胞质颗粒:细菌细胞质中含有多种颗粒,大多为贮藏的营养物质,包括糖原、淀粉等多糖、脂类、磷酸盐等。胞质颗粒又称为内含物(inclusion),不是细菌的恒定结构,不同菌有不同的胞质颗粒,同一菌在不同环境或生长期亦可不同。
鉴别要点是特殊分泌颗粒、细胞膜特化结构及胞质内细胞器和细胞其他结构。
Changes of the fine structures of tumor cells including special intracellular secretory granules, cell membrane and certain cell organelles.
碱性磷酸酶染色:细胞诱导培养第3代后可见胞质内有大量灰黑色颗粒或块状沉淀,呈现碱性磷酸酶染色阳性。
Alkaline phosphatase staining: After the 3rd generation culture, there was a large amount of gray-black granule or block deposit, which showed positive alkaline phosphatase staining.
胞质内含有大量线粒体、食物泡和多糖颗粒。
