Abstract:
Objective To identify the changes in proliferative activity and cytotoxicity of lymphokine activated killer(LAK) cells after in vitro co-culture with dendritic cells from umbilical cord blood(CBDC). Methods CBDCs were induced by using GM-CSF and IL-4,and then co-cultrued with allogenic LAK at different proportions.Proliferative activity and cytotoxicity of LAK cells were measured by MTT assay.Results The typical CBDCs were induced in vitro,and the cultured CBDCs stimulated the proliferation and cytotoxicity of LAK cells.The optimal proportion of CBDC and LAK was 1:10,at which the activated LAK showed the highest cytotoxic effect on the tumor cells.Conclusion The CBDCs can enhance the proliferation and cytotoxicity of LAK cells.
