    Scientists Discover How to Control Fate of Stem Cells

    ScienceDaily (June 24, 2011) — Scientists from the Genome Institute of Singapore (GIS), an institute of the Agency for Science, Technology and Research (A*STAR), in collaboration with the Cancer Science Institute of Singapore (CSI), have discovered how the body uses a single communication system to decide the fate of stem cells. The study, published in the scientific journal PLoS Genetics on 23rd June 2011, paves the way for the development of new methods of stem cell therapy with fewer side effects.

    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.

    I would think so.

    In my opinion (not that it counts for much ), this kind of science will drive the 2nd and 3rd generation cures for SCI. It is a very important line of basic science.

    There are a number of similar lines of research to this. Check out the work being done by Stefano Pluchino at Cambridge University, UK and also John Gensel at Ohio State University, US.
