Boost the levels of a gene called NANOG inside a embryonic stem cell, fuse it with a brain cell and the brain cell converts into a stem cell.

The researchers believe that Nanog, alongside other genes, kicks into action a cascade of complex biological machinery that forces cells back into their simplest state, before they have gone down the path of becoming one of the 200 cell types found in the body.
