It happens in the first hours after fertilization: The cells of the early embryo begin to independently produce proteins, the building blocks for cells and organs. Their own, uniquely composed genetic ...

During the first 72 hours in particular, extracellular vesicles—nanoparticles enclosed in cell membranes—play a significant ...

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.

Just in time for Heart Month, the laboratory of University de Montréal medical professor and CHU Sainte-Justine researcher Rubén Marín‑Juez has unveiled the first comprehensive atlas of coronary ...

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 ...

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 ...

An international study has identified a gene that plays an important role in the development of the human embryo. If it is altered, malformations of various organ systems can result. The gene emerged ...

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 ...
