At metaphase of the first cleavage, the UV-irradiated female nucleus did not form chromosome, but became a dense chromatin body ( DCB), which did not participate in the karyokinesis at anaphase of the first cleavage. 经紫外线照射的卵核在第1卵裂中期没能形成染色体,而是形成1个浓缩的染色质小体,没有参与第1卵裂后期的核分裂。
The rate of maturation& cleavage and embryo development potential were judged through applying nucleus staining method and embryo transfer technology et al, and evaluated statistically. 应用胞核染色、胚胎移植等技术判定并统计成熟率、卵裂率和胚胎发育潜能。
After cleavage, Notch-IC is translocated to the nucleus, where it interacts with RBP-J ( or CBF1) and modulates gene expression. 分离以后,Notch-IC就转移进入核内,与RBP-J(在哺乳动物中又称CBFl)相互作用并调节基因的表达。
