Summary
Death of insulin-producing cells is a common feature of type 1 and type 2 diabetes, affecting over a million Australians. Although transplantation of cadaveric human islets offers cure, lack of donor islets is a major limitations. An alternative is to find other sources of insulin-producing cells. We are the first to demonstrate that insulin-producing cells are naturally found in human gallbladder. This research proposal will involve detailed characterization of human gallbladder-derived insulin ....Death of insulin-producing cells is a common feature of type 1 and type 2 diabetes, affecting over a million Australians.

Summary
The stem cells in the outer protective layers of the epithelium of the skin (keratinocyte stem cells), possess an intrinsically high capability to regenerate tissue. However, this tissue regenerative ability can be enhanced by interactions with microenvironmental elements i.e. connective tissue cells and proteins. This study seeks to investigate specific keratinocyte-microenvironment interactions which will ultimately be used to improve current methods for generating skin tissue for burns patien ....The stem cells in the outer protective layers of the epithelium of the skin (keratinocyte stem cells), possess an intrinsically high capability to regenerate tissue.

Summary
Bone metastasis occurs in more than 80% of cases of advanced prostate cancer (PCa), and is the major cause of morbidity and mortality in PCa patients. Understanding why PCa cells preferentially metastasize to bone may lead to the the development of novel therapy for inhibiting PCa metastasis. This project will study how the bone cell-secreted protein angiopoietin-1 promotes the metastasis of PCa cells to bone and whether inactivation of this protein can inhibit PCa bone metastasis.
Role Of Amnion Derived Stem Cells In Reducing Lung Fibrosis

Summary
Human amniotic epithelial multipotential cells from the term placenta are being studied in a mouse model of pulmonary fibrosis-emphysema to demonstrate their anti-inflammatory, anti-fibrotic, immune-suppresive and lung repair capability. The availability and numbers of these cells from discarded placentas at birth are unlimited and their potential to repair serious lung disease would have strong clinical interest as a new stem cell therapy.

Summary
Utilising my background in Immunology I will investigate whether specific genetic mutations can create a susceptibility for dysregulation of the flora and immune system within the gut, thus predisposing an individual to inflammatory bowel diseases (ulcerative colitis and Crohn's disease) as well as non-intestinal inflammatory conditions. These diseases are becoming an increasingly prevalent and serious health burden in Australia. We aim to use this knowledge in order to design specific treatment ....Utilising my background in Immunology I will investigate whether specific genetic mutations can create a susceptibility for dysregulation of the flora and immune system within the gut, thus predisposing an individual to inflammatory bowel diseases (ulcerative colitis and Crohn's disease) as well as non-intestinal inflammatory conditions.

Idiopathic pulmonary fibrosis (IPF) is a fatal disease of unknown cause which is unresponsive to current therapy. This study builds on recent work by this group highlighting the importance of a cell signalling molecule called STAT3 in the development of this disease. In particular, two cell types that utilise STAT3 signalling, epithelial cells and B cells, will be examined to see if blocking their STAT3 responses could be a novel therapeutic approach.
MicroRNAs are small molecules that modulate the expression of most genes and so affect nearly every biological process and pathology although, they were only discovered in humans less than 10 years ago. The bottleneck in discovering the functions of miRNAs is in identifying their molecular targets, the majority of which remain unknown. We aim to comprehensively identify direct target genes of epithelial-specific microRNAs and to confirm a number of them by gene target validation approaches.
Haematopoietic Stem Cells From Human Pluripotent Stem Cells: The Future Of Bone Marrow Transplantation

Summary
Blood stem cell transplantation is a vital therapy for patients with leukaemia following chemotherapy or for patients with bone marrow failure. Because many patients lack a donor, there is a need for an alternate source of stem cells. My laboratory will make blood stem cells from human pluripotent stem cells that will treat patients needing a transplant and will be a useful research tool to help us to understand what goes wrong in the blood system in a range of illnesses.
