Fig. 6From: Engineering a HEK-293T exosome-based delivery platform for efficient tumor-targeting chemotherapy/internal irradiation combination therapyAntitumor efficacy in vivo. A Growth curves of the 8505C tumors after the mice were injected with PBS, iRGD-Exos, Na131I, blank-Exos-131I, iRGD-Exos-131I or Dox@iRGD-Exos-131I. Tumor volume was measured every 3 days until the end of the observation period. B Ex vivo image of the tumors from the sacrificed mice at 18 days postinjection. C Quantitative analysis of the tumor weights from the mice in the different treatment groups. D Changes in body weights of the different drug-treated mice during the observation period. Data are presented as the mean ± SD. *P < 0.05, ***P < 0.001Back to article page
