The placenta is an essential organ required for reproduction in placental species. This project aims to elucidate the fundamental biology of SPINT1 in placental development. It will generate new knowledge about whether the spatial and temporal expression of SPINT1 is conserved across several species; cow, sheep, lizard, mouse and human. It will also define the molecular mechanisms by which SPINT1 directs formation, maturation and expansion of the placental exchange interface which is critical for offspring survival.
The project will increase understanding of placental development, enhance collaboration and research knowhow, and promote future applied projects in all species that reproduce via placental support.Read moreRead less
Developing the dunnart as a marsupial model for conservation research. The Australian bushfire crisis of 2020 has taken an enormous toll on our unique wildlife. With no halt in sight to rising global temperatures, more extreme weather events are predicted to increase in frequency and severity. We simply must act now to preserve our unique native mammals in Australia and safeguard against species loss and irreversible declines in genetic diversity.

The Australian bushfire crisis of 2020 has taken an enormous toll on our unique wildlife. With no halt in sight to rising global temperatures, more extreme weather events are predicted to increase in frequency and severity. We simply must act now to preserve our unique native mammals in Australia and safeguard against species loss and irreversible declines in genetic diversity. This project will develop methods for the generation and preservation of stem cells from a range of our most endangered and vulnerable marsupial species. These cells not only allow us to ‘bank’ species and genetic diversity but also provide a route to enabling genetic manipulation, opening up a completely new niche for conservation biology in marsupials.Read moreRead less
Using Drosophila to analyse a master regulator of epithelial homeostasis. Aims:
This proposal aims to use genetic and cell biological analysis of the vinegar fly, Drosophila, to identify the function of the grainyhead gene in intestinal regeneration.
Significance:
This gene is conserved in all animal species and appears to be a master regulator of epithelial tissue development but it is unclear how it can both influence stem cell maintenance and production of functional cell types.
Expected out ....Using Drosophila to analyse a master regulator of epithelial homeostasis. Aims:

We will identify a new mechanism that governs tissue development, and introduce new imaging and genetic technologies to the Australian research community.
Benefit:
We expect potential economic and commercial interest in development of new gene analysis tools and biotechnological tissue manipulation applications.Read moreRead less

Banking on spermatogonial stem cells to safeguard Australian native fauna. Spermatogonial stem cells in the testis are an untapped resource for species conservation. This project aims to characterise metabolic pathways that control spermatogonial stem cell function, and define the conserved nature of these pathways between model species (mouse) and vulnerable Australian native fauna.

Spermatogonial stem cells in the testis are an untapped resource for species conservation. This project aims to characterise metabolic pathways that control spermatogonial stem cell function, and define the conserved nature of these pathways between model species (mouse) and vulnerable Australian native fauna. Expected outcomes of this project include an enhanced capacity to culture koala spermatogonia in vitro, which will be a first step towards using spermatogonial biobanking as a tool to maintain genetic diversity in this species. Outcomes from this study should provide significant benefits in safeguarding our unique Australian native species, which is of particular importance following the catastrophic 2019/20 bushfire season.Read moreRead less

Cellular stress is responsible for widespread inefficiencies in plant and animal reproduction. Using high resolution proteomics and cryo-electron microscopy, this project aims to investigate how plant and animal germ cells respond to environmental stresses that are known to disrupt fertility, and assess two novel strategies to decrease the sensitivity of cells to stress. This project is expected to generate new global knowledge in the area of fertility regulation with the potential to improve the tolerance of crop species to heat stress, prevent economic losses and help to secure future food production. Further, this project has the intended benefit of improving the fertility of animal species that suffer from stress-induced infertility.
