'Roadmap' tracks trajectories of embryo development

Scientists have mapped out the key molecular changes that orchestrate how embryonic mouse cells differentiate into the diverse cell types that will ultimately form all the different tissues and organs of the adult animal.

Study identifies key regulator of cell differentiation

Embryonic stem cells and other pluripotent cells divide rapidly and have the capacity to become nearly any cell type in the body. Scientists have long sought to understand the signals that prompt stem cells to switch off ...
