There is a great rush going on in the Scientific community since the discovery of how to reprogram cells to be stem cells.
This ability, which exists in nature in reptiles regrowing their limbs, is achieved by resetting the expression profile of a cell. A Cell specializes in its function as it derives from stem cells status. But they never really lose the capacity to revert back to a more primary state.
Therefore reprogramming cells, thinking of them as state machines, has become a major thrust in the biological sciences. By applying a distress signal, local skin cells have been show to re-boot themselves as stem cells. They do so by rewiring the expression filters, almost removing them. From there on reprogramming down the tree, a colony of cells can regrow limbs. Which is pretty handy and neat. A new industry of bio-software is being born.
The great rush to the Stem Cells is on!
