Fig. 1From: TRPC expression in human periodontal ligament cells and the periodontal tissue of periodontitis mice: a preliminary studyExpression of osteoblast differentiation factors during osteoblast differentiation of human PDL cells. A Representative images of ALP staining and ARS staining during the differentiation period. B mRNA expression of osteoblast differentiation factors, Runx2 and OCN during the differentiation period. Data are presented as the mean ± SE. *p < 0.05 versus control, **p < 0.01 versus control, ***p < 0.001 versus control.
