Figure 5. qRT-PCR analysis of osteogenic differentiation related gene expression on the surface of the PPTi and NPTi after incubation with BMSCs for 14 days (n = 3).

Figure 5

(a) Relative ALP gene expression in BMSCs on different substrates after incubation for 14 days (n = 3). (b) Relative collagen I gene expression in BMSCs on different substrates after 14 days of culture (n = 3). (c) Relative osteopontin gene expression in BMSCs cultured on the PPTi and NPTi after incubation for 14 days. *p < 0.05, **p < 0.01 compared with NPTi. The results indicated that osteogenic differentiation-related gene expression in BMSCs was significantly greater on the PPTi at 14 days compared with the NPTi.
