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.

Regulation Of Brain Development By Members Of The Fibroblast Growth Factor Family

Summary
The brain is the most complex organ in the body. It is made up of many different types of cells broadly classified into two classes called neurons and glia. The growth of the brain from a small population of immature neuroepithelial cells to many different types of neurons and glia is controlled by small potent proteins called growth factors. We understand that many different families of growth factors are involved in the development of the brain but not how they do what they do. We are studying ....The brain is the most complex organ in the body. It is made up of many different types of cells broadly classified into two classes called neurons and glia.

We understand that many different families of growth factors are involved in the development of the brain but not how they do what they do. We are studying the members of one particular family known as the Fibroblast Growth Factor family or FGFs. We want to find out how they instruct young brain cells to grow and divide and turn into mature neurons.Read moreRead less
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.
Hematopoietic Transplants From Autologous Pluripotent Cell Sources
Funder
National Health and Medical Research Council
Summary
This proposal investigates the utility of two types of patient-derived stem cells for transplantation into blood. These are induced pluripotent stem cells that are reprogrammed from specialized tissues such as skin cells, and stem cells derived using the genetic material of oocytes or sperm only ( one-parent embryos). Using the mouse, we are looking at the ability of these cells to form normal blood lineages after transplantation, and to repair blood in a mouse model for beta-thalassemia.
Creating Stem Cell Niches To Repair The Nigrostriatal System

Summary
It has been difficult to treat Parkinson's with stem cells because transplants make to few new cells and form tumors. In other organs, specialized locations called niches regulate the division and maturation of stem cells. By making a niche in the brains of animals with experimental parkinsonism we induced the brain to make new nerve cells and repair the parkinsonism. This is important because it shows how to use cell based therapies to treat neurodegenerative disorders. .
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.
Systematic And Sensitized Screens For Novel Genes That Regulate The Neural Differentiation Of Mouse Embryonic Stem Cells
Funder
National Health and Medical Research Council
Funding Amount
$360,634.00
Summary
Embryonic stem (ES) cells are cells in the embryo that can transform into any cell type. Genes that direct mouse ES cells to transform into cells of the nervous system will be uncovered by selecting a group of likely suspects, and disrupting the DNA sequences of these genes to see whether neural differentiation occurs normally in their absence. The effects of the gene disruptions will be examined in the developing neural system of the mouse embryo.
Using Stem Cells And Bioengineered Scaffolds To Promote Regeneration Following Necrotic Brain Injury
Funder
National Health and Medical Research Council
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.
