A Comparative analysis of the bioaccessibility of curcumin, CAA, and CD EXO + CAA. The statistical analysis was carried out by a one-way ANOVA test with n=3. (*P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001). Bars indicate mean ± SEM. B DiO-labelled exosomes interact with HNC cells. C The cell viability of KB-3-1 cells and HEp-2 cells treated with CAA and CD EXO + CAA was detected by MTT assay for 48 h. Graphs represent the mean ±SEM for the cell viability experiment
