Saliva stimulates fibroblast migration in a wound healing scratch assay. (a) Representative photographs of Day 0 (top) and Day 2 (bottom) showing intrinsic scratch wound closure of skin fibroblasts (left) and gingiva fibroblasts (right). Dotted line represents initial scratch border on Day 0. (b) Quantification of scratch area closure (ingrowth area) after exposure to saliva. Data represents mean ± SEM of three independent experiments, each with an intra‐experiment duplicate; ^* p < .05; ^** p < .01; ^*** p < .001; Friedman test followed by Dunn's multiple comparisons test [Colour figure can be viewed at wileyonlinelibrary.com]
