The ability of kojic acid treatment on cancer cell growth by scratch healing assay (HepG2) was plated for 24 h and then a scratch was carried out as described in methods section. Then cells treated with 0 and 50 μg/ml of crystalized and standard kojic acid for 24 h, the width of the scratch was determined at 0 and 24 h. of incubation. Representative images of wound closure of different treatments (a). Calculations of wound closure width after 0 and 24 h of different treatments (b). All data are means (n = 3) of independent experiments ± SD at p < 0.05
