ABSTRACT
Objective To evaluate the potential protective effects of erythropoietin (EPO) in combination with granulocyte-colony stimulating factor (G-CSF) on hypoxia cardiomyocytes. Methods After left ventricular cardiomyocytes were isolated from neonate rat, the cells were inoculated in a cultural atmosphere of 95%N2 and 5%CO2 for 24 h to establish hypoxia cardiomyocytes model. The protective effects of EPO and G-CSF at different concentrations were evaluated for the optimal concentration. Then the protective effects of EPO in combination with G-CSF were investigated under the optimized concentrations. The survival, apoptotic and necrotic rates of cardiomyocytes were assessed by flow cytometry. Results The mortality and ratio of apoptotic cells to total necrotic cell were higher in hypoxia cardiomyocytes than normal cells significantly (26.73% vs 5.63%,70.05% vs 37.83%, P0.05), and the combination group was much better than EPO and G-CSF alone groups (P
