The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Haematopoietic Stem Cell Glycome Regulates Outcome Of Niche Interactions

Summary
Hematopoietic stem cells (HSC) reside in the bone marrow (BM) and make all the cells of the blood system. We have found a factor in the BM which when blocked, puts normal HSC to sleep helping them survive chemotherapy. This means cancer patients should suffer less side-effects from their therapy. This factor also helps leukaemia stem cells (LSC) resist chemotherapy. Inhibitors may a) reduce patient mortality caused by chemotherapy and b) sensitise LSC to chemotherapy enabling long-term cure.
This research aims to understand the early developmental events in human blood cell diversi?cation that generate cells involved in oxygen transport, wound healing and protecting us from cancer and infection. The ?ndings will assist in diagnosing and treating human immune system and blood cell disorders such as leukaemia, chronic infection and autoimmunity through understanding the mechanisms of how normal, healthy blood cells are generated.
Generating Haematopoietic Stem Cells From Human Pluripotent Stem Cells

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.

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.
Niche Regulation Of Normal And Malignant Stem Cells

Summary
Hematopoietic stem cells (HSC) reside in the bone marrow (BM) and make all the cells of the blood system. We study molecules in the BM regulating normal HSC to helping them survive chemotherapy. This means cancer patients should suffer less side-effects from their therapy. Some of these molecule also help leukaemia stem cells (LSC) resist chemotherapy. Inhibitors may a) reduce patient mortality caused by chemotherapy and b) sensitise LSC to chemotherapy enabling long-term cure.
Interactions Between Haematopoietic, Bone, Vascular And Endocrine Systems Control Stem Cell Fate And Mobilization

Summary
Haemopoietic stem cells (HSC) normally reside in the bone marrow (BM) where they make blood and immune cells. We can force HSC to move from the BM into the blood, a process called mobilisation, used to collect large numbers of HSC for transplantation into cancer patients. My research involves identifying factors that control HSC fate within the BM (that is survival, growth, differentiation) and what happens during mobilisation to force them to leave with the aim of improving transplant success.
Haematopoietic Stem Cells From Human Pluripotent Stem Cells: The Future Of Bone Marrow Transplantation

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. My laboratory will make blood stem cells from human pluripotent stem cells that will treat patients needing a transplant and will be a useful research tool to help us to understand what goes wrong in the blood system in a range of illnesses.

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.

Summary
This research aims to identify how stem cells are regulated in the body in order to improve therapies for blood disorders and abnormal bone formation after severe traumas. Targeting molecules that deregulate stem cells will lead to improved treatments for diseases with outcomes including improved treatments for blood stem cell transplantation, improved therapy in cancer patients and reduced complications of spinal cord injuries.
