摘　　要：本文用特殊染色方法鉴别出孕5个月人胎胸腺中各种基质细胞及其分布。从染色特性及细胞形态上,可区分出各型上皮网状细胞,保姆细胞,树突状细胞,巨噬细胞及肥大细胞。同时用抗角蛋白抗体在邻片上显示上皮网状细胞内的角蛋白。本文结果,为进一步研究胸腺功能提供了形态学基础。With special staining, the various types of stromal cells of the human fetal thymus at the fifthgestational month were shown in the present study. According to cell morphology and staining proper-ties, the various types of epithelial reticular cells, nurse cells, macrophages, mast cells and dendritecells could be distinguished. The distribution of the various types of stromal cells within thymus wasexamined by light microscopy. Simultaneously, using antikeratin antibody, the keratin in the epithelialreticular cells was shown at adjacent sections. The results in the present study provide a morphologi-cal basis for further investigation on the function of the thymus.
