1st human to human ‘reprogrammed’ stem cells transplant done

In a world-first transplant, a Japanese man in his 60s has become the first person to receive cells derived from induced pluripotent stem (iPS) cells donated by another person. iPS cells are created by removing mature cells from an individual and “reprogramming” them back to a premature embryonic state to develop them into desired cell type useful for treating a disease.
