Stem cells’ powers of self-renewal, immortality and potential for medicine inspire those who study them. But progress toward understanding them has been slow — it took 20 years just to figure out how to grow embryonic stem cells in the laboratory. More recently, though, molecular techniques have enabled swift movement on two fronts. Researchers are starting to see how stem cells can replenish their numbers while giving rise to specialized cells. Others are learning how to turn adult skin cells into cells more like their embryonic ancestors. These advances offer hope ...Published: September 13th, 2008; Vol.174 #6 -

GOTHENBURG, Sweden —Woody Allen might have coined it: the law of conservation of fragility. If part of a biological network gets stronger, some other part is bound to get weaker, new research shows. Its total fragility never gets better or worse, it just stays the same. Rather than being a statement of pessimism, this new law of conservation offers hope for finding better drug targets to treat diseases such as diabetes, heart disease and cancer, according to research presented by Hans V. Westerhoff, systems biologist at the Manchester Centre for Integrative Systems Biol...Published: Monday, August 25th, 2008Found in: Genes & Cells

As researchers develop ways of reprogramming adult cells, such as skin cells, to have the same flexibility as embryonic stem cells, this new test shows that the reprogrammed stem cells are truly capable of becoming any cell in the body.Published: Sunday, August 24th, 2008Found in: Biomedicine and Body & Brain
