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 ...

A team of scientists has identified an unexpected embryonic "starting point" for several brown-fat depots: a small cell niche around the dorsal aorta. Using a combination of time-controlled genetic ...

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 ...

Biologists have identified the specific region in vertebrates where adult blood stem cells arise during embryonic development. The researchers say their time-lapse imaging of the process, by which ...

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 ...

Dr Jitesh Neupane discusses his hematoids model and opportunities to study childhood blood disorders and future stem cell therapies.

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

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 ...
