Abstract
Cytophotometrics measures of DNA-Feulgen were realized in normal and delayed implantation blastocysts of the rat. During afternoon of the 5th day of progestation, blastocysts were of two types: those nuclei of which were in G1 gap and those nuclei of which were synthetising DNA. In delayed implantation, blastocyst nuclei were in G1 or G2 gap. Mitosis were rarely seen. After oestrogen injection DNA-synthesis started again. Cell kinetics before ovoimplantation is discussed.
摘要
在大鼠正常和延迟着床的囊胚中进行了DNA - 福尔根的细胞光度测定。在妊娠第5天下午，囊胚有两种类型：一种其细胞核处于G1期，另一种其细胞核正在合成DNA。在延迟着床时，囊胚细胞核处于G1期或G2期。很少见到有丝分裂。注射雌激素后DNA合成再次开始。本文讨论了卵植入前的细胞动力学。
