小鼠胸腺基质细胞的类型和分布

THE TYPES AND DISTRIBUTION OF STROMAL CELLS WITHIN THE MOUSE THYMUS

本文用特殊染色方法和酸性复红法对小鼠胸腺内各种基质细胞进行了鉴别,从染色特性及细胞形态,可区分出各型上皮网状细胞、保姆细胞、巨噬细胞、肥大细胞的?光镜下观察了小鼠胸腺内各种基质细胞的分布,并证实小鼠胸腺髓质内含有胸腺小体。本文就电镜所见髓质两种上皮细胞类型并结合PAS反应,对髓质内亮细胞的特性进行了讨论。

Using special staining and acid fuchsin method the various types of stromal cells of themouse thymus were idenfified in the present study. According to cell morphology and stainingpropertics, the various types of epithelial reticular cells, nurse cells, macrophages, mast cells anddendritic cells could be distinguished. The distribution of the various types of stromal cells withinthymus were examined by light microscopy and the Hassall's corpuscles were seen in the murinethymic medulla. Two types of the epithelial reticular cells in the medulla were observed by electronmicroscope and the nature of the light cells in the mudulla was discussed in combinationwith PAS reaction
