Selective silver staining was used to study optimal conditions for demonstration of nucleolus organizer regions (NORs) of chromosomes in early embryogenesis of the laboratory mouse. The NORs were not observable during the first cleavage division. During the second cleavage, 1-7 NORs per metaphase were demonstrable. The time course of NORs demonstration was elucidated from the first cleavage till the 10th day of gestation.
采用选择性银染法研究实验室小鼠早期胚胎发育过程中染色体核仁组织区（NORs）显示的最佳条件。在第一次卵裂期未观察到NORs。在第二次卵裂期，每个中期可显示1 - 7个NORs。阐明了从第一次卵裂到妊娠第10天NORs显示的时间进程。
