It was only 10 years ago that Shinya Yamanaka, M.D., Ph.D., discovered how to convert a person’s skin cells into stem cells by tweaking just four genes. The historical breakthrough landed Dr. Yamanaka the 2012 Nobel Prize in Physiology-Medicine, because it meant that patients could be their own stem-cell donors. Known as induced pluripotent stem cells (iPSC), they are now being used to develop powerful therapies and drug-screening tools including those for the retina.
To the delight of nearly 300 retinal researchers from around the world attending the FFB-funded RD2016 meeting, September 19-24 in Kyoto, Japan, Dr. Yamanka discussed his early clinical trial for iPSC-derived retinal pigment epithelial (RPE) cells for a 78-year-old woman with advanced wet age-related macular degeneration (AMD). The study met its main goal – safety – and he and his collaborator, Masayo Takahashi, M.D., Ph.D., are planning to treat additional patients in the near future.
