The professional career of the 56-year-old accused doctor — one of several physicians facing charges in connection with the death of Giorgos Mazonakis — appears to have taken some remarkably different turns over the years. Starting out in internal medicine and hematology, with a doctoral thesis and peer-reviewed publications to his name, his path eventually veered into a very different territory: “holistic” and “regenerative medicine,” homeopathy, and CD34+ stem cell applications, with a particular focus on anti-aging treatments.

In 2001, his name appeared among the authors of a scientific paper published in the British Journal of Haematology, focusing on platelet function. In the years that followed, however, his professional activities took a sharp turn, with his Stem Cell Clinic promoting a blend of conventional medicine and complementary and alternative practices.
Giorgos Mazonakis: The doctor’s presentation in South Korea and the CD34+ stem cell protocol
The most striking expression of this shift came in November 2025 in South Korea, where Ilias Theodoropoulos presented a paper titled “Biological Age Reversal Through Integrative Treatment and CD34+ Stem Cell Therapy: A Quantitative Analysis” at the 15th International Forum of Future Medicine & Aesthetic Surgery (2025 Fall IFFAS). The retrospective analysis covered 42 patients, aged between 37 and 76, who had followed the clinic’s protocol between February 2023 and June 2025.
The protocol was divided into two phases. The first phase, lasting three to six months, included personalized nutrition plans, exercise, weight management, adjustment of conventional medication, vitamins, herbal supplements, and homeopathic preparations. In the second phase, patients underwent — according to the presentation — autologous CD34+ cell therapy using the Miracell Smart M-Cell 2 system, while all previous interventions continued in parallel.
Biological age was assessed using the PhenoAge index, a composite biomarker calculated from a range of blood and biochemical parameters. According to the data presented by Mr. Theodoropoulos, the average chronological age of patients was 58.3 years, while upon completion of the protocol, the mean PhenoAge dropped to 50.5 years. The clinic claimed an overall “rejuvenation” of approximately 7.9 years — attributing a reduction of 4.4 years to the first phase and an additional 3.45 years to the CD34+ phase.
Also noteworthy is the description of the individual treatment applications outlined in the presentation. Four light stimulation programs are mentioned — blue, green, yellow, and red — each attributed with different therapeutic effects, ranging from immune system and liver support to applications targeting the cardiovascular system, joints, bones, and anti-aging.
In September 2025, the clinic announced it had administered over 600 CD34+ treatments since February 2023. The accompanying statement spoke of lives “touched,” health “restored,” pain “relieved,” and hope “renewed,” while describing the cells as “Divine Cells” — crediting them with “the power of renewal” and heralding “a new era of healing and regeneration.”
The scientific validity of these claims comes under fire
It should be noted that Manolis Nikolousis — a hematologist specializing in bone marrow transplantation and director at the Yas Clinic Group — was asked to comment on the above findings by Parapolitika. He openly challenges the scientific basis of such claims, systematically dismantling the notion that any treatment can genuinely “reverse” biological age.
