Cultivation of human blood monocytes on glass gives rise to cells nonspecifically cytotoxic to tumor cells. If the monocytes are cultured on collagen gels with no contact with glass, no such cytotoxic activity is induced. Killing appeared to be extracellular and probably contact dependent. The glass-induced cytotoxic activity was not related to protein content or cell viability. Rather, it appeared that the monocytes cultured on glass differentiated into cells resembling activated macrophages. On the other hand monocytes cultured on collagen differentiated into cells resembling resident tissue macrophages. These observations are compatible with numerous studies carried out in rodents, showing that activated macrophages, and not resident cells, are cytotoxic to tumor cells.
在玻璃上培养人血单核细胞会产生对肿瘤细胞具有非特异性细胞毒性的细胞。如果单核细胞在不与玻璃接触的胶原凝胶上培养,则不会诱导出这种细胞毒性活性。杀伤作用似乎是细胞外的,可能依赖于接触。玻璃诱导的细胞毒性活性与蛋白质含量或细胞活力无关。相反,在玻璃上培养的单核细胞似乎分化为类似于活化巨噬细胞的细胞。另一方面,在胶原上培养的单核细胞分化为类似于常驻组织巨噬细胞的细胞。这些观察结果与在啮齿动物中进行的大量研究一致,表明活化的巨噬细胞而非常驻细胞对肿瘤细胞具有细胞毒性。
