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

Summary
Early developmental influences on neocortical organisation. This project seeks to identify the influence of preceding developmental stages on the correct formation of the brain. Development is a sequence of transformations where every stage depends on the outcome of previous stages. The project intends to examine how the early sensory periphery, early-born brain circuits, and intrinsic neuronal interactions affect the subsequent organisation of the cerebral cortex – a mammal-specific brain regio ....Early developmental influences on neocortical organisation. This project seeks to identify the influence of preceding developmental stages on the correct formation of the brain. Development is a sequence of transformations where every stage depends on the outcome of previous stages. The project intends to examine how the early sensory periphery, early-born brain circuits, and intrinsic neuronal interactions affect the subsequent organisation of the cerebral cortex – a mammal-specific brain region responsible for perception, motor planning and cognition. It expects to provide novel mechanistic and conceptual insights into the process of normal brain development and more general biological phenomena, such as development and evolution. It may also provide insights into several genetic and non-genetic causes of brain malformations.Read moreRead less

Recent advances in tissue engineering have opened up opportunities for the generation of synthetic tissues but these studies have also highlighted a fundamental knowledge gap in our understanding of how complex tissues mature to prepare for life as an adult. Much is known about the molecules that control early embryonic development but little is known about the molecules that control maturation after birth. This project aims to build new knowledge that is expected to improve our ability to generate mature heart muscle cells for stem cell applications, tissue repair and regeneration.Read moreRead less
Mobile DNA activity in the mammalian primordial germline. Early in pregnancy, a handful of cells in the embryo become primordial germ cells (PGCs). These PGCs will eventually give rise to sperm or egg cells, representing a critical inter-generational genetic link. Mobile DNA sequences target PGCs to create new heritable genetic changes. This proposal aims to analyse the activity, regulation, and consequences of mobile DNA activity in PGCs.

Glucocorticoid receptor-αD1 modulates stress and inflammation . Environmental stressors in mammalian pregnancy often cause inflammation in the mother which has an adverse effect on the fetus and its survival. The current grant aims to examine the mechanism by which stress and inflammation coexist in pregnancy because stress hormones normally exert anti-inflammatory actions. Contrary to convention, a new glucocorticoid receptor (GR), GRalpha D1, is linked to increasing inflammation. Using innova ....Glucocorticoid receptor-αD1 modulates stress and inflammation . Environmental stressors in mammalian pregnancy often cause inflammation in the mother which has an adverse effect on the fetus and its survival. The current grant aims to examine the mechanism by which stress and inflammation coexist in pregnancy because stress hormones normally exert anti-inflammatory actions. Contrary to convention, a new glucocorticoid receptor (GR), GRalpha D1, is linked to increasing inflammation. Using innovative molecular biology approaches, GRalphaD1's function will be examined to provide a deeper understanding of how stress regulates inflammation in animal reproduction. The project aims to enhance interdisciplinary collaborations with expected benefits including a paradigm shift in our knowledge in this field.Read moreRead less
Foundations of a good egg: correctly transitioning from mitosis to meiosis. Production of viable offspring is essential to the survival of any species. In all sexually reproducing species, this requires a unique cell type, the germ cell. Germ cells undergo a special type of cell division, called meiosis, so that they can eventually produce gametes (sperm in males and eggs in females). This project aims to discover how germ cells halt the standard form of cell division, called mitosis, and initia ....Foundations of a good egg: correctly transitioning from mitosis to meiosis. Production of viable offspring is essential to the survival of any species. In all sexually reproducing species, this requires a unique cell type, the germ cell. Germ cells undergo a special type of cell division, called meiosis, so that they can eventually produce gametes (sperm in males and eggs in females). This project aims to discover how germ cells halt the standard form of cell division, called mitosis, and initiate meiotic division instead. It is important to understand all the fundamental processes that occur during normal germ cell development so that, in the future, we can use this knowledge to support agricultural advances, rescue endangered species and solve human problems such as infertility and genetic disease.Read moreRead less
How do mammalian germ cells transition from mitosis to meiosis? This project aims to determine how germ cells are regulated in the mammalian embryo. Germ cells go on to form the sperm and eggs and are, therefore, critical for reproduction. In particular, this project expects to generate new knowledge about the process of meiosis, a cellular process that is specific to the germ cells. Expected outcomes will inform efforts to control fertility and infertility in livestock, humans and other mammali ....How do mammalian germ cells transition from mitosis to meiosis?
