Objective To investigate the relationship between the first polar body morphology of oocyte and the zygote morphology in pronucleus stage, embryo quality in cleavage stage.
目的 探讨卵细胞第一极体形态与原核期受精卵形态、卵裂期胚胎质量的关系。
By combining with the author’s own research work, the progresses of study on sperm egg identification, acrosomal reaction, cortical reaction, and formation of male and female pronucleus in decapod crustacean are reviewed in the paper.
结合作者近期的研究工作，从精卵识别、顶体反应、皮层反应、雌雄原核的形成和结合等方面综述了近年来十足类甲壳动物受精细胞学方面的研究成果，并展望了这一领域的研究与应用前景。
Methods: All embryos with non-pronucleus (0PN), a single pronucleus (1PN), a number of pronucleus (≥3PN) and 2 pronucleus delaying development in cleavage stage (2PN) were cultured into blastula by the sequential method.
方法:通过囊胚序贯培养法将无原核(0PN)、单个原核(1PN)、多个原核(≥3PN)和卵裂期发育延缓的2原核(2PN)废弃胚胎培养至囊胚期。
To obtain the fertilized eggs with clear male pronuclei is the key of success .
