Abstract

The development of rete testis in the rat, rabbit and guinea pig foetuses has been studied, as well as the influence of prolactin and thyrotropin on differentiation of its cells. It was shown that the rete testis tubules, as well as the seminiferous tubules develop from sex cords, which were derived from coelomic epithelium cells and gonocytes. The development of seminiferous tubules and rete testis was described at various stages of prenatal ontogenesis. Thyrotropin and prolactin exert different effects on differentiation of the rete testis cells: the former increases the mitotic activity of gonocytes and the latter increases that of epithelial cells and enhances degenerative processes in primary germ cells.

摘要

对大鼠、兔和豚鼠胎儿睾丸网的发育以及催乳素和促甲状腺激素对其细胞分化的影响进行了研究。结果表明,睾丸网小管以及生精小管均由性索发育而来,性索源自体腔上皮细胞和生殖母细胞。描述了产前个体发育不同阶段生精小管和睾丸网的发育情况。促甲状腺激素和催乳素对睾丸网细胞的分化有不同影响:前者增加生殖母细胞的有丝分裂活性,后者增加上皮细胞的有丝分裂活性并增强原始生殖细胞中的退化过程。
