Identical twins, not-so-identical stem cells
A brand new twin examine sheds gentle on epigenetic patterns in stem cells. Credit score: © pololia / Fotolia Salk scientists and collaborators have make clear a long-standing query about what results in variation in stem cells by evaluating induced pluripotent stem cells (iPSCs) derived from an identical twins. Even iPSCs created from the cells of twins, they discovered, have vital variations, suggesting that not all variation between iPSC traces is rooted in genetics , because the twins have an identical genes. As a result of they will differentiate into nearly any cell kind within the physique, stem cells have the potential for use to create wholesome cells to deal with quite a few ailments. However stem cells are available two varieties: embryonic stem cells (ESCs), that are remoted from embryos, and iPSCs, that are created within the lab from grownup cells which can be reprogrammed utilizing mixtures of signa...
