摘要
采用脾内免疫法，制备出两组大鼠抗小鼠胸腺基质细胞（Ｔｈｙｍｉｃｓｔｒｏｍａｌｃｅｌｌｓ，ＴＳＣ）的大－小鼠Ｂ细胞杂交瘤，已获４０个单抗分泌细胞株。小鼠胸腺切片免疫组织化学染色结果：（１）髓质ＴＳＣ反应阳性，皮质ＴＳＣ反应阴性；（２）皮、髓质ＴＳＣ反应均呈阳性且强度相似；（３）髓质ＴＳＣ反应强于皮质ＴＳＣ；（４）皮质ＴＳＣ反应强于髓质ＴＳＣ；（５）胸腺细胞的反应呈弥漫性。本实验结果不仅有利于鉴别ＴＳＣ亚群并且对研究Ｔ细胞发育有重要意义。
By means of intrasplenic
immunization,two series of rat anti-MTSC(mouse thymic stromal
cells)hybridoma have been established and 40 lines which secret MCAb
have been obtained.Supernatant from MCAb,screting cell lines have
been identified by immunohistochemical staining of mouse thymic
section(1) react only to medullary TSC,not to cortical TSC. (2)react
with cortical and me-dullarv TSC equally.(3) stronger reaction to
cortical TSC than to medullary TSC.(4) stronger reac- tion to
medullary TSC than to cortical TSC.(5) react to both TSC and
thymocytes Our result is not only useful to the identification of TSC
subset but also important to the investigation of T cell deve-lopment
