The Yin and Yang of stem cell quiescence and proliferation

Not all adult stem cells are created equal. Some are busy regenerating worn out or damaged tissues, while their quieter brethren serve as a strategic back-up crew that only steps in when demand shoots up. Now, researchers ...

The proteins ensuring genome protection

Researchers from the University of Geneva (UNIGE), Switzerland, have discovered the crucial role of two proteins in developing a cell 'anti-enzyme shield'. This protection system, which operates at the level of molecular ...

Scientists create stable, self-renewing neural stem cells

In a paper published in the April 25 early online edition of the Proceedings of the National Academy of Sciences, researchers at the University of California, San Diego School of Medicine, the Gladstone Institutes in San ...

Looking at cancer progression as evolutionary process

Two University of Oregon biologists have launched an ambitious, highly focused effort to identify genetic changes that occur from the formation of a single mutation to full-fledged cancer.

Researchers develop safer way to make induced pluripotent stem cells

Researchers at Johns Hopkins have found a better way to create induced pluripotent stem (iPS) cells -- adult cells reprogrammed with the properties of embryonic stem cells -- from a small blood sample. This new method, described ...
