LPLI enhanced the expression of osteogenic marker genes. The mRNA expression of BMP2 (a), OC (b), RUNX2 (c) and ALP (d) was analyzed by the method and normalized to the OIM-0 group. The data are shown as the mean±s.d. (n=4), and the levels of statistical significance are indicated as follows: *P<0.05 and **P<0.01 relative to the OIM-0 group. ALP, alkaline phosphatase; LPLI, low-power laser irradiation; OIM, osteo-induction medium.
