Stem cell therapy in Panama vs Mexico comes down to who regulates the cells and how far you travel to reach them. Panama governs cell therapy through its health ministry (MINSA) under Executive Decree 179 of 2018, Mexico through its federal regulator, COFEPRIS, and in both countries the leading clinics make their cells in-country; from Los Angeles, Panama City is about 9 hours door to door and Tijuana is 2.5.
The Cayman Islands are compared on the same lines, including where Mexico isn't the obvious winner.
The regulator is the country, not the clinic. "Regulated" doesn't mean much without knowing who the regulator is. Here's who it is in each of the three.
Comisión Federal para la Protección contra Riesgos Sanitarios
Mexico's federal health regulator. Cell therapy in Mexico is regulated by COFEPRIS, and the leading programs make their cells in-country and give them inside hospitals.
Ministerio de Salud
Health-ministry oversight of medical facilities. The use of human cells and tissues is governed by Executive Decree 179 (2018), which puts uses outside transplant on a research track, under a protocol authorized by the national research bioethics committee. In practice, the leading Panama clinics manufacture their cells in-country, at their own cGMP labs in Panama City.
Health Practice Commission
A small regulator for a small jurisdiction. The Health Practice Commission certifies health care facilities and registers practitioners. The best-known Cayman program offers treatment inside a clinical study, with cells made in a U.S. lab and imported.
All three have a named health authority. In Mexico, care is regulated by COFEPRIS. Panama has domestic cGMP manufacturing and runs cell therapy on a research-track frame under Executive Decree 179. In Cayman, the Health Practice Commission certifies the facility and treatment is offered inside a study. This page doesn't grade one regulator against another. The differences that are easiest to check are where the cells are made and how far you travel.
Every node in the chain is a temperature-controlled handoff with its own paperwork. Mexico and Panama keep the lab, release, and infusion inside one regulatory jurisdiction, so those chains have the fewest hops. Cayman clinics typically bring finished cells in from a U.S. lab, which adds a courier and customs step. Domestic manufacturing isn't automatically better, but a shorter chain is easier to audit.
Door-to-door from a representative U.S. metro (Los Angeles), under typical conditions. Stem-cell patients are often older, often deconditioned, often traveling with a caregiver: proximity matters more than the headline flight time suggests. The airline's number never includes baggage claim.
2.5 hr door to door
Drive to San Diego, then Celva transfer
Mexico: overland-accessible from CA, AZ, NM, TX
About 9 hr door to door
Nonstop flight + transfer
Panama: direct flights from LAX, JFK, MIA
10.5 hr door to door
Connection (typically MIA)
Cayman: usually via Miami. A nonstop from LAX runs about once a week
From the East Coast everything is a flight, and Mexico stays competitive: Tijuana is a nonstop into San Diego, about 6 hours from New York, plus 25 to 30 minutes from San Diego with a Celva driver. If you live within driving distance of San Diego, El Paso, or McAllen, Mexico is uniquely accessible.

If you're spending real money and real time on this decision, here's the rough rule a sober consultant would give.
Your physician wants U.S.-style hospital backup, you care about where the cells came from, or you want a single-day program rather than a multi-day stay. Most U.S. patients fit here, coast to coast: a drive or short nonstop out West, a routine domestic-length flight from the East.
You specifically want Stem Cell Institute, and you want a structured program of 3 to 5 days with a single clinic that reports more than 20,000 patients.

"COFEPRIS-licensed" / "MINSA-approved" / "Cayman HPC-certified" sound similar but aren't equivalent. Ask what each one covers before treating any of these as proof of quality. Section 3 of the Learn library covers the cells question separately.
