Gene expressions of fibroblasts cultured on different surfaces after incubation for 3, and 7 days: (a) TGF-β1, (b) CTGF, (c) α-SMA, (d) Col-I; (e) collagen secretion of L929 determined with Sirius Red staining incubated on different coatings for 3 and 7 days; (f) staining pictures of collagen secretion at 7 days of incubation. Data are presented as the mean ± SD, n = 4, (**)p < 0.01 compared with the Ti, and (##)p < 0.01 compared with HA.
