Anti-inflammation and bone regeneration are the two major goals of periodontal therapy. We have demonstrated that chitosan (CS)/polyvinyl alcohol (PVA)/graphene oxide (GO)/astaxanthin (ASTA) nanofibers membranes prepared by electrospinning had favorable micro-morphology, good mechanical properties, and no cytotoxicity. In this study, CS/PVA/GO/ASTA nanofibers membranes were prepared to modulate both inflammatory response and osteogenic induction in vitro study. When the nanofibers membranes were co-cultured with RAW264.7 cells, glycoprotein nonmetastatic melanoma protein in the cells was highly expressed and RAW264.7 cells were polarized to M2 phenotype at the same time. In addition, following stimulation with nanofibers membranes, the messenger RNA (mRNA) and protein levels of Osteocalcin (OCN) and Runx2 in Bone marrow mesenchymal stem cells (BMSCs) were highly expressed. Taken together, these results suggested CS/PVA/GO/ASTA nanofibers membranes may promote the dissipation of inflammation and stimulate the differentiation of BMSCs into osteoblasts.
