蒙古绵羊胚胎肠绒毛的组织发生

Histogenesis of Intestinal Tomentum of the Mongolia Sheep′s Embryo

用组织学常规方法研究32-550 mm蒙古绵羊胚胎各段肠的组织学结构。研究结果显示,蒙古绵羊各肠段在发育过程中都有绒毛的发生,且绒毛发育呈现了各自不同的特点：肠绒毛发生时期不同,发生过程不同,大肠绒毛退化消失时期也不同。

Using the normal method of histology,the histogenesis of embryonic intestines of 32-550 mm about the Mongolia sheep is investigated. The result shows that the histogenesis of intestinal tomentum in all stems exists during the process of development and the histogenesis of intestines presents diverse characteristics. The histogenetic time, generated course and the degenerated time of intestinal tomentum are quite difference from each other.
