目的研究小鼠肾脏肾小体发育中的细胞凋亡。
Objective to study the apoptosis in the development glomerulus of mouse kidney.
中肾包括肾小体、肾小管和填充于其间的拟淋巴组织，无皮质和髓质之分。
The kidney included renal corpuscle, renal tubules and lymphoid tissue, and it had no differentiation of cortex and medulla.
方法：应用组织培养、后肾移植和光、电镜技术对发育不同阶段的肾小体进行观察。
Results: The renal corpuscles developed in cultured and transplanted E13 d metanephroses, and there was no renal corpuscles before.
方法：光镜下应用体视学方法对生前和生后小鼠肾脏中各发育阶段的肾小体体积进行测量。
Methods : Renal corpuscles of different developmental stage at different age were investigated with stereological method at light microscopic level.
随胎龄增长，肾小体面数密度在下降。肾小体随机断面的平均直径和平均横截面积也略有下降。
The density and average diameter of the renal corpuscle decrease is bound to follow the increase in fetal month.
观察所见，5周胚肾已有肾小体发生，肾内的间充质首先分化成造血干细胞，在造血干细胞的诱导下形成毛细血管及肾小囊。
The result showed that the renal corpuscle had generated at the age of 5th week. First mesenchymal proper order the capillary of the glomerulus and the renal capsule were induced by the stem cells.
小尾寒羊胎肾中肾小体的发育模式为，肾皮质由深到浅可呈现数代处于不同发育阶段的肾小体，在肾皮质深层肾小体先发育成熟，表层不断形成新的肾小体使皮质增厚。
The renal corpuscle in deeper cortex matured first There were new renal corpuscles forming constantly in the shallow cortex, which made the cortex thicken; the fetal spleen was a hematopoietic organ.
