Expression of angiotensin ⅱ receptors in mouse ureteric bud cell s

血管紧张素Ⅱ受体1和受体2在小鼠 肾脏 输尿管 芽中的表达

Objective To investigate the growth pattern of ureteric bud ( UB ) and nephron number induced by UB in developing mouse kidney .

目的观察小鼠肾发育过程中 输尿管 芽（UB）生长方式及其与诱导产生的肾单位数目之间的变化规律。

Conclusion The expression of AT_ ( 1 ) R appears to correlate with the branching of ureteric bud cell and the differentiation and proliferation of glomerular and tubular cells .

结论AT1R与 输尿管 芽分支不断延长以及肾小球和肾小管的增殖和分化密切相关。

The number of branching ureteric bud could control nephron developmental decisions .

输尿管 芽分支 多寡是决定肾小球和肾小管数量的关键。

Results : At 18th day of incubation ureteric bud from cloaca grew into metanephrogenic tissue which produced many metanephrogenic vesicles .

结果：孵育第18天，从泄殖腔附近发出的 输尿管 芽向生后肾组织侵入生长，生后肾组织产生许多生后肾小泡。
