Fig. 2From: Local radiotherapy for murine breast cancer increases risk of metastasis by promoting the recruitment of M-MDSCs in lungRadiotherapy changed MDSCs subsets distribution in lung of BALB/c mice bearing 4T1 tumor. a and b Local radiotherapy changed macrophages and MDSCs infiltration of lung in 4T1 tumor-bearing BALB/c mice. The representative flow cytometry data was shown. c, d, e and f Local X-ray irradiation induced significantly expansion of M-MDSCs, and reduction of PMN-MDSCs, respectively. g and h Local X-ray irradiation decreased macrophages infiltration. i The infiltration number of M-MDSCs in lung tissues was positively correlated with the number of pulmonary nodulesBack to article page
