Scientists revise the current textbook knowledge about gastrulation, the formation of the basic body plan during embryonic development. Their study in mice has implications for cell replacement ...

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, ...

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 ...

At the earliest stages of human embryonic development, a small collection of cells known as human embryonic stem cells (hESCs) orchestrates growth and differentiation, eventually giving rise to highly ...

When the zygote, or the fertilised egg, starts to develop, the soon forming inner cell mass, a cluster of cells that will eventually develop into the individual, retains its pluripotent stem cell ...
