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, ...

In their publication in Science, Professor Guojun Sheng (Kumamoto University, Japan), Professor Alfonso Martinez Arias (Universidad Pompeu Fabra, Spain) and Professor Ann Sutherland (University of ...

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 ...

How do cells turn into organs? During embryonic development, three germ layers form, known as the endoderm, the mesoderm, and the ectoderm. These germ layers give rise to different parts of the ...

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 ...
