The reprogramming of differentiated adult cells into induced pluripotent stem (iPS) cells is accomplished by the expression of a small number of key genes. This is typically done by introducing DNA either by transfection or with viral vectors. Current methods,...

In the RNA world hypothesis, RNA based biological life can exist without the need for DNA and proteins to store information, make decisions, and in general, control cells. In 1998, the discovery that small RNAs can play important roles in controlling cells...

One hurdle facing the use of lab-grown stem cells for therapeutic or experimental purposes is the accumulation of genetic abnormalities over time. The nature of these changes varies, but some may affect therapeutic usefulness and many mirror changes seen in...

Canadian scientists have discovered that stem cells intentionally damage their own DNA in order to regulate development. The breakthrough findings clear up the mystery of how cell death proteins actually promote cell differentiation and cell development. The study,...
