Fish developmental biology
Fish embryos go through a process called mid-blastula transition which is observed around the tenth cell division in some fish species. Once zygotic gene transcription starts, slow cell division begins and cell movements are observable. During this time three cell populations become distinguished. The first population … See more The development of fishes is unique in some specific aspects compared to the development of other animals.

WebDevelopmental Biology 3230. Cleavage refers to the stereotyped pattern of early mitotic divisions that divides up the large volume egg cytoplasm. The early zygote is unique in being so large. Most cells undergo a period of growth between cycles of mitosis, but this is not true for early cleavage stage blastomeres. WebTo explore ExM in the context of zebrafish developmental biology, we investigated the morphology of nuclei at an early embryonic stage. We used embryos from a fish line where EGFP is fused to histone-2B (details are provided in Methods), and we used anti-lamin B and anti-tubulin to visualize the nuclear boundary and microtubules, respectively ...
