Abstract

In the article entitled “Low-Level Laser Therapy Stimulates Mineralization Via Increased Runx2 Expression and ERK Phosphorylation in Osteoblasts,” published in an online supplement to Photomedicine and Laser Surgery [Photomed. Laser Surg. 2010; 28(Supplement 1), S167–S172], errors were mistakenly introduced to Figures 2, 3, and 4 before publication. Figures 2, 3, and 4 appear below as they should have appeared in the article on the journal website. The publisher regrets the error.

FIG. 2.

Effect of LLLT on IGF-I protein expression after the cells were exposed to LLLT (1.91 J/cm²). Protein expression of IGF-I was determined by using Western blotting at 12–48 h.

FIG. 3.

Effect of IGF-I receptor inhibitor (PPP) on the LLLT-induced IGF-I protein (a) and mRNA (b) expression. Cells cultured with or without PPP (100 ng/ml) were subject to LLLT (1.91 J/cm²), and the expression of IGF-I was determined after 48 h by using Western blotting and real-time PCR. Each bar indicates the mean ± SD of three separate experiments. *p < 0.05, LLLT vs. controls, ^† p < 0.05, LLLT vs. LLLT + PPP.

FIG. 4.

Effect of IGF-I receptor inhibitor (PPP) on the LLLT-induced Runx2 protein (a) and mRNA (b) expression. Cells cultured with or without PPP (100 ng/ml) were subject to LLLT (1.91 J/cm²), and the expression of Runx2 was determined after 48 h by using Western blotting and real-time PCR. Each bar indicates the mean ± SD of three separate experiments. *p < 0.05, LLLT vs. controls, ^† p < 0.05, LLLT vs. LLLT + PPP.
