Is stem cell banking legal in the United States? FDA regulates the storage of human tissue rather than prohibiting it, and its rules expressly provide for tissue stored for the person it came from. A cell product marketed as a treatment is a separate question under separate rules.
TLDR FDA regulates the storage of human tissue rather than prohibiting it. A facility that stores tissue must register with FDA, and registration is not FDA approval. Cell products marketed as treatments are a separate question under separate rules. No adipose-derived product has FDA approval to treat any disease, and banking adipose tissue does not guarantee any future use.

So is stem cell banking legal? FDA regulates the storage of human tissue, and it does not prohibit it. The name is where the confusion starts.
“Stem cell banking” is what people type into a search bar. What gets preserved is your own adipose tissue, which contains adipose-derived stem cells. So the accurate name for the service is adipose tissue banking, or fat banking.
Is Stem Cell Banking Legal Under FDA’s Rules?
FDA regulates tissue storage rather than prohibiting it. Part 1271, FDA’s tissue regulation, never uses the word “legal” for banking. It is a rulebook for how storage has to be done.
Let’s talk specifics. Start with one word: manufacture. 21 CFR 1271.3(e) defines it to include “any or all steps in the recovery, processing, storage, labeling, packaging, or distribution of any human cell or tissue”. In plain words, a facility that stores human tissue is a manufacturer in FDA’s eyes, and Part 1271 applies to it.
The same regulation expressly covers tissue stored for the person it came from, which it calls autologous use. Under 21 CFR 1271.90, that tissue has to be prominently labeled for autologous use only. So FDA has a label requirement for this kind of storage, and a label requirement is a rule for how to do it.
What Does a Facility That Stores Tissue Have to Do?
It has to register with FDA and list every tissue product it handles. FDA’s shorthand for human cells, tissues, and cellular and tissue-based products is HCT/P. 21 CFR 1271.21 requires an establishment to register and submit a list of every HCT/P it manufactures, then update that registration annually in December.
People hear “registered with FDA” and assume FDA has checked the facility and signed off on it. The regulation says otherwise.
21 CFR 1271.27(b) says: “FDA acceptance of an establishment registration and HCT/P listing form does not constitute a determination that an establishment is in compliance with applicable rules and regulations or that the HCT/P is licensed or approved by FDA.” Registration is not FDA approval. Our post on FDA establishment registration goes deeper.
A facility that stores tissue should be registered and able to prove it. They should, but do they? Ask to see the registration.
Where Does Storage End and a Treatment Product Begin?
The line sits at four criteria in 21 CFR 1271.10(a). An HCT/P is regulated solely under section 361 of the PHS Act and Part 1271 only if it meets all four. If it does not, and no exception applies, 21 CFR 1271.20 says it “will be regulated as a drug, device, and/or biological product”.
The table below puts the four criteria in plain words. All four have to be true at once.
| Criterion | What has to be true |
|---|---|
| Minimally manipulated | The tissue has been processed only minimally. |
| Homologous use only | Homologous use is the only intended use. |
| Not combined with another article | Nothing is added except water, crystalloids, or a sterilizing, preserving, or storage agent that raises no new clinical safety concerns. |
| Systemic effect and living cells | It has no systemic effect and does not depend on the metabolic activity of living cells for its primary function, or it is for a listed use such as autologous use. |
Notice the second row. The rule reads intended use from “the labeling, advertising, or other indications of the manufacturer’s objective intent”, so what a company says about a product is part of how FDA classifies it. Whether any given tissue meets all four depends on how it is processed and what it is intended for. Our post on 361 versus 351 walks through the two paths.
How Does FDA Apply Those Criteria to Fat?
FDA starts by treating fat as a structural tissue. Its July 2020 guidance gives an example where cells are isolated from adipose tissue by enzymatic digestion or mechanical disruption, and the result is called stromal vascular fraction. In that case, FDA says, “the HCT/P generally is considered more than minimally manipulated because the processing breaks down and eliminates the adipocytes and the surrounding structural components that provide cushioning and support”.
