FDA stem cells
FDA stem cell court cases total 215, of which 178 are federal court decisions concerning the FDA and stem cells. Of these, the FDA was a party in only a few of them, all in federal court.
At the U.S. Court of Appeals, there have been very few decisions concerning the extent of FDA authority over this issue. The Fifth Circuit has never addressed FDA authority (or lack thereof) over stem cell therapy.
Generally the FDA attempts to block and impede the use of adult stems cells as much as the FDA possibly can, and often beyond what Congress has authorized the FDA to do.
11th Circuit
The Eleventh Circuit is the only appellate court to address the issue of the scope of the FDA authority to impede with stem cell therapy, and it appears that the defendant clinic did not really challenge FDA authority in the case:
| “ | US Stem Cell Clinic, LLC, its parent company, and its chief scientific officer (collectively, the Clinic) offer a procedure in which they remove fat tissue from a patient, isolate the portion containing stem cells, and inject that portion back into the patient. This procedure purportedly treats all manner of chronic conditions, from pain to Parkinson's disease.
The United States Food and Drug Administration is skeptical of the Clinic's claims. It sued the Clinic, alleging the stem cell procedure violates the Federal Food, Drug, and Cosmetics Act (codified at 21 U.S.C. §§ 301 et seq.). The district court granted summary judgment for the FDA and enjoined the Clinic from offering its procedure until it can demonstrate to the FDA that its stem cell therapy is safe and effective. The Clinic appeals, arguing it is exempt from regulation because the procedure falls into either the "same surgical procedure" exception or the "361 HCT/P" exception to regulation under the FDCA. See 21 C.F.R. § 1271.15(b); id. § 1271.10. We disagree: The procedure does not fall within the first exception because the biological material implanted into the patient is not the same as that removed and the procedure does not fall within the second exception because the Clinic intends the stem cells to perform functions after the procedure beyond the basic functions the stem cells performed prior to the procedure. We therefore affirm the judgment of the district court. |

United States v. US Stem Cell Clinic, Ltd. Liab. Co., 998 F.3d 1302, 1304 (11th Cir. 2021).
This decision is notable for its passage against finding ambiguity in a regulation, and then deferring to a federal agency:
| “ | There was a time when a court faced with a regulation that seemed "impenetrable on first read" might simply "wave the ambiguity flag" and defer to the agency's interpretation. Kisor v. Wilkie, 139 S. Ct. 2400, 2415, 204 L. Ed. 2d 841 (2019). No longer. The Supreme Court recently clarified that judicial deference is appropriate only if a regulation is "genuinely ambiguous." Id. Before declaring a regulation genuinely ambiguous, we must "exhaust all the traditional tools of construction," which entails "carefully consider[ing] the text, structure, history, and purpose of [the] regulation." Id. (internal quotation marks omitted). We will consider the parties' textual arguments, giving the agency's view no special weight "except to the extent it has the 'power to persuade.'" Id. at 2414 (quoting Skidmore v. Swift & Co., 323 U.S. 134, 140, 65 S. Ct. 161, 89 L. Ed. 124 (1944) ("The weight of [an agency's interpretation] will depend upon the thoroughness evident in its consideration, the validity of its reasoning, [and] its consistency with earlier and later pronouncements")). In this case, our tools of construction resolve the apparent ambiguity in the FDA's favor, so we need not decide whether to defer to the interpretation expressed in the Guidance Document. | ” |

The Fifth Circuit found that "extracellular vesicle ("EV") [is a] product similar to stem cell therapy." Direct Biologics, L.L.C. v. McQueen, 63 F.4th 1015, 1017 (5th Cir. 2023) (deciding a trade secret-related issue.
In the 1990s, there was advocates of stem cell rescue procedures for breast cancer:
| “ | The number of stem cell rescue procedures performed worldwide is increasing. By 1992, some 19,000 transplants had been performed, up from over 2,500 performed as of 1986. And the total number of transplants is expected to reach 251,000 by 1998 .... | ” |
Smith v. Office of Civilian Health & Med. Program of the Uniformed Servs., 97 F.3d 950, 968 (7th Cir. 1996) (denying federal coverage for the procedure based an assertion that it was unproven).
