Advanced mouse embryos grown outside the uterus

To observe how a tiny ball of identical cells on its way to becoming a mammalian embryo first attaches to an awaiting uterine wall and then develops into nervous system, heart, stomach and limbs: This has been a highly-sought ...

Research illuminates embryonic stem cell fate

USC postdoctoral researcher Xi Chen knows that you have to break a few eggs in order to grow chicken stem cells. His work on maintaining embryonic stem cells (ESC) from chicken eggs provides insight into stem cell pluripotency ...

New-found molecular signature keeps key genes ready for action

During development, scores of molecular signals prod cells to take on specialized identities and functions. In response to some of these signals, the cellular machinery awakens specific genes called 'immediate early genes' ...

Chromatin remodelers never rest to keep our genome open

Chromatin remodelers are needed to take nucleosomes away from DNA in order to make room for transcription factors to bind, and regulate the activity of our genes. It has been unclear how dynamic this process is. Researchers ...

High-speed model for the fight against SARS-CoV2

To contain the SARS-CoV2 coronavirus and slow the spread of infections and the rising death toll, researchers and health professionals around the world are rapidly developing vaccines and medical drugs. But before these can ...
