Fig. 4From: Tumor-specific delivery of KRAS siRNA with iRGD-exosomes efficiently inhibits tumor growthKRAS siRNA encapsulated in iRGD-exosomes inhibited tumor development in a xenograft mouse model. (a) Tumor-bearing nude mice imaging in vivo (n = 10 in each group). (b) Quantitative analysis of fluorescence intensity of tumors in mice after treatment. (c) Pathological section of tumor tissues from xenograft model mice (n = 10 in each group). ***, p < 0.001Back to article page
