Results of RT-PCR measurements showing expression by SaOS 2 osteoblast-like cells of some osteogenic marker (Collagen I = CollI, Alkaline Phosphatase = ALP, and Osteocalcin = OCN) at different time points on microrough (OXT) and machined (MAC) surfaces. Differences between values MAC vs OXT are significantly different with p < 0.05 for OCN at 48 and 96 h, and ALP at 96 h. Remaining data are not significantly different.
