EarlydevelopmentofprimarymotorneuronsandsomitesinZebrafishEmbryos
Background:Zebrafish,or the teleost fish Danio rerio,is a rapidly developing organism that is apopular species for studying vertebrate development. Cleavage in the Zebrafish only occurs inthe blastodisc,a region of cytoplasm in the animal cap of the egg. This type of meroblasticcleavage is called discoidal. Cell divisions are rapid in the zebrafish,with divisions takingabout fifteen minutes each. Gastrulation is usua......阅读全文
