Científicos de Singapur dan con la manera de controlar el destino de las células madre, sin que se tornen cancerosas.

Dr Kian Leong Lee and his team of scientists studied how a single signaling system known as the Nodal/Activin pathway tells stem cells what cell type they should eventually become. The pathway is able to specify a wide range of eventual cell types, challenging the current belief that chemical signaling systems are highly specific and only control a limited number of outcomes. This discovery is a major step forward for stem cell therapies and personalised medicine; by exploiting this signaling system, scientists will be able to control the eventual fate of a stem cell by simply adjusting the chemical environment of a cell. This method of controlling stem cell differentiation also avoids modifying the genetic material of the cell, a procedure that might lead to the cells becoming cancerous.
