Scientists turn back time in living mice

|By:, SA News Editor

On Wednesday, a study published in the journal Nature, showed scientists were able to reprogram mature cells in mice, effectively "turning back the hands of time" (to use Bloomberg's expression), and forcing the cells to revert to a form of stem cell which can differentiate into other kinds of cells.

Incredibly, the reprogrammed induced pluripotent stem cells ((iPS)) showed more potential — in terms of their ability to change into different cell types — than either embryonic stem cells or normal iPS cells.

The idea is that scientists may one day be able to regenerate damaged tissue inside a patient's body. Previously, researchers had only demonstrated the ability to forcibly reprogram the cells in petri dishes. (more here)
