification path
- Write down the exact product name and condition claimed.
- Search the FDA approved cellular and gene therapy products page for that product.
- Ask the clinic in writing: “Is this product FDA-approved for my condition? If not, is it offered under an IND or inside a registered clinical trial? What is the IND or trial identifier?”
- If a trial is named, look it up on ClinicalTrials.gov and compare its details with what you were told.
- Keep the answers. A vague or missing answer is itself useful information.
Decision step: what to do with the answers
If the product is on the FDA list: ask a licensed clinician you already trust how it applies to your situation. The FDA’s own caution is that approved products are not approved for other uses.
If it is not on the list and the clinic cannot name a trial or IND: pause before paying or agreeing to anything, and talk to your own doctor first. Do not stop or change any current medicine because of what you read here.
If a real trial is named: read the listing, then talk with your doctor about whether joining fits your case. Joining a study is your choice, and consent documents should be read closely.

What this guide cannot tell you
The FDA patient page is a general consumer notice, and approval statements can change. This guide does not judge any specific clinic, product, or procedure, and it cannot say whether a treatment will work or is safe for you. Approval status is one question. It does not replace a discussion with your own clinician.
