Simple chemical procedure augments therapeutic potential of stem cells
Adult stem cells resemble couch potatoes if they hang out and divide in a dish for too long. They get fat and lose key surface proteins, which interferes with their movement and reduces their therapeutic potential. Now, via ...

Novel genetic screens provide panoramic views of cellular systems
Despite the rise of systems biology, many geneticists continue to probe genes in isolation. They even use cutting-edge RNA interference (RNAi) technology to knock down one gene at a time. This approach often yields a narrow ...

Being a control freak aids dividing cells
Micromanagers may generate resentment in an office setting, but they get results in your body. New data indicate that a dividing cell takes micromanagement to the extreme, tagging more than 14,000 different sites on its proteins ...
