THE SENSITIVITY OF EHRLICH ASCITIC CARCINOMA CELLS TO THE EMPERIPOLESIS OF THYMUS LYMPHOCYTES

In mixed lymphocyte-tumor all culture in vitro, the ability of thymus lymphocytes adhering to tumor cells was found to be essentially consistent with its emperipolesis index, though not synchronous. Tumor cells at different progressive stages and in the mixed cultures with or without Con A stimulation also varied in the sensitivity to lymphocyte adhesion and emperipolesis. Tumor adhesiveness anl emperipolesis of theymus lymphocytes and their PNA-, PNA subgroups were shown to be different significantly from splenic lymphocytes. Thymosin exhibited certain promotive effect on lymphocyte-tumor adhesion and emperipolesis.
