Fig. 1From: Curcumin upregulates transforming growth factor-β1, its receptors, and vascular endothelial growth factor expressions in an in vitro human gingival fibroblast wound healing modelCytotoxicity of curcumin in human gingival fibroblasts. Cells were seeded at 5 × 103 cells per well in 96-well plates and treated with varying concentrations of curcumin or DMSO for 24 h. Cell viability was measured using the MTT assay. The data are presented as the mean ± standard deviation. *p < 0.05 compared to the control groupBack to article page
