Fig. 1From: Egr-1 mediates low-dose arecoline induced human oral mucosa fibroblast proliferation via transactivation of Wnt5a expressionLow dose Arecoline induces the proliferation of fibroblasts. Human oral fibroblasts were treated with different dose Arecoline for indicated times, then cell proliferation rate was quantified. * denotes p < 0.05Back to article page
