Silvina Pastrana, M.D. is medical director of the Stem Cell Center Buenos Aires and Regentherapy Puerto Madero. Dr. Pastrana heads a staff of medical specialists in orthopedics, rheumatology, medical clinic and cosmetic surgery, performing procedures that incorporate stem cell therapies. Dr. Pastrana also serves as a staff surgeon for the Hospital Dr. Prof. Luis Güemes.
Dr. Pastrana received her medical degree at the Argentinian University of Buenos Aires and completed her residency at the Hospital Dr. Prof. Luis Güemes in Buenos Aires. She continued her  postgraduate studies in Spain while gaining knowledge about minimally invasive and percutaneous surgery.

Alfredo Hoyos, M.D., Global Stem Cells Group’s chief scientific officer (CSO), is a renowned  board-certified plastic surgeon from Bogotá, Colombia. Dr. Hoyos earned his medical degree at El Rosario University in Bogotá and performed his residency in plastic surgery at the Rosario – Saint Joseph Hospital, also in Bogotá.
The inventor of High Definition Liposculpture (HDL), Dynamic Definition Lipoplasty (4D), and other advanced body contouring techniques, Dr. Hoyos has been an innovator since early in his career, embracing the potential of stem cells early on. He is well known for his surgical skills, and recognizing new opportunities to advance the efficacy of health care treatments. One of the most promising breakthroughs toward that end is the acceleration of stem cell discoveries over the past 20 years.
Dr. Hoyos recognized the potential of these remarkable, undifferentiated cells, capable of  self-reinvention when called upon to take on the functions of other cells in the body when needed, giving rise to a new field of vision for the future of surgical and aesthetic protocols, and the future of medicine altogether. Dr. Hoyos adapts the healing  and restorative capabilities of stem cells  to the aesthetic procedures he performs—including fat grafting and fat transfer—and  has successfully performed assisted stem cell fat transfer procedures for patients looking to restore volume in the facial area that is lost in the natural aging process.
Dr. Hoyos continues to identify new opportunities in innovative medical technology that can improve the quality of patients’ lives.  After adopting and mastering  Vaser ultrasonic liposuction technology, also known as liposelection (an alternative to traditional liposuction) he later developed the Vaser Hi Definition Lipoplasty (VHD) procedure.
Dr. Hoyos founded Stem Lab, a biotechnology company based in Bogotá, to further the development of stromal stem cells derived from adipose tissue. He continues to develop and refine these techniques, while exploring new applications for HD and other emerging technologies  in the field of aesthetic  surgery.
He is an accomplished sculptor, painter, medical book illustrator and author. of several books focusing on high definition body sculpting and advanced lipoplasty techniques. Dr. Hoyos is certified by the Colombian Society of Plastic Surgery, (SCCP) and the  International Confederation of Plastic Reconstructive and Aesthetic Surgery (IPRAS).
