Integrin α2 overexpression enhances cell osteogenic differentiation. (A) The relative mRNA levels of Runx2, Col1a1, and Ocn in scramble and integrin α2 overexpressed cell for 3 days. (B) Western blot analysis of Runx2, Col1a1, and Ocn proteins in scramble and integrin α2 overexpressed cell for 3 days. (C) Immunofluorescence staining showing integrin α2 dependent diverse expression of Runx2 (red, F-actin; blue, DAPI: green, Runx2). (D) The relative mRNA levels of Runx2, Col1a1, and Ocn in scramble and integrin α2 overexpressed cell cultured on S, SLA and SLM-AHT surfaces for 3 days. Statistical significance was determined by one-way ANOVA. Error bars represent SD (n = 3). *P < 0.05, **P < 0.01.
