Stem Cell Cocktail for Us Old Folks

'Rejuvenated' stem cells coaxed from centenarian. Scientists said Tuesday they had transformed age-worn cells in people over 90 -- including a centenarian -- into rejuvenated stemcells that were "indistinguishable" from those found in embryos.

The technical feat, reported in the peer-reviewed journal Genes & Development, opens a new path toward regenerative medicine, especially for the elderly, the researchers said.

Lemaitre and colleagues decided to alter the standard genetic starter kit used to generate adult stemcells by adding two new ingredients -- known as transcription factors -- called NANOG and LIN28. MedicalXpress
