摘要: 正常小鼠表皮内有两种来源于骨髓和(或)脾脏的树突状表皮细胞、即Thy-1+树突状表皮细胞(Thy-1+dEC)和郎格罕细胞(LC).7.12-二甲基苯惠(7.12-Dimethyl benzan thracene,DMBA)是一种强化学致癌剂,每周一次涂抹于小鼠皮肤可诱发肿瘤.经抗小鼠Thy-1+和Ia抗原的单克隆抗体的间接免疫荧光和免疫荧光双标记法,我们证实(劝雄性小鼠表皮内Thy-1+dEC及LC密度分别低于雌性,(2)DMBA诱发肿瘤的机制可能与Thy-1+dEC和LC密度的动态变化有关.

Abstract: In murine skin there are two kinds of dendritie cells which, are derived from bone marrow and/or spleen, i.e. Thy-1 positive dendritic epidermal cells (Tliy-1+dEC) and Langerhans cells (LC). 7.12-Dimetyllbenzanthracene (DMBA) is a potent chemieal carcinogen which, when applied weekly to the mouse skin,causes the inductioa of skin tumors.
