In vivo anti-tumor effect of DNMF/PLGA NPs. A The relative tumor growth curves from 0 to 14 days. B The ex vivo tumor weights after different treatments at 14 days. C Body weight of 4T1 tumor-bearing mice in different groups. D Images of ex vivo 4T1 tumors after receiving different treatments at 14 days. E Images of in vivo 4T1 tumors after receiving different treatments at different time points. F H&E, TUNEL, VEGF, and Ki-67 antibody staining images of tumor tissues in different treatment groups. n = 5, mean ± SD. Two-way ANOVA with repeated measures with Tukey’s post-hoc test. *p < 0.05
