Does blood formation in mammalian embryos and adults have separate origins or a common source? The most recent investigations into the question add a further chapter to this long-running story. You ...

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 ...

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 ...

Research improves upon a popular experimental model of mammal development and in doing so, reveals more of the inner workings of a critical period during the formation of an embryo. Research from Ph.D ...

All blood vessels originate from the same precursor cells in early embryos. So how do those precursors decide whether to contribute to arteries or veins? Studies of zebrafish bring us closer to the ...

"The thing that just wows me about this is that blood stem cells, when they form in the embryo, form in the wall of the main vessel called the aorta. And they basically pop out of this aorta and go ...

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 ...

WHEN the embryonic heart begins to beat, it kick-starts the production of blood from cells lining the growing aorta, two independent research teams have shown. As the heart starts pumping a primitive ...

(PhysOrg.com) -- Biologists have long wondered why the embryonic heart begins beating so early, before the tissues actually need to be infused with blood. Two groups of researchers from Children's ...

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 ...
