* I型肺泡细胞(type I alveolar cell):又称扁平肺泡细胞,细胞扁平,含核部分略厚,其余部分很薄,在光镜下较难辨清。核扁平较小,核周胞质有少量线粒体、高尔基复合体和线粒体,周边部的胞质内细胞器很少,近胞膜处有许多的吞饮小泡。数量占肺泡细胞总量的25%,但是覆盖97%的肺泡表面,是肺与血液 ...
Abstract: The alveolar epithelium comprises two main cell types: the alveolar type I and alveolar type II cell. The type I cell is a complex branched cell with multiple cytoplasmic plates that are greatly attenuated and relatively devoid of organelles; these plates represent the gas exchange ...
Description Type I alveolar epithelial cells extend across several air sacs and cover more than 95% of the alveolar surface area. They are specialized to serve as very thin (often only 25 nm in width) gas-permeable components of the blood-air barrier. The Type I Alveolar cells are the targ...

In injured alveolar epithelium, a diminished type I cell and a focal type II cell immunoreactivity was found. Electron microscopy of immunogold-labelled lung tissue confirmed the type I cell specificity of MEP-1. In severely injured pulmonary parenchyma MEP-1-negative areas occurred, which were ...
ALVEOLAR TYPE II CELL (TII) SYNTHESIS OF SATURATED PHOSPHATIDYLCHOLINE (SPC) IS DELAYED BY ENDOGENOUS AND EXOGENOUS ANDROGENS IN THE FETAL RATIncorporation ofH-choline intoH-SPC by slices of whole fetal rat lung is lower in males than in females at 20 days gestation (day 0= mating) (Torday...
Type I alveolar epithelial cells These cells have few cytoplasmic organelles but are remarkable for their attenuated cytoplasm, which extends long distances from the nuclear zone of the cell (seeFigs 1.27 and 1.28) and may even penetrate the alveolar wall so that one cell contributes to the linin...
Two epithelial cell types cover the alveolar surface of the lung. Type II alveolar epithelial cells produce surfactant and, during development or following wounding, give rise to type I cells that are involved in gas exchange and alveolar fluid homeostasis. In culture, freshly isolated alveolar type...
