Fabrication of biocomposites composed of natural rubber latex and bone tissue derived from MC3T3-E1 mouse preosteoblastic cells

Abstract

Natural rubber latex (NRL) is mainly used around traditional industrial products, but currently their target application is continuously expanding into tissue engineering. To broaden our knowledge of application in tissue engineering of NRL, we have focused on the surface modification of NRL nanoparticles through the biomineralization of hydroxyapatite (HA) using simulated body fluid in order to create a better cytocompatibility with controlled cell adhesion and mineralization properties in osteogenic culture to determine the effect on bone outcomes. Using MC3T3-E1 mouse osteoblastic-like cells incubated with NRL nanoparticles coated with HA layer, we have examined the osteogenic differentiation and expressions of multiple proteins and characteristic genes of mature osteoblast. We have successfully prepared the biocomposites composed of NRL and bone tissue.
