HSA–MWCNTs in vitro endocytosis mechanism in human liver cancer cells. A) Colocalization of Cy-Gp60 antibody and FITC–HSA–MWCNTs in HepG2 cells. B) Colocalization of Cy-Gp60 antibody and FITC–HSA–MWCNTs in hepatocyte epithelial cells. C) Colocalization of caveolin-1-Cy antibody and FITC–HSA–MWCNTs in HepG2 cells. Results are representative of three experiments. Scale bar: 20 μm in all panels. Abbreviations: DAPI, 4′-6-diamidino-2-phenylindole; FITC, fluorescein isothiocyanate; HSA, human serum albumin; MWCNTs, multiwalled carbon nanotubes.
