Abstract

The aim of this study is to improve the mechanical property of calcium phosphate cement (CPC) via adding of the biocompatible and adhesive dopamine (DA-CPC). The effects of DA on properties of DA-CPC were investigated by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), compressive testing and scanning electron microscopy (SEM). The morphology, proliferation and differentiation of MC3ET3-E1 osteoblast co-cultured with DA-CPC were evaluated by fluorescence microscopy, Alamar Blue assay and alkaline phosphatase assay, respectively. It is found that the conversion of α-TCP and DCPD in DA-CPC is promoted due to the self-polymerization of DA and the phases of DA-CPC are similar to those of the control CPC. Meanwhile, the compressive strengths of DA-CPC are improved significantly with the addition of DA. The presence of DA in DA-CPC could promote the adhesion and the proliferation of osteoblasts in the initial stage, while it does not affect the differentiation of the osteoblasts. The present DA-CPC has good biocompatibility to be used in clinic potentially. The present study provides a new approach to improve the mechanical strength of CPC.
