非淋巴细胞参与二级淋巴器官的免疫学反应。它们存在于脾脏白髓和淋巴结的不同部位,主要与T细胞和B细胞的微环境有关。根据形态学、酶和功能特征可把非淋巴细胞分为树突状网状细胞(DRC)、嵌合细胞(IDC)和金属性细胞。作者用鼠龄2.5月的Wistar大鼠8只研究了正常情况下大鼠胸腺中金属性细胞的分布和形态学特征。方法是:将胸腺用Bouin Non-lymphoid cells are involved in the immunological response of secondary lymphoid organs. They exist in different parts of the spleen, white pulp and lymph nodes, mainly related to the microenvironment of T cells and B cells. Non-lymphoid cells can be divided into dendritic reticular cells (DRCs), chimeric cells (IDCs) and metallic cells according to morphological, enzymatic and functional characteristics. The authors studied the distribution and morphological features of metallic cells in the thymus of rats under normal conditions using 8 Wistar rats of 2.5 years old. The method is: the thymus with Bouin
