Distinct chromatin patterns linked to heart development

(Phys.org) -- New research at the Hebrew University of Jerusalem sheds light on pluripotency—the ability of embryonic stem cells to renew themselves indefinitely and to differentiate into all types of mature cells. ...

A gene which is essential for stem cells' capabilities to become any cell type has been identified by researchers at the Hebrew University of Jerusalem and the University of California, San Francisco.

MIT biologists have discovered that the organization of DNA's packing material plays a critical role in directing stem cells to become different types of adult cells.

(HealthDay) -- Cells that normally form scar tissue after a heart attack can be reprogrammed into functional heart cells in mice, according to an experimental study published online April 18 in Nature.

As an embryo develops, different genes are turned on in different cells, to form muscles, neurons and other bodily parts. Inside each cell's nucleus, genetic sequences known as enhancers act like remote controls, ...
