[Characteristics of cells participating in the adoptive transfer of tumor-associated suppressor activity].

The application of a complex of methods for fractionation of mouse spleen cells with transplanted rhabdomyosarcomas has shown that optimal conditions for adoptive intravenous transfer of the tumour-associated suppressor activity are created under joint injection of the primed macrophages and lymphoid cells of spleen (from animals with the progressively growing tumours) interacting with the macrophages to syngenic recipients.
