Spindles of insect viruses: structure, function and engineering of natural protein crystals as microparticles for vaccine delivery. Protein self-assembly is a critical process participating to the cell architecture and molecular machinery. This project will study the molecular structure of crystals forming in virally-infected cells, a striking example of protein self-assembly, and will engage in engineering of novel crystalline microparticles as antiviral vaccines.
Heparan sulfate complexes with VEGF for control of angiogenesis in tissue engineered constructs. The national/community benefits that will arise from this work include, the generation of knowledge related to the growth of blood vessels in the presence of a synthetic polymer that has been made to look like the natural polymers present in the body. This will lead to an understanding of the underlying mechanisms involved that may have down stream effects relevant to the replacement of many types o ....Heparan sulfate complexes with VEGF for control of angiogenesis in tissue engineered constructs. The national/community benefits that will arise from this work include, the generation of knowledge related to the growth of blood vessels in the presence of a synthetic polymer that has been made to look like the natural polymers present in the body. This will lead to an understanding of the underlying mechanisms involved that may have down stream effects relevant to the replacement of many types of tissues being generated for clinical applications, including possible applications in the treatment of heart disease, the largest killer of people in the Western world.

Blood component interactions with polysaccharide biomaterials for vascular applications. Heart disease is the major killer of people in Australia and the Western world. It is due mainly to the blockage of vessels supplying the muscle of the heart with blood and nutrients, which can be replaced or by-passed but the supply of native vessels in the body is limited. Tissue engineering laboratories have been trying to develop blood vessels for this use for many years without significant success.

It is due mainly to the blockage of vessels supplying the muscle of the heart with blood and nutrients, which can be replaced or by-passed but the supply of native vessels in the body is limited. Tissue engineering laboratories have been trying to develop blood vessels for this use for many years without significant success. This application plans to understand the molecular signals contained within the sugar sequences used in a commonly used biomaterial chitosan that may be used in the construction of synthetic vascular grafts. If we can understand how blood cells interact with this biomaterial, we may be able to develop a blood vessel in the laboratory.Read moreRead less
Pancreatic Differentiation of Cord Blood Stem Cells using Smart Surfaces. Cord blood cells obtained at the time of delivery of a baby are a valuable resource that have the potential to develop into many cell types. This Project entails attaching stem cells derived from cord blood to appropriate 3 dimensional smart surfaces, and examining the ability of such cells to develop into insulin-producing cells. An understanding of how to coax stem cells, seeded on to smart surfaces, to develop into ma ....Pancreatic Differentiation of Cord Blood Stem Cells using Smart Surfaces. Cord blood cells obtained at the time of delivery of a baby are a valuable resource that have the potential to develop into many cell types. This Project entails attaching stem cells derived from cord blood to appropriate 3 dimensional smart surfaces, and examining the ability of such cells to develop into insulin-producing cells. An understanding of how to coax stem cells, seeded on to smart surfaces, to develop into mature cells with different functions will enhance our ability to understand how cells develop. As well, it enhance the potential usefulness of cord blood for research purposes. Read moreRead less
Biochemistry of tropoelastin and elastin. Elastin is the main protein responsible for the elasticity of vertebrate tissues. The Weiss Lab makes large quantities of full-length tropoelastin, which is crosslinked to make elastin. We want to examine the biochemistry of tropoelastin, learn how its domains participate in elastin structure and assembly, and explore cellular responses to our synthetic elastin biomaterial. Remarkably little is known of this biochemistry because elastin is a highly cross ....Biochemistry of tropoelastin and elastin. Elastin is the main protein responsible for the elasticity of vertebrate tissues. The Weiss Lab makes large quantities of full-length tropoelastin, which is crosslinked to make elastin. We want to examine the biochemistry of tropoelastin, learn how its domains participate in elastin structure and assembly, and explore cellular responses to our synthetic elastin biomaterial. Remarkably little is known of this biochemistry because elastin is a highly cross-linked and substantially insoluble macroscopic network of tropoelastin multimers. Our availability of tropoelastin and synthetic elastin now makes these studies possible.Read moreRead less

Summary
Investigation and development of biological anti-adhesive coatings. Lubricin is a biological anti-adhesive protein that is found in mammalian joints. This project will investigate the properties and action of Lubricin and develop novel anti-adhesive coating technologies to eliminate problems associated with non-specific binding of biomolecules in microfluidic and biosensor applications.
Understanding platinum dissolution in biomedical stimulating electrodes. Platinum is the main material used in electrodes for neurostimulators like the cochlear implant. Platinum electrodes can experience dissolution during implantation, which can impact on their function. The mechanisms governing this dissolution process are complex and still not fully understood. This research aims to understand the chemical, electrical and biological factors that impact on platinum dissolution in electrodes. ....Understanding platinum dissolution in biomedical stimulating electrodes. Platinum is the main material used in electrodes for neurostimulators like the cochlear implant. Platinum electrodes can experience dissolution during implantation, which can impact on their function. The mechanisms governing this dissolution process are complex and still not fully understood. This research aims to understand the chemical, electrical and biological factors that impact on platinum dissolution in electrodes. It will also develop new 3D models to simulate conditions in the human body for more rapid testing of electrodes. The new knowledge generated will improve the accuracy of predictions of platinum dissolution, develop new approaches for minimising dissolution, and contribute to reducing need for animal experimentation.Read moreRead less
Development and validation of virtual epithelial cancer models using an integrated modelling and experimental three-dimensional approach. The mathematical and experimental modelling of the human prostate and ovary applying quantitative bioengineering concepts will lead to virtual cancer models. This project aims to validate these multi-scale models to delineate biological and pathological avenues in healthy and disease tissue and improve prevention and treatment of prostate and ovarian cancer.
