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 osteocalcin, Runt‑related transcription factor‑2 and ALP were significantly upregulated in the α‑CGRP‑Bio‑Oss group compared with those in the Bio‑Oss group. Furthermore, the effect of mimic‑α‑CGRP on osteogenesis was reduced as it carried a mutation. In conclusion, the present study was the first to demonstrate that Bio‑Oss modified with CGRP contributed to osteogenesis and may provide a novel formulation applied in the clinic for restoration of large bone defects.
