摘要
本实验通过对小鼠腹腔注射地塞米松的方法,较简便地对胸腺组织内的胸腺哺育细胞进行了观察,并用间接免疫荧光法成功地标记了胸淋哺育细胞内的精氨酸加压素和催产素,提示胸腺哺育细胞是胸腺内含有某些肽类激素的淋巴—上皮细胞复合体,它的存在为 T 细胞在胸腺内的分化发育提供了独立的微环境。
The thymic nurse cell was observed with great ease by means of dexamethasone injection to the mice intraperitoneally,and the arginine vasopressin and oxytocin were labelled successfully using indirect immunoflurescense.The results indicate that TNC is a kind of lympho-epithelial cell containinig some kinds of peptide hormons.The exsistance of TNC provides an isolated microenvironment for the differentiation and development of thymic T lympnocytes.
