Dementias affect a large number of Australians each year with the number of patients expected to triple by 2050. As such, there is need to develop a better model of this debilitating disorder to provide improved treatments. Mesenchymal stem cells, are relatively easy to obtain and grow, and are able to produce the key cell types in the brain. We can use these cells to identify the processes that control the production of brain cells, which will likely provide better treatment of this disease.
A Simple Method To Improve Stem Cell Transplant Therapy

Funding Amount
$831,652.00
Summary
Despite the success of hematopoietic stem cell transplantation and years of promise, almost all other stem cell therapies are considered experimental and remain in preclinical or early-phase clinical testing. This study aims to improve the efficiency of stem cell transplantation by manipulating cellular metabolism prior to transplantation, if effective these results may offer hope to patients suffering from a broad range of disorders.

The worldwide market for bone substitutes has been estimated at over US $1 billion annually. The emerging technology of cell based therapy has opened a new window for the treatment of bone defects. This project is to develop gene-activated scaffolds able to induce blood vessel formation thus improving the local nutrition supply, and subsequently stimulating bone formation in bone defects, as well as osteointegration around implant surface.

Identifying, Validating And Exploiting A Novel Dclk1-positive Bipotential Lung Stem Cell

Summary
The discovery of stem cells has changed our understanding and approach to treating chronic diseases. Unlike other organs, the stem cells that maintain and repair the lung remain poorly characterised. I have recently identified a gene that labels a population of cells which contribute to epithelial repopulation of the lung. This project aims to characterise how this population behaves during lung homeostasis and following lung injury, with a view to translating these findings to the clinic.
Adult Stem Cell Transplantation Therapy In Parkinsonian Rat

Summary
Parkinson's disease is a progressive neurodegenerative disorder characterised by slowness of movement, muscle rigidity and tremor. It affects about 1% of the population at age 50 and 10% over age 80. Symptoms are caused by low levels of dopamine, a chemical in the brain that helps control movement. The symptoms increase in severity with time, leading to increasing difficulty in walking, speaking, writing, swallowing and sleeping and increasing the incidence of broken bones from falls. Parkinson' ....Parkinson's disease is a progressive neurodegenerative disorder characterised by slowness of movement, muscle rigidity and tremor. It affects about 1% of the population at age 50 and 10% over age 80. Symptoms are caused by low levels of dopamine, a chemical in the brain that helps control movement. The symptoms increase in severity with time, leading to increasing difficulty in walking, speaking, writing, swallowing and sleeping and increasing the incidence of broken bones from falls. Parkinson's disease is incurable but the symptoms can be controlled with medications that replace the lost dopamine. Medications become less effective as the disease progresses and there is need for new therapies. Worldwide the hunt is on to discover new cell transplantation therapies to replace the dopamine in the brain and to prevent degeneration of the still surviving dopamine cells. Although embryonic stem cells might be useful for such therapies, they raise the risk of tumour formation from the transplanted cells. This aim of this proposal is to test, in parkinsonian rat, a therapy in which adult stem cells from the patient are transplanted into their own brain to provide a new source of dopamine. We have discovered a new and unique source of adult stem cells, the sense organ of smell in the nose. Small samples can be taken through the nose and we can grow these adult stem cells from people of all ages, including people with Parkinson's disease. As adult stem cells they avoid the ethical issues associated with embryonic stem cell transplantation and as cells from the same patient, they are not rejected by the immune system. This is being tested in principle by a world-first clinical trial in which we are taking another cell type from the nose, growing it in the lab, and transplanting into the injured spinal cord in a search for a cure for paraplegia. This project takes the first steps to developing a new treatment for Parkinson's disease using a patient's own adult stem cells.Read moreRead less
Defining A New Player In Atherosclerosis: The Role Of Adventitial Haemangioblasts As An Outside-in Driver Of Plaque Growth And Stability.

Summary
As the underlying cause of heart attack, atherosclerosis is a leading cause of death worldwide. New approaches to treatment are desperately needed and this requires a better understanding of how atherosclerotic plaques form in arteries. This project studies a new population of stem cells that we have discovered in the outer layer of arteries, to determine how they cause plaques to form, so that we can develop new therapies that target these stem cells to more effectively treat atherosclerosis.
Cell Trafficking In A Stem Cell Model For Hereditary Spastic Paraplegia

Summary
Hereditary Spastic Paraplegia (HSP) is a genetic disease passed down in affected families. It is a slowly progressing lower limb paralysis that gradually restricts daily activities until the sufferer is confined to bed. There are no cures. This project investigates patientsÍ stem cells to study how HSP genes cause disease. We will use these stem cells to discover new potential drug therapies.
How Does The Endometrium Regenerate? Role Of Epithelial Stem/progenitor Cells

Funding Amount

Summary
Endometriosis and endometrial cancer are disorders of endometrial growth and regeneration. We recently discovered adult stem cells in the endometrium (uterine lining), which are responsible for its regeneration each month during the menstrual cycle. We aim to examine the role of a molecular pathway in endometrial epithelial stem cell function during endometrial regeneration to identify novel targets for devising more effective non-hormonal therapies for endometriosis and endometrial cancer.
