Understanding how the brain grows and is organised is one of the great challenges of science. This project seeks to identify key regulators of neural progenitors as these are the building blocks from which all brains cells are derived. This knowledge may also identify new avenues through which to manipulate neural progenitor function. This has implications not only for normal brain development but also potential therapies for neural disorders and disease.
Stem cell to differentiation occurs in a bi-directional fashion. Dedifferentiation which allows specialized cells to become stem cells has been found to be important in both cancer and regeneration. In this proposal, we will investigate the metabolic reprogramming of neuronal dedifferentiation. The findings from this study will better inform us on how to specifically target tumours that arise from dedifferentiation.
Promoting Intestinal Stem-cell Mediated Regeneration Following Damage: A Critical Role For Neuregulin 1

Summary
Diseases, infections and pathologies are common clinical problems of the intestine in humans that can lead to loss of intestinal tissue. Individuals with these conditions can experience nutritional problems and severe cases result in death. Promoting regeneration of the damaged tissue is critical to re-establish intestinal function. In this study, we will examine the regenerative potential of a growth factor called Neuregulin1 in the intestine with the aim of facilitating tissue regeneration.

Summary
Skeletal diseases associated with excessive bone loss and skeletal fragility, such as osteoporosis, affect 2.2 million Australians and cost our health system approximately $7.4 billion per annum. Studies from our laboratory suggest a critical role for the mTOR signalling pathway in bone development. Using transgenic animals and state-of-the-art techniques, we will investigate the role of mTOR in pre- and post-natal skeletal development. Results from these studies may provide novel approaches to ....Skeletal diseases associated with excessive bone loss and skeletal fragility, such as osteoporosis, affect 2.2 million Australians and cost our health system approximately $7.4 billion per annum.

Summary
Neural crest cells are specialised stem cells that give rise to many tissues and organs during embryonic development. We recently identified an essential role for a regulatory protein in neural crest cells. Our research is aimed at understanding how this protein influences the growth of structures such as the heart and facial skeleton. Understanding these processes underpins the ultimate goal of implementing diagnostic and preventative medicine for highly prevalent congenital birth defects.

Blood stem cells are long-lived and can give rise to every cell type of the blood system and due to these properties they are currently used in the clinics. Despite their importance, our knowledge of the mechanisms the control the multiplication of these rare cells is very scarce. This proposal aims to identify key factors that have the potential to convert mature, easy available blood cells into stem cells.

Investigating The Formation And Utility Of The Prenatal Platelet Forming System

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.

Summary
Stem cells are responsible for producing and replenishing the ~200 specialised cell types in our body. Our goal is to understand the molecular switches that control the function of these cells. We recently discovered that the activity of certain genes within stem cells is controlled by degradation. This degradation is absolutely crucial for safeguarding the function of stem cells. This project will investigate how this novel mechanism is controlled within these cells.
