What it is
Adipose tissue is body fat. Adipose-derived procedures involve collecting a small amount of a person's own fat, usually through a minor procedure, and then using it as is or processing it in some way before placing it elsewhere in the body.
Terms are often mixed together. Fat grafting generally means moving fat tissue from one area to another. Microfragmented adipose tissue refers to fat that has been broken into smaller pieces. Adipose-derived cell procedures can refer to products where cells are separated from the fat, such as stromal vascular fraction (SVF), or grown in a lab.
Regulatory status matters. In the U.S., the only FDA-approved stem-cell products are cord-blood-derived hematopoietic progenitor cell (HPC) products for certain blood and immune disorders, used in specialist transplant settings. Processed or expanded fat-derived cell products are generally regulated as drugs/biologics and are not FDA-approved. The FDA has warned the public about unapproved stem cell products.
How it’s traditionally been approached
Fat grafting has long been used in reconstructive and cosmetic surgery to add volume or fill contour areas. In those settings it is typically performed by surgeons as part of an overall surgical plan.
Interest in fat as a source of cells, often marketed as stem cell therapy, grew as clinics began offering same-day procedures for conditions like joint pain. Evidence for these uses is limited or investigational, and results from research can differ from what clinic marketing suggests.
Conventional approaches to joint pain have usually included things like activity changes, physical therapy, medications, injections, and sometimes surgery, chosen by a licensed clinician after an evaluation. Fat-based options are not a replacement for that conversation, and no one should assume they avoid surgery.
How the right provider may help
A physician-led practice may start with a history, an exam, and a review of prior records or imaging. A licensed clinician can explain which options are established, which are investigational, and which may not suit your situation.
Good questions to ask include: Is this product FDA-approved, and if not, what is its regulatory status? Is this part of a clinical study registered on ClinicalTrials.gov with IRB oversight? What are the risks, the alternatives, and the limits of the evidence?
You can also confirm the clinician's license with your state medical board and ask for written informed consent covering risks and alternatives. A trustworthy provider should welcome these questions, never pressure you to decide quickly, and be honest that outcomes are not guaranteed.
The whole-person view
Body, mind, and stress affect each other. Ongoing pain can disrupt sleep, mood, and activity, and stress or worry can in turn make discomfort feel more intense. Looking at the whole person, not just one joint or one procedure, is often a helpful frame.
Some people find body-based support, such as the approaches listed through Somatic Experiences, useful alongside medical care. Others value talking through the stress of a health decision with a licensed counselor through Therapists.plus. These are complements to a clinician's guidance, not substitutes for it.

Keep in mind
- This page is educational only and is not medical advice. Talk with a licensed clinician about your own situation.
- Most clinic adipose, SVF, and other stem-cell or exosome products are not FDA-approved, and no exosome product is FDA-approved. Holistic or alternative framing does not change FDA status.
- Watch for red flags: cure-all or 'treats everything' claims, paying to join a 'clinical trial,' testimonials in place of evidence, and pressure to travel abroad or across states for treatment.
- Licensed professionals should guide care for serious conditions. For emergencies call 911; in a crisis call or text 988.
Processed or expanded fat-derived cell products are generally regulated as drugs/biologics and are not FDA-approved.

Frequently asked questions
What are adipose-derived cell procedures?
Adipose-derived cell procedures are treatments that use a person's own fat tissue, or cells separated from it, and place them elsewhere in the body. They include fat grafting, microfragmented adipose tissue, and cell-based products made from fat. Their regulatory status and level of evidence vary, so ask a licensed clinician.
Are adipose-derived stem cell therapies FDA-approved?
No, processed or expanded fat-derived cell products are generally regulated as drugs/biologics and are not FDA-approved. In the U.S., the only FDA-approved stem-cell products are cord-blood-derived hematopoietic progenitor cell products for certain blood and immune disorders. The FDA has warned the public about unapproved stem cell products.
What is the difference between fat grafting and microfragmented adipose tissue?
Fat grafting generally means moving fat from one area of the body to another, while microfragmented adipose tissue is fat broken into smaller pieces. Both may be described differently by different clinics. Ask a provider exactly how the tissue is handled and how it is regulated.
Is stem cell therapy using fat used for joint pain?
Some clinics offer fat-based stem cell therapy for joint pain, but evidence is limited or investigational and these uses are not FDA-approved. Results are not guaranteed, and these options should not be assumed to avoid surgery. A licensed clinician can discuss established alternatives and risks.
How do I find a reputable physician-led practice?
Start by confirming the clinician's license with your state medical board and asking about the product's FDA status. Check whether any study is registered on ClinicalTrials.gov with IRB oversight, and request written informed consent covering risks and alternatives. Be cautious of high-pressure sales or testimonial-driven claims.
What questions should I ask before a same-day fat-based procedure?
Ask whether the product is FDA-approved, what the risks and alternatives are, and what evidence supports its use for your situation. Ask who performs the procedure and how their license can be verified. Take your time, since a reputable provider should not pressure you.
