胆小管

胆小管在胚胎早期已经形成，胆管由肝母细胞演化而来；

In an early embryo , a bile canaliculus has been found . A bile duct is evolved from original hepatic cell .

胆小管发育至胚胎晚期，封闭其管腔的紧密连接发育完善。

When the bile canaliculus developed to the last stage of the fetus , the tight junction closing the lumen developed into a perfect condition .

In normal human tissues , low to high expressions of BCRP in placental syncytiotrophoblasts , in the epithelium of the small intestine and colon , in the liver canalicular membrane , in ducts of the breast , in endothelium of the blood vessel and in stem cells were reported .

胆汁通道起始于由肝细胞组成的胆小管。

Biliary passages begin as tiny bile canaliculi formed by hepatocytes .
