Summary
Macrophages are an important haematopoietic cell type that has been implicated in inflammatory and cancerous diseases. In our preliminary work we have discovered a new macrophage subset, termed the perivascular macrophage, in breast cancer. The aim of this proposal is to investigate the origin of these cells, and the role they play in breast cancer. This will tell us how we might be able to manipulate the functions of these cells in order to curtail breast cancer progression.
Defining The Cellular Basis For Therapeutic Angiogenesis: Characterisation Of Endothelial Progenitor Cell Populations

Summary
Cardiovascular disease is the leading cause of death in the Australia. Endothelial progenitor cells (EPCs), similar to stem cells, have strong self-renewal capabilities and the ability to mature further. There has been immense interest in using EPCs as they are believed to have a role in the growth and repair of blood vessels. This research systematically studies two candidate EPCs, the early EPC and the outgrowth EPC (OEC), and potentially paves the way for using EPCs to treat heart disease.
Progenitor Origin And Regulation In Endometrial Regeneration

Summary
The endometrium is the lining of the uterus and regenerates each month during a woman's reproductive years. Stem and progenitor cells in the endometrium are thought to be responsible for this regeneration. We have identified a genetic marker for stem and progenitor cells in the endometrium of mice and will use this to understand endometrial regeneration. This work will address infertility as well as overactive endometrial growth in diseases such as endometriosis and endometrial cancer.
New Projection Neurons Are Added To The Brain Throughout Life – Identifying Their Source And Function.

Summary
Scientists aim to use our body’s own stem cells to make new nerve cells for brain repair. There are two major types of nerve cell: long range and short range; and until now we did not know how to make new long range nerves. I recently discovered that a special type of brain stem cell, the OPC, makes new long range nerves throughout life. We are building on this discovery by trying to understand the signals that control this process in order to direct OPCs towards nerve regeneration.
A Study Of The Origins Of Macrophages In Healthy And Atherosclerotic Vasculature Focusing On A Novel Population Of Resident Adventitial Macrophage Progenitor Cells (AMPCs)

Summary
White blood cells (macrophages) play a key role in the development of atherosclerosis, the underlying cause of most heart attacks and strokes. We have made new discoveries to show that there are stem (progenitor) cells for macrophages that exist within the outer lining of blood vessels. This project will study whether these local progenitor cells, called AMPCs, are a source of macrophages in atherosclerosis and in turn could lead to new treatment approaches for cardiovascular disease.
Modulation Of BMP Signaling For Enhanced Myelin Repair

Summary
Multiple Sclerosis is the most common neurodegenerative disease affecting young adults. It is a disease that kills myelin cells, which are necessary support cells for neurons and are critical for their function. This research investigates the role that the signal transduction of bone morphogenic protein plays in myelin cell production and myelin repair. Our aim is to identify regenerative therapeutics for Multiple Sclerosis.
Mobilisation Of Endogenous Mesenchymal Progenitor Cells For Growth Plate Regeneration

Summary
Growth plate cartilage is responsible for bone growth in children. Its injury is common and is often repaired undesirably by bony tissue which causes significant bone growth defects. This project will develop a biological treatment through mobilising endogenous progenitor cells to enhance growth plate regeneration and prevent bone growth defects, which will allow patients to avoid highly invasive/costly corrective surgeries.
Defining The Role Of MMP-9-expressing Macrophages In Liver Injury In Chronic Liver Disease

Summary
Defining pathways that lead to fibrosis in chronic liver disease is an urgent priority and unmet need because cirrhosis remains a major cause of death. We will study the development of an additional fibrogenic pathway involving altered liver repair mechanisms, in order to seek ways to restore liver function. New insights arising from this novel research could significantly advance our understanding of how fibrosis develops and lead to new approaches to treat and prevent advanced liver disease.
