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.
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.
Investigating The Formation And Utility Of The Prenatal Platelet Forming System

Funding Amount
$793,442.00
Summary
A major challenge to regenerative medicine is discovering how to produce useful cell types in the laboratory. Particularly urgent is the need to generate large numbers of platelets, the building blocks of the clotting system, for clinical use. Current laboratory methods are woefully inefficient, thus cannot meet demand. This project aims to discover how platelets are made in nature. With this information we will be able to devise better platelet production strategies in the laboratory.
Role Of The LIM-only Protein LMO4 In Lung Development And Lung Cancer

Summary
Lung cancer is the leading cause of death in cancer patients in Australia. Although treatments have improved in the past 10 years, new therapeutic strategies are eagerly awaited. Deregulation of molecules driving development of normal tissue is often observed in cancer. Our aim is to identify key regulators of lung development and lung repair after injury. We aim to evaluate the role of these molecules in the initiation and progression of lung cancer to identify new targets for therapies.
Creating A Vascularized Human Liver Organoid To Treat Liver Disease

Funding Amount
$696,968.00
Summary
Due to a shortage of donor livers many patients suffering liver failure die before a liver transplant can be arranged. This project will grow human liver tissue (termed a liver organoid) using a specilaized human liver support material in which human liver cells and their specific blood vessels are assembled in the laboratory. The liver organoid will be transplanted into animals with a liver disease similar to a known human liver disease to test if the organoid can cure the liver disease.
