Abstract
To know about whether a bone substitute material octacalcium phosphate (OCP) is associated with bone formation by acting on surrounding tissue-derived cells, such as muscle cells, the effect of OCP was investigated on muscle-derived myoblast C2C12 cells in vitro. C2C12 cells were cultured with or without OCP granules. The diameter of the myotube formed from C2C12 cells with OCP was larger than that without OCP. mRNA expressions of myoblast differentiation markers (MyHC, MCK) and myokine (FGF-2) were increased by OCP, while Fndc5 and osteoglycin (myokine) were decreased. The alkaline phosphatase activity of mesenchymal stem cells was increased by adding the extract of media cultured with C2C12 cells and OCP up to 14 days. The chemical and spectroscopic analyses indicated that OCP hydrolysis progressed towards Ca-deficient hydroxyapatite in the media. The results suggest that OCP promotes myoblast differentiation and assists osteoblast differentiation through the myokines secretion under the environment induced by OCP hydrolysis.
期刊介绍:
Dental Materials Journal is a peer review journal published by the Japanese Society for Dental Materials and Devises aiming to introduce the progress of the basic and applied sciences in dental materials and biomaterials. The dental materials-related clinical science and instrumental technologies are also within the scope of this journal. The materials dealt include synthetic polymers, ceramics, metals and tissue-derived biomaterials. Forefront dental materials and biomaterials used in developing filed, such as tissue engineering, bioengineering and artificial intelligence, are positively considered for the review as well. Recent acceptance rate of the submitted manuscript in the journal is around 30%.
