This project aims to develop novel biocompatible surfaces using nanotechnology approaches to understand how cells attach to and grow on artificial bone materials. This research is significant because it combines novel nanofabrication and surface modification strategies for unprecedented control and manipulation of inflammatory cell behaviour relevant to orthopaedic implants. The project will overcome current limitations of uncontrollable inflammatory reactions to surfaces. The multifunctional surfaces are expected to give the biomaterials field new tools to control and maintain bone cell functionality, in vitro. Potential long-term benefits include applications as coatings in tissue engineering, regenerative medicine, and medical implants.Read moreRead less

Summary
Engineering microenvironments to regulate osteocyte 3D networks in vitro. Most knowledge of bone is based on only a fraction of cells found in bone because the majority of cells in our bones (called osteocyte cell networks) cannot easily be grown or studied outside the body. This results in the inability to understand how the bone organ functions. Using bioinspired engineering, this project will use advanced biomaterials to biofabricate, for the first time, osteocyte cell networks in vitro.

Most knowledge of bone is based on only a fraction of cells found in bone because the majority of cells in our bones (called osteocyte cell networks) cannot easily be grown or studied outside the body. This results in the inability to understand how the bone organ functions. Using bioinspired engineering, this project will use advanced biomaterials to biofabricate, for the first time, osteocyte cell networks in vitro. By unravelling how they are formed and controlled by manipulating their microenvironment, we will discover how different types of bones are formed. The benefits will be a valuable tool for the bone research community, allowing unresolved questions to be addressed in the future, such as how bone forms, repairs, and remodels.Read moreRead less
