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. Using a new approach that we have developed, our laboratories will make blood stem cells from human pluripotent stem cells that will treat patients needing a transplant.
Characterization Of HOXA-expressing Human Haematopoietic Cells Generated From Embryonic Stem Cells

Summary
Blood stem cell transplants are used for treating a range of human blood disorders such as leukaemias. However, for many patients, suitable donors cannot be found. We are searching for ways in which embryonic stem cells can be turned into blood stem cells in the laboratory to provide a new source of these cells that could then be used to treat patients.
Transcriptional Regulation Of Definitive Hematopoietic Development In Humans

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, such as human pluripotent stem cells. During development, blood cells are formed from the blood vessel wall, or endothelium. In this project, we will study the regulation of this process in order to more efficiently make human blood cells in the laboratory.
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.
Understanding The Pathogenesis Of Mitochondrial Disease Using IPS Cells

Funding Amount
$640,372.00
Summary
Induced pluripotent stem (iPS) cells are stem cells derived from adult skin cells that can be converted into cell types such as neurons. iPS cells offer great promise in understanding and treating inherited disorders. However, there are concerns that the “epigenetic memory” of iPS cells has not been completely erased, which may limit the utility of iPS cells. We will evaluate and validate the use of iPS technology in mouse and human models of inherited disorders affecting energy generation.
Using Stem Cells And Bioengineered Scaffolds To Promote Regeneration Following Necrotic Brain Injury

Funding Amount
$710,857.00
Summary
A number of injuries, including stroke, result in tissue loss. Consequently promoting repair will require restoration of tissue structure, replacement cells and a supportive environment to promote integration of these new cells. This study will engineer and develop novel scaffolds that can replace tissue whilst additionally providing physical and chemical support for newly implanted stem cells. This work will be conducted in an animal model of stroke.
Leveraging Genomics Strategies To Generate Adult Neurons From IPSCs And Somatic Cells

Funding Amount
$1,593,336.00
Summary
Recent advances have made it possible to derive myriad specialized human cells from stem cells or by directly reprogramming cell identity. However, these derived cells are generally arrested at a fetal developmental stage, and do not mature to function like adult cells. We will use new genomic, epigenetic, cell reprogramming, and manipulation methods to discover how to derive mature cells, aiming to generate mature neurons for use in neurobiology research, disease modeling, and drug screening.
A Stem Cell-specific MicroRNA-independent Function Of Drosha

Funding Amount
$637,702.00
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.
Standardising Protocols For The Differentiation And Integration Of Human Pluripotent Stem Cell-derived Neural Transplants In Parkinson's Disease

Funding Amount
$987,664.00
Summary
Clinical trials have shown that transplanting dopamine neurons (specific nerve cells) into the brain of Parkinson’s disease patients can improve symptoms. Trials use fetal tissue for implantation, which is unsustainable and highly variable. This proposal will examine stem cells as an alternative. We will establish a reliable protocol to instruct human stem cells to become dopamine neurons, develop methods to select these cells and, examine the integration of these transplanted cells in the brain
Defining The Role Of Reserve Stem Cells In Gastric Cancer

Funding Amount
$563,739.00
Summary
Over 800,000 deaths from stomach cancer occur annually. This often fatal disease is caused by chronic inflammation of the stomach lining. This proposal will investigate how stomach inflammation ‘reprograms’ a new type of 'cancer stem cell' to form tumours and evaluate ways to therapeutically target these cells to prevent disease. Collectively, these studies will inform new approaches for stomach cancer prevention and treatment.
