In vitro cytotoxicity of different formulations.
(A) Cytotoxic effect of void CS-CD147-NPs on HepG2 and SMMC-7721 cells after incubation for 24 h (n = 3); (B) cytotoxic effect of α-Hed, α-Hed-CS-NPs and α-Hed-CS-CD147-NPs on HepG2 cell line after incubation for 24 h (n = 3); (C) cytotoxic effect of α-Hed, α-Hed-CS-NPs and α-Hed-CS-CD147-NPs on SMMC-7721 cell line after treatment for 24 h (n = 3); and (D) cytotoxic effect of various formulations containing α-Hed on HSC cell line after incubation for 24 h (n = 3). *p < 0.05, **p < 0.01 versus α-Hed-CS-NPs.
