Abstract

The response of human osteoblasts to materials is crucial for evaluating biocompatibility of an implant material for bone defects. Previous work in our lab demonstrated that the response of human osteoblasts to orthopaedic and dental materials in vitro varies depending on the sex and age of the patient [1]. Osteoblasts from female patients older than 60 years old, adhered less and produced less matrix proteins and calcification than osteoblasts from younger female patients and all ages of male patients. Recently developed, porous tantalum demonstrates improved biomechanical properties for bone and good biocompatibility in in vivo human studies, however there are few, if any, in vitro biocompatibility studies on this material. In this project, we aimed to compare the phenotypic expression of human osteoblasts from young and old female patients to commercially available Ti-6Al-4V and porous tantalum in a well-developed in vitro system.
