Two proteins safeguard skin stem cells

Our skin renews, heals wounds, and regenerates the hair that covers it thanks to a small group of stem cells. These cells continually produce new ones, which appear on the skin surface after a few days. A study led by ICREA ...

Defining what it means to be a naive stem cell

Whitehead Institute scientists have created a checklist that defines the "naive" state of cultured human embryonic stem cells (ESCs). Such cells can mature into almost any cell type and more closely resemble the unique molecular ...

New procedure allows long-term culturing of adult stem cells

A new procedure developed at Massachusetts General Hospital (MGH) may revolutionize the culturing of adult stem cells. In their report that has been published online prior to its appearance in the August 6 issue of Cell Stem ...

Stem cell technique makes sperm in a dish

Scientists in China have finally succeeded in creating functioning sperm from mice in the laboratory. To accomplish this feat, the researchers coaxed mouse embryonic stem cells to turn into functional sperm-like cells, which ...

Researchers transform common cell to master heart cell

By genetically reprogramming the most common type of cell in mammalian connective tissue, researchers at the University of Wisconsin-Madison have generated master heart cells—primitive progenitors that form the developing ...
