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 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 ...
