大白鼠脾窦的胚胎发生

Erabryogenesis of Splenic Sinuses of Rats

本文观察了大白鼠脾窦内皮细胞胚胎发生中的起源及形态演变过程。脾窦来源于睥脏本身的间充质细胞。最初脾窦为连续型的毛细血管,内皮细胞椭圆形,细胞间可见紧密连接,继之内皮细胞转变成梭形,最后形成长杆状,内皮细胞间呈间断的连接,缺乏连接处出现裂孔,孔处无基膜封闭,内皮外基膜不完整,发育成典型的栅栏状。

This experiment observed the original and the change in its morphology of the splenic sinuses's endothelium of rats in emb ryogenesis.The splenic sinuses were from the mesenchymal cell of spleen. Primarily, the splenic sinuses were continous capillary and endothelium were elliptical,which existed in close connection be-tween them.Farther-more, the endothelium elongated from a spindle shape into a rod-shaped and splits in the place without connction The splits were not closed by basic membrane. The basic membrane of endothelium was not completed.The endothelium diveloped typical fence-form.
