Abstract:
Two hour after LAK—like cells were co—cultured with gastric cancer cells,the mixed sus-pension was spread on slids and dyed with histochemical method.Through analysing the dyedcells,we directly confirmed what subset the LAK—like cells belonged to.The featrue of LAK—like cells adhering to cancer cell was observed under electron micrscope in our experiment.A-mong the lymphoctes which were adherent to cancer cells,the number of CD8~+ cells was in-creased.Most of adherent to cancer cells,the number of CD8~+ cells was increased.Most of ad-herent cells were TAC~+,suggesting that the expression of TAC antigen plays an important rolein cell mediated cytotoxity.
