Figure 4: Effect of cucurmin (CUR) and cucurmin + insulin (I), 1 μg/ml on wound closure in hGF monolayer (Nikon Eclipse Ti E200 Fluorescence Microscope, 400X). (a) Post-48 hrs, the wound repair was observed morphologically using Nikon Eclipse Ti E200 fluorescence microscope and photographed. (b) Relative wound closure calculated using the formula ("X0 – Xyy)/(C0 – Cyy), where X0 is the scratch width at time 0; Xyy is the width after time yy exposure; C0 is the width of the scratch at time 0; Cyy scratch with after yy time exposure to the control.
