雌激素对小鸡输卵管卵白分泌部的细胞分化和管状腺形成的诱导作用

雌激素对小鸡输卵管卵白分泌部的细胞分化和管状腺形成的诱导作用 ESTROGEN-INDUCED CYTODIFFERENTIATION AND FORMATION OF TUBULAR GLAND IN THE MAGNUM OF THE CHICK OVIDUCT 温璋文 first-author 曾翠瑜 赵克斌 谭先琴 肖静宁 对未成熟雌性小鸡给予雌激素后,观察到随着雌激素注入量的增加,输卵管随之增重,输卵管各段分化也随着明显起来,卵白分泌部颗粒出现,管状腺形成。停止注射雌激素后,输卵管重量逐渐减轻,腺体逐渐萎缩,分泌颗粒消失。再注射雌激素,管状腺细胞颗粒重新出现,腺体又膨胀起来,输卵管又迅速增重。实验证明:鸡输卵管卵白分泌部上皮细胞的分化,管状腺的形成,输卵管管壁的增厚依赖于雌激素的作用。 After administration of exogenous estrogen to the immature chicken, it was observed that the weight of the chick oviduct increased with the increase in the amount of injected estrogen. The differentiation in different portions of the chick oviduct became apparent. The granules appeared and the tubular glands were formed in the magnum. After withdrawal of injection of estrogen, the weight of the oviduct progressively decreased, the glands gradually atrophied and the secretory granules disappeared When estrogen was rejected to the chicken, the granules in the cells of the tubular glands appeared again, the glands intumesed and the weight of the oviduct increased rapidly. Our experiment showed that the differentiation of the surface epithelial cell of the chick oviduct magnum, the formation of the tubular glands and the thickening of the oviduct wall all depended upon the effect of estrogen injected. 1986-03-01 2021-04-01 3
