a, b,
In vitro cytotoxicity of primary hepatocytes cultured in liver matrix coated plates. The hepatocytes were treated with free CPZ and CPZ-loaded NPs (NP) (a) or free Wtmn and Wtmn-loaded NPs (b) without (hollow columns) or with (solid columns) macrophage incubation. The cytotoxicity was analyzed by MTS assay 6 h and 24 h after treatments. Data represent mean ± SEM. (n = 6). Statistical significance was assessed using the Mann Whitney test. *p < 0.05, **p < 0.01. c, d,
In vivo hepatotoxicity in CD-1 mice treated with free CPZ and CPZ-loaded NPs (c) or free Wtmn and Wtmn-loaded NPs (d). The mice were either without (solid columns) or with (stripe columns) macrophage depletion. The hepatotoxicity was analyzed by ALT and AST 24 h and 36 h after treatment with free CPZ and CPZ-loaded NPs, or 6 h and 12 h after treatment with free Wtmn and Wtmn-loaded NPs. Data represent mean ± SEM. (n = 8-10). Statistical significance was assessed using the Mann Whitney test. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001.