Intended use works the same way. The same guidance lists filling voids in the face or hands as a homologous use. Using an adipose product to treat arthritis or tendonitis is FDA’s example on the other side, “because regenerating or promoting the regeneration of cartilage or tendon is not a basic function of adipose tissue.”
What does that mean for you? No adipose-derived product has FDA approval to treat any disease. If someone describes stored fat as a future answer for a condition, ask which FDA pathway they mean, and take that conversation to your own licensed provider.
What Does FDA Not Allow?
FDA does not let a registration stand in for approval of a product. The agency says so on its patient information page: “The inclusion of a product in the clinicaltrials.gov database or the fact that a firm has registered with FDA and listed its product does not mean the product is legally marketed.”
Which stem cell products does FDA say are approved? That page, with content current as of 04/08/2024, says: “Currently, the only stem cell products that are FDA-approved for use in the United States consist of blood-forming stem cells (also known as hematopoietic progenitor cells) that are derived from umbilical cord blood.”
The date matters. On December 18, 2024, FDA approved a donor bone marrow-derived cell therapy for a pediatric transplant complication, and its press announcement calls it “the first FDA-approved MSC therapy”. That product is not adipose-derived, so it tells you nothing about fat.
Fat does show up on the other list. The same FDA page names “stromal vascular fraction (fat-derived cells)” among unapproved products, “whether recovered from your own body or another person’s body”. Whether a given treatment is lawful is its own question, and our post on therapy legality takes it state by state.
Do States Add Their Own Tissue Banking Rules?
Some do, and this is the layer people skip. Section 4364 of New York’s Public Health Law says: “No person shall own or operate a bank or storage facility that conducts procurement activity in New York state unless a license has been issued pursuant to this article.” California’s health department says its Tissue Bank Section licenses, among others, “Autologous tissue stored overnight or longer.”
Those are two examples, not a full survey. Ask which state rules apply to the place that would hold your tissue, and start with our guide to state stem cell laws.
What Should You Ask Before You Bank Your Fat?
Ask who does each step, because the regulation counts each step. Save My Fat is a connector that links patients and providers with a U.S.-based tissue bank. A partner provider collects the tissue, and the tissue bank processes and cryopreserves it.
Then ask how the tissue will be processed and what the paperwork says it is intended for. Ask which state rules apply. So it all goes back to keeping storage and treatment apart, and if anyone promises you a treatment along the way, bring that promise to your own licensed provider.
Frequently Asked Questions
Does FDA registration mean a tissue bank has FDA approval?
No. The regulation says FDA’s acceptance of a registration is not a determination that the establishment is in compliance or that its product is licensed or approved by FDA. Registration is not FDA approval.
Is stem cell banking legal in every state?
FDA’s tissue rules are federal, and some states add licensing rules of their own. This post gives two examples, not a survey of every state. Ask the facility which state rules apply to it.
Is banking fat the same as getting a stem cell treatment?
No. Banking is storage, which FDA regulates under its tissue rules. A cell product given as a treatment is a separate question, and no adipose-derived product has FDA approval to treat any disease.
Can stored fat be used for a treatment later?
No one can tell you that today. Any future use depends on FDA regulatory status, physician guidance, and the availability of approved or investigational pathways at that time. Banking does not guarantee any future use, so talk it through with your own licensed provider.
Key Takeaways
FDA regulates the storage of human tissue rather than prohibiting it. A facility that stores tissue has to register with FDA, and registration is not FDA approval. Whether a tissue product stays under the tissue rules depends on four criteria, including how it is processed and what it is intended for. No adipose-derived product has FDA approval to treat any disease. Ask who stores the tissue, and take any treatment question to your own licensed provider.
Save My Fat connects patients and providers with a U.S.-based tissue bank. It is not a tissue bank, a laboratory, a medical practice, or a treatment provider. Stem cell and regenerative medicine regulations vary by state, including specific informed-consent and disclosure requirements in Florida, Utah, California, Georgia, and Tennessee governing tissue and stem cell services. Banking adipose tissue does not connect patients to any treatment pathway, and any future use depends on FDA regulatory status, physician guidance, and the availability of approved or investigational pathways at that time.
If you are weighing adipose tissue banking for potential future use, you can review current pricing or start a conversation through the contact page.
