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。
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
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。
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。
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。
