Clara氏在1937年对1881年Klliker氏提出的终术细支气管细胞进行了详细的报告。经过半个世纪的今天,这种细支气管无纤毛上皮细胞(Clara细胞)引人关注的许多疑点开始被认识。本文就认识Clara细胞的4个要点加以论述。[Clara细胞的形态] Clara用当时的光学显微镜从人和家兔的细支气管到肺泡的详细观察,在细支气管观察到许多顶浆分泌的无纤毛上皮细胞,其后称为Clara细胞。它向细支气管内呈园顶状突出,在细胞质内有许多线粒体,细胞质具有丰富的光滑及粗糙面内质网,在管腔自由缘有电子密度高约0.5μm的Clara颗
Clara’s detailed report of the final bronchiole cell line proposed by Klliker in 1881 in 1937. After half a century today, many doubts that this bronchioal non-ciliated epithelial cell (Clara cell) attracts attention are beginning to be recognized. This article discusses Clara cell four points to be discussed. [Clara Cell Morphology] Clara observed the detailed observation of bronchoalveolar lavage from human and rabbit to the alveoli using the then light microscope, and observed many of the apical secretion-free ciliated epithelial cells in the bronchioles, which were later referred to as Clara cells. It is prominent to the bronchioles dome-shaped, there are many mitochondria in the cytoplasm, the cytoplasm is rich in smooth and rough endoplasmic reticulum, free electron density in the lumen with electron density of about 0.5μm Clara
