Abstract:
To study immunophenotype and cytotoxicity of the immunocytes in bone marrow and peripheral blood after activation by combined cytokines, mononuclear cells (MNC) of bone marrow and peripheral blood were activated by IFN-gamma, IL-1, IL-2 and McAb-CD3 in vitro. The cell amount and morphology during culture were observed. Cytochemical staining and immunophenotype analysis were done before and after culture in two groups of MNC. Cytotoxicity was tested by MTT method. The results showed that the cell number of two groups increased obviously in culture (P < 0.05), while the peripheral blood mononuclear cells increased more markedly (P < 0.05). The cytochemical staining showed POX decrease, but PAS increase in two groups. The positive ratios of CD3(+), CD56(+) and CD38(+) cells in two groups increased obviously after culture (P < 0.05), but there was no significant difference between those two groups. CD3(+) CD56(+) cells increased obviously in peripheral blood mononuclear cells activated by cytokines (P < 0.05), but CD3(+) CD56(+) cells did not increase in bone marrow mononuclear cells. There was no significant difference between two groups' cytotoxicity. It was concluded that IFN-gamma, IL-1, IL-2 and McAb-C D3 increased cell number and cytotoxicity of both bone marrow and peripheral blood mononuclear cells that can be used in cell immunotherapy.
