World's 1st transplant involving donor iPS cells
NHK -- Mar 29
Groups of Japanese researchers say they have successfully transplanted iPS cells derived from a donor into a patient suffering from a serious eye disease.

The one-hour operation was performed on Tuesday at Kobe City Medical Center General Hospital. It was conducted by project leader Masayo Takahashi from a RIKEN research lab, and teams from Kobe City Medical Center General Hospital, Kyoto University and Osaka University.

They transplanted retinal tissue made from donor iPS cells into a man in his 60s with a disease called age-related macular degeneration.

The tissue was created from a special kind of iPS cell less likely to be rejected immunologically. A group led by Kyoto University Professor Shinya Yamanaka created this type of cell from people with a special kind of immunity. The university preserves such iPS cells by freezing them. These tissues can be multiplied almost indefinitely once they are unfrozen and cultured.
