 In 2012 Lanza and a team led by Kwang-Soo Kim at Harvard University reported a method for generating induced pluripotent stem (iPS) cells by incubating them with proteins, instead of genetically manipulating the cells to make more of those proteins.Lanza's team at Advanced Cell Technology were able to generate retinal pigmented epithelium cells from stem cells, and subsequent studies found that these cells could restore vision in animal models of macular degeneration.With this technology, some forms of blindness could potentially be treatable.
