KOBE, Japan - Haruko Obokata, a scientist at Riken's Center for Developmental Biology in Kobe, speaks at a press conference in Kobe, Hyogo Prefecture, on Jan. 28, 2014, on "stimulus-triggered acquisition of pluripotency," or STAP, a method of generating pluripotent cells. A team of scientists led by Obokata has discovered, in research conducted by scientists at the state-backed Riken institute and Harvard University, that by simply exposing body cells to acidic liquids, the cells can be reprogrammed to grow into any type of mature tissue.
