Concentration–response curves for cisplatin, DM-EVs, PD-EVs, and the combination of DM-EVs and PD-EVs against breast and skin tumor cells. (ad) Cytotoxicity of cisplatin (a), DM-EVs (b), PD-EVs (c), and DM-EVs + PD-EVs (d) against human breast cells. (eh) Cytotoxicity of cisplatin (e), DM-EVs (f), PD-EVs (g), and DM-EVs + PD-EVs (h) against human skin cells. (i) half-maximal inhibitory concentration (IC50) values of cisplatin, DM-EVs, PD-EVs, and the combination of DM-EVs and PD-EVs for breast and skin cells. Cisplatin was used as a positive control.
