The presence of the cytostatic factor found by Masui and Markert (1971) in the cytoplasm of oocytes and eggs of Rana pipiens was verified in the cytoplasm and mature inactivated eggs of the common frog Rana temporaria and sevryuga Acipenser stellatus. The cytoplasm was injected to the embryos of the same species at different phases of the first cleavage division in the animal region of one of the two blastomeres. The injection of cytoplasm did not cause the arrest of cleavage divisions. Many embryos proceeded to gastrulation. The cytoplasm of maturing oocyte and mature egg in the common frog and sevryuga, unlike in R. pipiens, has no cytostatic effect.
在泽蛙卵母细胞和卵的细胞质中发现的细胞静止因子（由Masui和Markert于1971年发现），在欧洲林蛙和星鲟的细胞质以及成熟失活卵中得到了证实。将细胞质注射到同一物种胚胎的两个卵裂球之一动物极区域第一次卵裂分裂的不同阶段。细胞质注射并未导致卵裂分裂停止。许多胚胎进入了原肠胚形成阶段。与泽蛙不同，欧洲林蛙和星鲟成熟卵母细胞和成熟卵的细胞质没有细胞静止作用。
