[Cytostatic effect of immune system cells on tumor cells].
The cytostatic effect of different lymphoid cells on tumour cells was studied in mice. It was shown that the cells differed in their ability to manifest cytostatic and natural cytotoxic activity. The interstrain variations of cytostatic activity levels in murine splenocytes were revealed. The degree of cytostatic action of effector cells on tumour cells depended both on effector-target cells ratio and on the incubation time of effector and target cells. The cytostatic effect of splenocytes and macrophages was demonstrated to be unrestricted by H-2 complex and independent of the tumour type. The data suggest that the cytostatic effector cells are heterogeneous and may be distinct from natural killer cells.
