Protein involved in nematode stress response identified

When humans experience stress, their inner turmoil may not be apparent to an outside observer. But many animals deal with stressful circumstances—overcrowded conditions, not enough food—by completely remodeling their ...

The source of stem cells points to two proteins

Mammalian embryos are unlike those of any other organism as they must grow within the mother's body. While other animal embryos grow outside the mother, their embryonic cells can get right to work accepting assignments, such ...

Mechanism for turning skin cells into blood stem cells uncovered

Researchers have succeeded in converting human skin cells into blood stem cells in an international collaboration project. "This is a first step on the way to generating fully functional blood stem cells in a petri dish which, ...

Honeybee protein keeps stem cells youthful

An active protein component of royal jelly helps honeybees create new queens. Stanford researchers have identified a similar protein in mammals, which keeps cultured embryonic stem cells pluripotent.

Maintaining the unlimited potential of stem cells

Embryonic stem cells (ESCs) are the very definition of being full of potential, given that they can become any type of cell in the body. Once they start down any particular path toward a type of tissue, they lose their unlimited ...
