Bio-Oss® modified by calcitonin gene-related peptide promotes osteogenesis in vitro.

ABSTRACT: Bio-Oss® and α-calcitonin gene-related peptide (CGRP) are involved in osteogenesis. However, it has remained to be assessed how α-CGRP affects the effect of Bio-Oss. In the present study, primary osteoblasts were incubated with α-CGRP, Bio-Oss, α-GGRP-Bio-Oss or mimic-α-CGRP. The proliferation rate, mineralization nodules, alkaline phosphatase (ALP) activity and the expression of osteogenic genes were measured by a Cell Counting Kit-8 assay, Alizarin Red-S staining, ALP activity detection and reverse-transcription quantitative PCR as well as western blot analysis, respectively. The proliferation rate, ALP activity and the number of mineralization nodules were significantly increased in the α-CGRP-modified Bio-Oss group compared to that in the Bio-Oss group. The mRNA and protein levels of o
