在呼吸系统疾病中,Ⅱ型肺泡上皮细胞及其特征性结构板层小体(或板层体)受到人们的广泛重视。1966年Weibel首先在肺泡腔中发现管状的髓鞘结构,1973年Gil观察了分离的管状髓鞘结构,1977年Paul则在试管中把板层小体转变成管状髓鞘结构。近二十年来,许多学者通过电 In respiratory diseases, type II alveolar epithelial cells and its characteristic structural lamellar body (or lamellar body) by people’s attention. In 1966 Weibel first found a tubular myelin structure in the alveolar space. In 1973, Gil observed the isolated tubular myelin structure. In 1977, Paul transformed the lamellar body into a tubular myelin sheath in a test tube. In the past two decades, many scholars have adopted electricity
