Do Bone Marrow Macrophages Regulate Leukaemia Stem Cells And Their Response To Treatment?

Funding Amount
$590,103.00
Summary
This project will investigate the role of population of immune cells called macrophages in promoting resistance of leukaemia cells to chemotherapy treatments. As a high proportion of adult patients with acute leukaemia cannot be cured with current treatments, this project could lead to more efficacious therapies targeting macrophages to sensitise leukaemia cells to chemotherapy treatments.
Recipient Bone Marrow Macrophages Contribute To Haematopoietic Stem Cell Transplantation Success

Funding Amount
$608,906.00
Summary
We propose an innovative approach to reduce risk and increase success of blood stem cell transplantation. We will determine whether a specialized cell within the transplant patient is required for donor stem cells to successfully take up residence and recreate the blood and immune system. We will test whether fortifying these specialized cells will improve transplantation outcomes, consequently increasing the number of transplants that can proceed and reducing potentially fatal complications.
Targeting The Hypoxia Sensing Pathway To Improve Hematopoietic Stem Cell Mobilisation And Transplantation

Summary
Transplantation of patients’ own blood stem cells is used to treat many blood cancers. It increases the chance of cure. However the damage caused by chemotherapies used to combat the cancer can compromise stem cell collection and transplantation. Without transplant, these patients are less likely to survive cancer. This project is to test new drugs that enhance the harvest of blood stem cells for transplantation. These will increase the success rates of transplants and cure in these cancer patie ....Transplantation of patients’ own blood stem cells is used to treat many blood cancers.

Using Direct Reprogramming To Generate And Rejuvenate Haematopoietic Stem Cells

Funding Amount
$1,026,313.00
Summary
One of the greatest promises of regenerative medicine lies in our ability to reprogram any cell type of the body into any other cell type. Transdifferentiation is the conversion of one adult cell type to another and it is believed to be the next frontier in regenerative medicine therapies since it can be used in vivo for the direct conversion of one cell type into another. The outcomes of this grant will push the limits of these technologies to generate new regenerative medicine strategies.
Generating Haematopoietic Stem Cells From Human Pluripotent Stem Cells

Funding Amount
$872,215.00
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

Funding Amount
$622,464.00
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.
Twist-1 Inhibits MSC Osteoblast Differentiation During Osteoporosis Via Direct Regulation Of The Wnt Signalling Pathway
Funder
National Health and Medical Research Council
Funding Amount
$482,704.00
Summary
There is a predicted dramatic increase in the number of orthopaedic related problems that require surgical intervention and rehabilitation therapy in the coming decade associated with higher incidences of bone diseases as a consequence of an aging population. This proposal seeks to determine whether the transcription factor, Twist-1 plays a central role in regulating the growth and differentiation of skeletal progenitors during bone loss following the onset of osteoporosis.
Transcriptional Regulation Of Definitive Hematopoietic Development In Humans

Funding Amount
$800,036.00
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.
The intestinal lining is continuously renewed by specialised cells called intestinal stem cells. Stem cells throughout the body are regulated by nearby connective tissues. But, the identity of these supportive cells in the gut are unknown. We test whether a discrete population of connective tissue cells in the gut support intestinal stem cells. This project will identify new cellular therapies and targets to promote intestinal repair and manage intestinal cancer.
