在离体混合细胞培养中,发现胸腺淋巴细胞能主动向艾氏腹水癌(EAC)细胞移动、相互粘附,並钻入瘤细胞内。其粘瘤和钻瘤指数的基本规律一致,但不同步,不同瘤龄期以及有无Con A刺激的瘤细胞对淋巴细胞的粘瘤和钻瘤作用的敏感性不同,胸腺淋巴细胞及其PNA~-和PNA~+亚群与脾脏淋巴细胞亦有显著差异。胸腺素对淋巴细胞的粘瘤和钻瘤作用有一定的促进作用。 In ex vivo mixed-cell cultures, thymus lymphocytes were found to actively migrate to and adhere to Ehrlich ascites carcinoma (EAC) cells and penetrate into the tumor cells. The basic rules of its myxoma and tumor index are the same, but not synchronous, different tumor stage and with or without Con A stimulation of tumor cells of lymphoma oncolytic tumor and tumor-sensitive role of different, thymus lymphocytes and their PNA ~ - and PNA ~ + subpopulation and spleen lymphocytes were also significantly different. Thymosin on the lymph node tumor and tumor-bearing role in promoting a certain extent.
