Objective:To investigate that the effect of adipose-derived stem cells(ADSCs)on immune function of C57 mice with thymomas induced by irradiation,and plausible mechanism.Methods:A total of 32 cleaning degree C57BL/6mice were divided into four groups:control group of 8mice with non-irradiation;irradiation group of 8mice with irradiation;irradiation+ADSCs group of 8mice,thymoma model mice were injected 0.5mL ADSCs via tail vein at one day after last irradiation;non-irradiation+ADSCs group of 8 mice with the sa...
