在光学显微镜下对胰岛细胞的鉴定,主要依靠对这些细胞分泌颗粒的区别染色。自从Lane于1907年在豚鼠胰岛中描述了含有不同类型颗粒的A和B两种细胞以来,已有各种染色方法应用于胰岛细胞的区别染色。1931年,Blodm首先采用Mallory-Heidenhainazan染色法来染人的胰腺标本,在同一标本中能区别A、B和D细胞,这是胰岛细胞三 The identification of islet cells under an optical microscope mainly depends on the distinction of the secretory granules of these cells. Since Lane described two types of cells, A and B, containing different types of particles in guinea pig islets in 1907, various staining methods have been applied to differentiate staining of islet cells. In 1931, Blodm first used the Mallory-Heidenhainazan staining method to stain human pancreatic specimens, in the same specimen can distinguish A, B and D cells, which is islet cell III
