Article Title: Enhanced anti-angiogenic effects of aprepitant-loaded nanoparticles in human umbilical vein endothelial cells
doi: 10.1038/s41598-024-70791-y
Figure Lengend Snippet: Uptake of nanoparticles labeled with coumarin into HUVEC cells depending on time ( A ) and fluorescence intensity-time graph of nanoparticles labeled with coumarin into HUVEC cells ( B ). For cellular uptake experiments, a two-way ANOVA was used to test the change of fluorescence intensity versus time (0.5, 2, 24 h). The data are presented as mean ± SD (n = 3), normalized to cell numbers. A Bonferroni post-hoc test was used to calculate significant differences between groups (**p < 0.01, ***p < 0.001, ****p < 0.0001).
