An unexpected link has been found between the metabolic pathways that produce energy for embryo growth, and the cellular signalling systems that regulate cell specialization and movement during early ...

Researchers have identified the origin of cardiac cells using 3D images of a heart forming in real-time, inside a living mouse embryo. Researchers at UCL and the Francis Crick Institute have, for the ...

Five zebrafish embryos in a tiny drop of water. The yolk sac is clearly visible, with the first two cells located at its tip. Hair, nails, and horns, all made up of keratin, are some of the hardest ...

Animal embryos undergo tissue flows and folding processes, involving mechanical forces, that transform a single-layered blastula (a hollow sphere of cells) into a complex multi-layered structure known ...

The role of tissue that forms between the head and trunk of a fly embryo has been unclear. It turns out that it absorbs forces when nearby cells move and divide. An early fruit-fly embryo comprises a ...

Small fold – big role: A tissue fold known as the cephalic furrow, an evolutionary novelty that forms between the head and the trunk of fly embryos, plays a mechanical role in stabilizing embryonic ...
