用光学显微镜、透射和扫描电子显微镜对12.75~16天胎儿胸腹膜管的发育和闭合进行了研究。本文所描述的主要时间事件是：(1)肺芽的尾端伸向胸膜腹膜管(12.75~13.50天)；(2)尾端在14天时位于管区的内侧；(3)两根管都变得月牙形，直径均匀，直至闭合。同时，发育中的横隔膜和相关的胸膜腹膜皱褶呈现出更多的尾部位置。这两个管区都与肝、肺、性腺脊和肾上腺交界。此外，在左侧，胃和中胃也与早期管交界。右侧先于左侧闭合(右侧为14.75~15天，左侧为15~15.25天)。
Pleuroperitoneal canal development and closure were studied with light microscopy and transmission and scanning electron microscopy in 12.75‐ to 16‐day fetuses. The major chronological events described in this paper are (1) the caudal tips of the lung buds projecting to the pleuroperitoneal canal (12.75 through 13.50 days); (2) the caudal tips of the lungs becoming situated medial to the canal areas at 14 days; and (3) both canals becoming crescent shaped with a uniform diameter until closure. Concurrently, the developing diaphragm and associated pleuroperitoneal folds assume more caudal positions. Both canal regions are bordered by the liver, lung, gonadal ridge, and suprarenal glands. In addition, on the left side, the stomach and mesogastrium also border the early canal. The right canal closes before the left (right, 14.75–15 days; left, 15–15.25 days).
