Relations between a cytoplasmic species specificity and the duration of cleavage cycles were investigated by reciprocal injections of egg cytoplasm. Xenogenic cytoplasm induces an early or delayed cleavage of the recipient egg depending on the chronological specificity of the injected cell cytoplasm. Activity of the so-called cleavage timing system (CTS) was first detected in the cytoplasm of maturing oocytes at the stage of germinal vesicle breakdown (GVBD). This specific cytoplasmic property was not dependent on the maturation promoting factor (MPF). Relations between the CTS and other cytoplasmic components which are known to induce cleavage are discussed.
通过对卵细胞质进行相互注射，研究了细胞质物种特异性与卵裂周期持续时间之间的关系。根据注射细胞质的时间特异性，异种细胞质会诱导受体卵的早期或延迟卵裂。所谓的卵裂时间系统（CTS）的活性首先在生发泡破裂（GVBD）阶段的成熟卵母细胞的细胞质中被检测到。这种特定的细胞质特性不依赖于成熟促进因子（MPF）。本文讨论了CTS与其他已知可诱导卵裂的细胞质成分之间的关系。
