During the first 72 hours in particular, extracellular vesicles—nanoparticles enclosed in cell membranes—play a significant role in the embryonic development of zebrafish. This is the result of a ...

Research shows how the curved shape of a zebrafish egg sets cell division timing, gene activation, and early cell fate specification.

Researchers have published an atlas of zebrafish development, detailing the gene expression programs that are activated within nearly every cell type during the first five days of development, a ...

Researchers have uncovered how egg cells prepare for the creation of life. Their work reveals the secrets of the Balbiani body (Bb), a remarkable structure that organizes essential molecules to guide ...

How can we reliably and objectively characterize the speed and various stages of embryonic development? With the help of artificial intelligence! Researchers present an automated method. Animal ...

Animal embryos go through a series of characteristic developmental stages on their journey from a fertilized egg cell to a functional organism. This biological process is largely genetically ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early ...
