DEVELOPMENT OF A NOVEL BIOMATERIAL FOR BONE TISSUE ENGINEERING. Tissue engineering of bone is emerging as a viable therapy for treating large defects in load-bearing bone. We wish to develop methods for combining novel heparan sulphate molecules (known to deliver growth factors to cell surfaces and thereby cause changes in bone cell phenotype) with load-bearing, macro-porous, biodegradable mineral/polymer biomaterials. Through the study of release profiles, protein adsorption and cell responses ....DEVELOPMENT OF A NOVEL BIOMATERIAL FOR BONE TISSUE ENGINEERING.

Through the study of release profiles, protein adsorption and cell responses to these derivatised biomaterials, a novel approach to bone replacement materials can be developed.Read moreRead less
Engineering Articular Cartilage with Zonal Structure and Function. This project addresses the National Research Priority of Promoting and Maintaining Good Health and specifically the Priority Goal of Ageing well, ageing productively. Osteoarthritis, the most common cartilage-related disease, affects nearly 1.4 million Australians, resulting in 2 in 1000 Australians undergoing total joint replacement, annually.

This project addresses the National Research Priority of Promoting and Maintaining Good Health and specifically the Priority Goal of Ageing well, ageing productively. Osteoarthritis, the most common cartilage-related disease, affects nearly 1.4 million Australians, resulting in 2 in 1000 Australians undergoing total joint replacement, annually. The incidence and impact of cartilage damage on the Australian health and economy is expected to increase with the ageing population. This work leads to the development of a novel cartilage engineering technology platform that addresses Frontier Technologies and will thus provide the foundation for translation of this technology to the international marketplace.

Tissue Engineering the Meniscus: Combining Novel Biomimetic Hybrid Scaffolds with Adult Stem Cells. Development of a meniscal implant ex vivo will provide significant health and economic benefits, given that worldwide, millions of people annually suffer from meniscus damage or loss. We believe that a tissue engineered meniscus, composed of a novel biomimetic scaffold which guides the differentiation of mesenchymal stem cells in a novel bioreactor will provide a solution to the problem of donor ....Tissue Engineering the Meniscus: Combining Novel Biomimetic Hybrid Scaffolds with Adult Stem Cells. Development of a meniscal implant ex vivo will provide significant health and economic benefits, given that worldwide, millions of people annually suffer from meniscus damage or loss. We believe that a tissue engineered meniscus, composed of a novel biomimetic scaffold which guides the differentiation of mesenchymal stem cells in a novel bioreactor will provide a solution to the problem of donor scarcity in meniscal repair. Success in this project will lead directly to large-animal studies and clinical trials. The training of four early careeer researchers involved in this project will also be of significant benefit to the Australian Tissue Engineering and Biomaterials community.Read moreRead less
NOVEL TRI-BLOCK CO-POLYMERS FOR CONTROLED RELEASE OF PROTEINS FOR OSTEOGENESIS. This research is being driven by the need for a scaffold for orthopaedic reconstruction that provides controlled release of growth factors to enable rapid healing. None of the current systems possess the required combination of properties to enable new tissue to regenerate rapidly. The aim of this project is to design a system for sustained drug release using block copolymer micelles to encapsulate growth factors and ....NOVEL TRI-BLOCK CO-POLYMERS FOR CONTROLED RELEASE OF PROTEINS FOR OSTEOGENESIS. This research is being driven by the need for a scaffold for orthopaedic reconstruction that provides controlled release of growth factors to enable rapid healing. None of the current systems possess the required combination of properties to enable new tissue to regenerate rapidly. The aim of this project is to design a system for sustained drug release using block copolymer micelles to encapsulate growth factors and then polymerising the micelles in a biodegradable polymer scaffold. This would enable local delivery of osteogenic growth factors to a bone defect.Read moreRead less
Hypoxia-mimicking bio-scaffold for skeleton regeneration. The project is to develop bioactive bone grafts to improve bone repair and shorten the recovery time of patients with fractures, degenerative joint diseases, and bone cancer and bone deformities.
The development of new scaffolds for bone repair comprising polycaprolactone and strontium-substituted bioactive glasses. The drive to develop bone grafts to fill major gaps in the skeleton, whilst circumventing the need to use permanent implants has led to a major research thrust towards developing biomaterials for bone-tissue engineering. The project will develop scaffolds with highly osteoconductive bioactive glasses in a polymer matrix for bone regeneration applications.
Intelligent scaffolds and methods for repair of osteochondral defects. Osteoarthritis (OA) produces articulation of bone against bone resulting in extreme pain and disability. Of all musculoskeletal disorders, osteoarthritis has the greatest social and economic implications worldwide. By 2030, it is projected that 9.3% of the adult population will suffer from arthritis, significantly affecting their quality of life and overall productivity. A tissue engineered product capable of repairing osteoc ....Intelligent scaffolds and methods for repair of osteochondral defects. Osteoarthritis (OA) produces articulation of bone against bone resulting in extreme pain and disability. Of all musculoskeletal disorders, osteoarthritis has the greatest social and economic implications worldwide. By 2030, it is projected that 9.3% of the adult population will suffer from arthritis, significantly affecting their quality of life and overall productivity. A tissue engineered product capable of repairing osteochondral defects that does not require revision over time but becomes fully integrated with the host tissue will have significant benefits. It will improve patient activity and quality of life, and significantly reduce current health care costs associated with osteoarthritis sufferers.Read moreRead less
Smart Matrix™ approaches towards neo vascularisation in bone repair. Bone injuries cost Australia more than $1 billion annually. The development of a medical device combining novel pro-angiogenic technology, Smart Matrix™, with polymer scaffolds for treatment of bone defects by this project, will facilitate rapid development of a blood supply within the defect, aiding bone growth and reducing overall costs compared to current treatments.
Elucidating surface-mediated permissive cues for cellular differentiation. This project will develop a novel biomaterial platform technology that will enable firstly the probing and thereafter the control of the cellular pathways of adult mesenchymal stem cells. These fundamental insights will be translated into novel stem cell culture ware products that will enable clinically relevant, functional tissue repair and regeneration.
Controlling the adhesome to regulate cell fate on biomaterials. Mesenchymal stem cell-based tissue engineering practices are hampered worldwide by the lack of appreciation and understanding of the matrix-mediated cues that must be provided during adhesion and spreading to drive cells to definitive tissue end points. This project will address these knowledge deficiencies by combining high throughput array technologies, a set of tailorable self-assembling biomaterials and real-time biosensors to r ....Controlling the adhesome to regulate cell fate on biomaterials. Mesenchymal stem cell-based tissue engineering practices are hampered worldwide by the lack of appreciation and understanding of the matrix-mediated cues that must be provided during adhesion and spreading to drive cells to definitive tissue end points. This project will address these knowledge deficiencies by combining high throughput array technologies, a set of tailorable self-assembling biomaterials and real-time biosensors to rapidly, at high resolution, elucidate how mechanotransductive cues determine the fate choice of mesenchymal stem cells, and furthermore, how to manipulate them with smart biomaterial design to achieve desired outcomes for tissue engineering.
