How does a tiny cluster of cells become an embryo with a head, trunk, and tail? And how do thousands of genes coordinate this development? A new imaging method makes it possible to visualize the ...

Researchers confirm using zebrafish that if a certain gene is not excluded when vertebrate embryos are developing, the notochord will not elongate properly, resulting in a shortened form. Can a single ...

Scientists headed by a team at the Chan Zuckerberg Biohub San Francisco (CZ Biohub SF) reported on the development of Zebrahub, a dynamic, state-of-the-art atlas of zebrafish embryonic development.

Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying ...

Study finds that large embryo cells divide step by step using a mechanical ratchet system, challenging the textbook idea of a ...

When early cartographers undertook perilous expeditions to map unknown corners of the world with sextants, compasses, and hand-drawn diagrams, it’s unlikely they imagined that someday anyone with an ...

This white sphere on a background of forest green is the eye of an embryonic zebrafish. The eye of an adult zebrafish is about 2.3 millimeters across, or roughly nine times smaller than your thumbnail ...

Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize itself into a complex organism. It underpins the diversity in the animal ...

Can a single protein-encoding gene determine whether a vertebrate embryo develops normally? Yes, according to Osaka Metropolitan University researchers, who found that suppression of Pcdh8 is ...
