~ 3 H-胸腺嘧啶核苷脉冲15分钟后DNA合成的放射自显影标记模式表明，小鼠胚胎在2-和16-细胞期之间的细胞生命周期缺乏G1期。在桑椹胚和胚泡阶段，80%的细胞被15分钟的3 H-胸苷脉冲标记，表明GI期非常短，在这些发育的后期可能不存在。在两细胞期之后，G2期非常短。
The autoradiographic labeling patterns for DNA synthesis after a 15 min pulse of3H-thymidine show that the cell life cycles for mouse embryos between the two- and 16-cell stages lack a G1 period. During morulae and blastocyst stages 80 % of the cells are labeled by a 15 min pulse of3H-thymidine, demonstrating that the GI period is very short and possibly absent during these later stages of development. Subsequent to the two-cell stage, the G2 period is very short.
