The Material Science of Biomimetic Soft Network Composites. Nature combines stiff and strong collagen fibres intertwined within a weak polymer matrix of proteoglycans into soft tissues with outstanding mechanical durability and biological properties. We converge a biomimetic design strategy inspired in the architecture of natural soft tissues and a novel additive manufacturing technology termed melt electrowriting (MEW) to manufacture advanced biomimetic soft network composites (BSNC).

Nature combines stiff and strong collagen fibres intertwined within a weak polymer matrix of proteoglycans into soft tissues with outstanding mechanical durability and biological properties. We converge a biomimetic design strategy inspired in the architecture of natural soft tissues and a novel additive manufacturing technology termed melt electrowriting (MEW) to manufacture advanced biomimetic soft network composites (BSNC). The SNCs are composed of a weak polymer matrix and a MEW reinforcing fibrous phase printed at the nanometre scale, containing patterns mimicking the natural tissue architectures. Advanced computational tools are applied for the rational design of the SNC while reducing costs and times associated to experimental work.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
Scalable, high throughput microfluidic platforms for tissue specific biomaterials development and tissue genesis. The co-development of novel biomaterial platforms and new generation production methods for tissue analogues will provide the necessary stimulus for improved and more relevant methods of enhanced repair or regeneration of diseased or damaged tissues. These outcomes will result in faster time-to-market new generation therapeutic products for Australia and the world.

Driven by four key nodes across the country, the Initiative aims to bring together geographically and financially separated groups into a critical mass of cell and tissue engineering research. This new and rapidly-growing field uses a bio-synthetic approach to replace, repair or regenerate damaged tissues and organs. The Initiative will build the framework which will enable the Network to: identify appropriate expertise, manage duplication, enhance communication, bring together innovative skill sets, create linkages, generate focussed research programs and foster novel commercial opportunities. Ultimately the Initiative and Network will deliver an improved quality of life, reduced healthcare costs, and increased productivity to Australia.Read moreRead less
Identifying how cortical bone microstructure deteriorates with age. This project aims to define the disruptions responsible for the gradual weakening of the skeleton in ageing by integrating a range of high-resolution imaging, biomechanical, and computational methods.

This project aims to define the disruptions responsible for the gradual weakening of the skeleton in ageing by integrating a range of high-resolution imaging, biomechanical, and computational methods. The expected significance of this project includes a full definition and comparison of the cellular and subcellular organisation of bone from young and elderly individuals. Expected outcomes of this international project include the establishment of a new multidisciplinary research team, and the development of a new data-driven theoretical framework for understanding the nature and the causes of age-related bone fragility. Potential long-term benefits include new ways to treat age-related osteoporosis.Read moreRead less
Design and Fabrication of an Engineered Bone Graft System (EBGS) by combining a composite scaffold and growth factor delivery system. The lifetime risk for long bone fractures in Caucasians over the age of 50 is 17% for women and 6% for men. The prevalence of age-related fractures - and with it higher mortality rates due to complications following bone fractures - is therefore bound to increase over the coming decades. There is clearly a great need for therapies that take age-related changes in ....Design and Fabrication of an Engineered Bone Graft System (EBGS) by combining a composite scaffold and growth factor delivery system. The lifetime risk for long bone fractures in Caucasians over the age of 50 is 17% for women and 6% for men. The prevalence of age-related fractures - and with it higher mortality rates due to complications following bone fractures - is therefore bound to increase over the coming decades. There is clearly a great need for therapies that take age-related changes into consideration, in particular the diminishing capacity of bone to heal with age. In an effort to address the therapeutic challenges of providing bone grafts, we aim to mesh two leading-edge technologies to design and fabricate an Engineered Bone Graft System (EBGS) system.

The clinical demand for bone is massive and to counter this bone can be either harvested from the patient or bone substitutes are used. The success or failure of a bone substitute is determined the instant it come into contact with blood. The surfaces of traditional biomaterials induce a foreign body reaction. The aim of this project is to test the bone forming capacity of a biomaterial that is optimised to produce a natural response from the blood. This response will lead to the formation new viable tissue and eventually bone. Such a material will cause faster bone healing, less pain from graft sites, shorter hospital stays and shorter waiting lists. Read moreRead less
