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 ...

Fluorescence imaging of a pre-gastrula zebrafish embryo, showing DNA (gray) and cell structure (magenta). The video moves through different depths of the embryo, showing chromosome formation, ...

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 ...

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 ...

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 ...

Hair, nails, and horns, all made up of keratin, are some of the hardest and most resilient structures in animals. Inside zebrafish cells, keratin plays a distinct role, giving them the strength they ...
