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 ...

LONDON – Scientists have used human embryonic stem cells to create an embryo-like research model to help them study some of the earliest stages of human development. The model overcomes some of the ...

Researchers offer a phylogenetic and ontogenetic overview of the primitive streak and its role in mediating amniote (vertebrate animals that develop on land) gastrulation, and discuss the implications ...
