a Representative micrographs pictures of HaCaT-HDF scratch assays immediately after the scratches, and in time course of the experiments. Scale bar, 100 μm. b Repair area percentage [as (Areat 0 − Area t/Areat 0) × 100] for the control and in presence of following stimuli: H-HA, L-HA H-HA/L-HA complex at 0.1 and H-HA/L-HA 1%w/v; the curves are averages of three different experiments with standard deviation within 5 % of the value
