Verbascoside prevents the high glucose-inhibited cell proliferation and wound healing capacity of gingival epithelial cells. (A) PrestoBlue and (B) MTT assays were carried out to examine the cell viability of high glucose-treated cells in response to various concentrations of verbascoside (25, 50 and 100 μM) or N-acetyl-l-cysteine (NAC; 5 mM); (C) LDH assay was conducted to show that verbascoside protected cells against high glucose-induced cytotoxicity. Triton X-100 served as a positive control group; (D) wound healing capacity was tested using a two-well culture-insert. * indicates p  <  0.05 compared to the control group (CON); # indicates p  <  0.05 compared to the high glucose group (HG).
