TheEffectsofEthanolonZebrafishDevelopment
Introduction:The early stages of zebrafish, Danio rerio development are characterized by meroblastic dicoidal cleavage. Initially cell division only occurs in the blastodisc, which is a thin region on the animal cap of the egg. This blasotdisc contains all of the egg's cytoplasm and organelles, the rest of the egg is filled with yolk. After about 10 cell divisions the midblastula transition begins and t......阅读全文
