Gibson’s father, aged 92, had multiple age-related diseases for which he was attending the Mayo Clinic. The Mayo Clinic said there was little they could do for Gibson Snr. Mel Gibson then asked about the possibility of using adult stem cells to treat his father. The Mayo Clinic were not supportive of this idea but did agree to discuss the case with Dr Neil Riordan, who offers adult mesenchymal stem cell treatments in Panama (www.cellmedicine.com). Once discussed with Riordan, the physicians at the Mayo Clinic agreed that Gibson Snr may benefit from adult stem cell therapy.
