Regulating Astrocytosis For Appropriate Defence And Repair Of The Brain After Injury

Funding Amount
$562,742.00
Summary
An inflammatory process, designed to clean up cell debris and maintain tissue integrity following brain insult, also results in an astrocytic scar that biochemically impedes nerve repair. After 8 weeks astrocytes switch to become supportive, however once a scar is formed repair is permanently inhibited. Here, we will test the ability of biomaterials to optimise the timing of the necessary inflammatory phase, to encourage repair by converting astrocytes to their tropic phase more rapidly.
Improving Therapeutic Delivery By Understanding Nanoparticle Interactions With Cells
Funder
National Health and Medical Research Council
Funding Amount
$553,152.00
Summary
Nanotechnology has the potential to transform the way we treat many diseases. This project will investigate how nanoengineered particles can be used to improve the effectiveness of vaccines. Nanoparticles can protect the delicate vaccine cargo from degradation, and will be targeted specifically to the cells in the body that most effectively induce the maximum theraputic response. This study will improve our understanding of how nanovaccines work and develop new ways of delivering vaccines.
Evaluation Of Tissue Engineered Decellularised Biphasic Constructs For Periodontal Regeneration

Funding Amount
$578,031.00
Summary
This project aims to regenerate the tissues lost as a result of gum disease. This will be done using scaffolds that replicate the complex structure of periodontal tissues.The scaffolds will be loaded with cells and allowed to mature before the cellular component is removed. The resultant construct is then inserted back into periodontal defects where it will be repopulated by host cells. This approach has the potential to be developed into an off-the-shelf clinical treatment.
Delivering Advanced Electrode Materials To The Clinic

Summary
This research will develop improved electrodes for interfacing neural tissue by combining the expertise of materials scientists and electrophysiologists with medical bionics researchers. This work is expected to deliver improved bionic devices to the clinic in order to treat a variety of disorders from blindness to the control of motor tremor in Parkinson's disease.
Biomaterials For The Direct Reprograming Of Reactive Astrocytes Into Functional Neurons

National Health and Medical Research Council
Funding Amount
$630,500.00
Summary
We will employ peptide inspired hydrogel nanoscaffolds that can be injected into a brain lesion as a single injection to provide chemical and physical support for the surrounding cells. We will utilize various modifications to these materials to reprogram inflammatory cells into neurons, whilst also promoting the survival, maintenance and growth of existing neurons to encourage repair.

Using Mechanotransduction To Regulate Stem Cell Fate In Heart Tissue
Funder
National Health and Medical Research Council
Funding Amount
$385,983.00
Summary
Emerging new interdisciplinary field, mechanotransduction, combines efforts from biology, engineering, and material science to understand how cells sense/feel their surroundings mechanically e.g. soft vs. stiff and transfer these signals to biochemical signalling to initiate cellular changes. This project aims to develop high-throughput hydrogel platform with stiffness patterns to study cellular mechanosensing mechanism and to generate better heart muscle cells for heart stem cell therapy.
Using Stem Cells And Bioengineered Scaffolds To Promote Regeneration Following Necrotic Brain Injury
Funder
National Health and Medical Research Council
Funding Amount
$710,857.00
Summary
A number of injuries, including stroke, result in tissue loss. Consequently promoting repair will require restoration of tissue structure, replacement cells and a supportive environment to promote integration of these new cells. This study will engineer and develop novel scaffolds that can replace tissue whilst additionally providing physical and chemical support for newly implanted stem cells. This work will be conducted in an animal model of stroke.
Novel Biocompatible Nickel-free Shape Memory Alloy Scaffolds For Biomedical Applications
Funder
National Health and Medical Research Council
Funding Amount
$530,789.00
Summary
The current project is aimed at the development of a new class of novel biocompatible nickel-free shape memory alloy (SMA) scaffolds for metallic implant applications. The new scaffolds possess the ability to exert a mechanical force on the surrounding bones, and stimulate new bone tissue ingrowth, due to their shape memory effect, superelasticity and bone-mimicking porous structure. The outcomes from this project will provide innovative implant materials.
Diabetic foot ulcers are a common and costly complication associated with Diabetes. Current treatments are only modestly effective in promoting healing, and in many cases amputation is necessary. Through this project we will develop a new treatment strategy that involves the combination of adult stem cells and powerful signal molecules to promote robust diabetic foot ulcer repair.
