About R3 Stem Cell

R3 Stem Cell was founded in 2011 and is led by its founder and CEO, Dr. David Greene. According to the company’s 2026 announcements, R3 Stem Cell Mexico operates a clinic network in Tijuana, Cancún, and Puerto Vallarta and offers regenerative therapies using cells derived from sources such as bone marrow and umbilical tissue. R3 publishes package pricing and patient stories on its website. Because these details can change, review them directly with R3.

How to Read R3 Stem Cell Reviews

Reviews of R3 Stem Cell in Tijuana—like reviews of any clinic—appear in several places, and each type should be read differently:

  • Satisfaction figures and testimonials published by a clinic describe patient experiences, which are valuable, but they are not the same as measured medical outcomes.
  • Independent reviews tell you about communication, logistics, and service. Check the dates, since protocols and staff change over time.
  • Video and podcast stories are often compelling, but they are selected for sharing.

Ask any clinic how it tracks outcomes after patients go home, what it measures, and how long it follows up. A thoughtful answer is often more informative than a star rating.

Stem Cell Reviews vs. Stem Cell Research

Controlled trials frequently tell a more cautious story than reviews do:

  • For knee osteoarthritis, a 2025 Cochrane review found that stem cell injections may improve pain and function slightly compared with placebo, based on low-certainty evidence (Cochrane Database of Systematic Reviews, 2025).
  • For autism, a randomized trial of 180 children found that cord blood infusion was safe but did not improve the primary social communication outcome across the full group (Dawson et al., Journal of Pediatrics, 2020).
  • For safety, a review of 55 randomized trials of MSCs delivered into the bloodstream found an increased rate of temporary fever but no increase in infection, blood clots, death, or cancer (Thompson et al., EClinicalMedicine, 2020).

None of this means stem cell therapy cannot help anyone. It means you deserve a clinic that shows you this evidence before you pay.

A Side-by-Side Checklist for Comparing Tijuana Stem Cell Clinics

Licensing is a good place to start. A University of California San Diego study of Tijuana regenerative medicine clinics found that 13 claimed to be licensed, but only one matched available licensing information (Chavez et al., Stem Cell Research & Therapy, 2021). Use the questions below with R3, CPI, Renovo, or any other clinic. The right-hand column shows Renovo’s answers.

Question to ask Why it matters Renovo's answer
What is your COFEPRIS license number? Licensing claims do not always match public records. COFEPRIS Health License COFEPRIS-02-002-A.
What cells do you use? Cell type and source shape the protocol. Umbilical cord–derived MSCs for orthopedic and general protocols; dental pulp stem cells for neurological protocols.
Where are cells expanded and tested? Laboratory standards affect quality and sterility. Certified, licensed biotechnology laboratories; no on-site expansion.
Do you verify cells on arrival? Cell counts and viability can change in transit. Yes—an independent secondary cell count and viability check before every treatment.
How is the injection guided? Precise placement matters for joints and the spine. Ultrasound or fluoroscopy; higher-complexity applications take place in a specialized Procedure Room.
Do you ever decline patients? Screening signals a safety-first practice. Yes, when contraindications such as active, uncontrolled infections or medical instability are present.
How is pricing presented? Itemized quotes prevent surprises. A written quote after medical review; stem cell–only pricing generally $2,100–$9,900 USD.
