In vitro study of rASCs. (A) Cytotoxicity result. The cytotoxicity of RGO-CPCs was lower than No RGO at 24 hours, whereas the cytotoxicity of all CPCs was insignificant at 12 hours (n = 5). (B) Cell adhesion result. There is no significant difference except for 1% RGO (n = 5, LSD). (C) Cell viability result. On day 7, the cell viability of 0.1 and 1% RGO significantly decreased compared with No RGO (n = 5, LSD). (D) ICC result. Vinculin expression decreased with increased 1% RGO. Scale bars = 100 μm. ICC: immunocytochemistry.
