Researchers identify metabolic pathway essential for embryo development, thus extending knowledge of how embryos form and how to develop a safer drug regimen for pregnant women Tokyo - Much has been ...

Prior to gastrulation the mouse embryo exists as a symmetrical cylinder consisting of three tissue layers. Positioning of the future anterior-posterior axis of the embryo occurs through coordinated ...

NEW YORK – New lab techniques have provided the first good look at a crucial but mysterious stage in the development of human embryos, scientists reported Wednesday. The researchers said follow-up ...

The beating of the heart inside an embryo doesn’t just circulate blood through the developing creature, it also triggers the formation of blood stem cells, the cells that give rise to all other forms ...

In a discovery that will revolutionize research into the causes of early miscarriage, infertility and the study of early human development - an international team of scientists led by Monash ...

Aldehyde dehydrogenase (ALDH) are a group of NAD(P) +-dependent enzymes involved in the biosynthesis of retinoic acid as well as the metabolism of amino acid, fatty aldehydes, ethanol and ...

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development - including the ...

The physical forces exerted by a heart beat and the blood flow it produces trigger the formation of new blood cells, according to two studies published today (May 13) in Nature and Cell. Zebrafish ...

How far should scientists be allowed to go in creating things that resemble primitive human brains, hearts, and even human embryos? That's the question being asked by a group of Harvard scientists who ...

Researchers showed that the mevalonate pathway is essential for embryonic development by promoting primitive streak formation, a key landmark for establishing embryo symmetry and gastrulation. The ...
