In A Nutshell Egg geometry drives development: The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller cells at the margin—a size ...

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.

Researchers at the National Institutes of Health have published an atlas of zebrafish development, detailing the gene expression programs that are activated within nearly every cell type during the ...

A cross-department collaboration headed by researchers at Harvard Medical School and Harvard University has witnessed the moment at which cells in the zebrafish embryo heart start beating in unison ...

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 new way embryonic cells divide when conventional mechanisms fail. Cell division underpins all ...

A recent article demonstrated how lymphatics -- which remove waste from the rest of the body -- are also associated with microglia and brain development in zebrafish. During the embryonic stage of ...

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 ...
