sends news that researchers from the University of Cambridge have made a breakthrough in the production of human pluripotent stem cells
. The goal when developing this kind of stem cell is to have them as early in the cell's lifecycle as possible, so that they're more like true embryonic stem cells and can fulfill whatever role is needed. But all of them made so far are advanced slightly down their developmental pathway. The new work, published in the journal Cell
), has found a way to "reset" the cells by introducing two genes
that induce a developmental "ground state."
