Figure 6.

Wound healing of scratched oral fibroblast monolayer photographs and measurement of wound area were made immediately after the scratch (T0) and after 24 h (T24). (a) Representative images of wound-healing assay. (b) Wound repair was evaluated measuring the remaining cell-free area after 24 h and expressed as a percentage of the initial wound size (T0) assumed as 100%. ^∗∗p < 0.01; ^∗∗∗p < 0.001. IL-1β: IL-1β-primed cells; Van: Vanillin; Van (2 h)+IL-1β: Vanillin (2 h pretreatment) plus IL-1β.
