Advances in genetic and computational tools have enabled researchers to study complex networks of gene expression in individual cells, and the patterns of gene expression in a population of cells ...

A new discovery by researchers challenges our current understanding of gastrulation, the most important stage of early embryonic development. When the zygote, or the fertilised egg, starts to develop, ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

Researchers uncovered key networks that simultaneously control pluripotency and readiness for cell death (apoptosis), helping to ensure optimal conditions for embryonic development. The study's ...

Pulmonary arterial hypertension (PAH) is a rare condition that's difficult to treat. The hallmarks of the disease—narrowing of the arterioles and capillaries that deliver blood to the lungs—force the ...
