为了探究嗜银细胞在黑龙江林蛙胃肠道胚后发育过程中的演变规律,试验采用Grimelius法对黑龙江林蛙胚后发育各时期胃肠道中嗜银细胞的发生过程进行了研究。结果表明:嗜银细胞最早出现在第38期胃黏膜上皮之间,小肠中嗜银细胞最先出现在第42期,随着胃肠道发育的逐渐完善,其分布的位置及形态也有所不同,嗜银细胞的分布位置由初始时的上皮细胞之间到腺泡上皮之间变化,细胞形态也由闭合型细胞到开放型细胞转变。推测嗜银细胞的发生时间与蝌蚪的进食及生长发育的需要有关,其分布位置和形态与嗜银细胞的功能有关。
In order to explore the evolvement rule of argyrophilic cells in the post-embryonic development of gastrointestinal tract of Rana chensinensis in Heilongjiang Province, Grimelius method was used to study the occurrence of argyrophilic cells in the gastrointestinal tract during embryo development of Heilongjiang Rana chensinensis. The results showed that the argyrophilic cells first appeared in the 38th gastric mucosa epithelium, and the argyrophilic cells in the small intestine first appeared in the 42nd stage. With the development of the gastrointestinal tract gradually improved, the location and the shape of the argyrophilic cell differed The distribution of argyrophilic cells changed from the initial epithelial cells to the acinar epithelium, and the morphology of the cells changed from closed cells to open cells. It is speculated that the occurrence time of argyrophilic cells is related to the need of feeding and growth of tadpoles, and its location and morphology are related to the function of argyrophilic cells.
