Signals that make early stem cells identified

Stem cells work throughout our lives as a sort of handyman, repairing damaged tissues and renewing some normal ones, like the skin we shed. Scientists have come to understand much about how stem cells function when we are ...

Forks colliding: How DNA breaks during re-replication

Leveraging a novel system designed to examine the double-strand DNA breaks that occur as a consequence of gene amplification during DNA replication, Whitehead Institute scientists are bringing new clarity to the causes of ...

Baby cells learn to communicate using the lsd1 gene

We would not expect a baby to join a team or participate in social situations that require sophisticated communication. Yet, most developmental biologists have assumed that young cells, only recently born from stem cells ...

Stem cell progeny tell their parents when to turn on

(Phys.org) —Stem cells switch off and on, sometimes dividing to produce progeny cells and sometimes resting. But scientists don't fully understand what causes the cells to toggle between active and quiet states.

Shining stem cells reveals how our skin is maintained

All organs in our body rely on stem cells in order to maintain their function. The skin is our largest organ and forms a shield against the environment. New research results from BRIC, University of Copenhagen and Cambridge ...
