Histones and the mystery of cell proliferation

Before cells divide, they create so much genetic material that it must be wound onto spools before the two new cells can split apart. These spools are actually proteins called histones, and they must multiply at the same ...

The developmental on-switch

German researchers have demonstrated for the first time why the molecular cocktail responsible for generating stem cells works. Sox2 and Oct4 are proteins whose effect on cells resembles that of an eraser: They remove all ...

Japan govt approves stem cell clinical trials

Japan's government on Friday gave its seal of approval to the world's first clinical trials using stem cells harvested from a patient's own body.

Japan experts to OK animal-human embryos test: reports (Update)

Proposed experiments with animal-human embryos cleared the first regulatory hurdle Tuesday, reports said, as Japanese scientists seek permission for tests that could see human organs produced inside the growing body of an ...

Rewinding development: A step forward for stem cell research

Scientists at the Danish Stem Cell Center, DanStem, at the University of Copenhagen have discovered that they can make embryonic stem cells regress to a stage of development where they are able to make placenta cells as well ...
