Stem cells: A new way to induce pluripotency
Stem cells: A new way to induce pluripotency

An unusual reprogramming phenomenon by which the fate of somatic cells can be drastically altered through changes to the external environment is described in two papers in this week’s Nature.


Haruko Obokata and co-authors demonstrate that mammalian somatic cells can be reprogrammed when stressed by low-pH conditions, and call the phenomenon stimulus-triggered acquisition of pluripotency (STAP).

In a second paper, Obokata and colleagues investigate the nature of STAP cells and suggest that they represent a unique state of pluripotency. The researchers also demonstrate that under pluripotent stem-cell culture conditions STAP cells can be transformed into robustly self-renewing stem cells, similar to embryonic stem cells.
