Figure 7. Wound healing rate of cell scratch assay in different treatment groups observed under a 40× microscope. Among them, the wound healing rate of the cell scratch was the fastest in the Control group and NC group, followed by the cassia polysaccharide group, which showed no significant difference from the Control group and NC group in terms of cell migration rate; while the cell migration rate was the slowest in the PAX6-shRNA group (n=3).
