Fig. 1. Expression of FN, ON, TIMP1, ILK, Integrin a2, Integrin a5, Integrin av, Integrin b1, Integrin b3, Talin-2, Paxillin, Syndecan-4, p130CAS, c-Src, c-Crk, c-Jun, RAC1 gene of human gingival fibroblasts cultured on smooth (NE0), acid-etched (E0), microgrooved (E60/10), and fibronectin-immobilized (NE0FN, E0FN, and E60/10FN) titanium substrata after 48 and 72 h of culture using semi quantitative real-time RT-PCR. The relative expression levels were analyzed by normalizing with GAPDH, and are presented as fold changes relative to the control, NE0 at 48 h of culture. One-way ANOVA (n = 5). ***: significant difference (P < 0.001). **: significant difference (P < 0.01). *: significant difference (P < 0.05). Note that only significant differences between the highest gene expression levels and other gene expression levels are presented.
