Stress May Naturally Make Stem Cells of Mature Cells

Check it out, even if the acid bath proposal went downhill, this seems to have more support.

Stress or injury may naturally prompt mammals to make “extraordinary” stem cells out of certain “ordinary” mature cells via dedifferentiation.
Three strong papers suggesting this were quietly published within weeks of the controversial Nature “acid bath” work, where a team from Japan’s Riken Institute, and the US’s Harvard University, reported dedifferentiating neonatal mouse spleen cells into stem cells by stressing them, artificially in a dish, with coffee-mild acid.
Confidence in the “acid” work has hit a new low. It has not been repeated. A Riken investigation found lead author Haruko Obokata committed two acts of falsification and fabrication that may have crippled the papers—and may prompt retraction. (See Bioscience Technology stories on “acid bath” developments.)
But the other three studies – conducted by unrelated teams on mammalian stomach, trachea, and kidney—have generated no controversy. Two drew raves from the Faculty of 1000.
