Quantitative real-time PCR analysis of the levels of mRNA for osteogenesis-related genes in hPDLSCs cultured on the investigated surfaces at 14 and 21 days of culture. (a) mRNA levels of early transcription factor genes for osteogenic differentiation (Runx2, COLI, and ALP) at 14 days of culture. (b) mRNA levels of osteocalcin (OC), and osteopontin (OPN) at 14 days of culture. (c) mRNA levels of early transcription factor genes for osteogenic differentiation (Runx2, COLI, and ALP) at 21 days of culture. (d) mRNA levels of osteocalcin (OC), and osteopontin (OPN) at 21 days of culture. Values were normalized for GAPDH. data are the mean ± SD of three independent experiments. ∗p < 0:05 between the two challenged implants. Laser surface treated (Implant 1) acid etched implant (Implant 2).
