The impact of Hyaluronic Acid on growth factor signalling and angiogenesis. Blood vessel development is controlled by growth factor signalling. Vessels are attracted by and migrate along growth factor gradients, and this is controlled by the extracellular matrix (ECM). From the zebrafish model, we have identified a novel gene that modulates the ECM, impacting growth factor signalling and vessel development. The project will explore by what mechanism this gene impacts signalling. It will comprehe ....The impact of Hyaluronic Acid on growth factor signalling and angiogenesis. Blood vessel development is controlled by growth factor signalling. Vessels are attracted by and migrate along growth factor gradients, and this is controlled by the extracellular matrix (ECM). From the zebrafish model, we have identified a novel gene that modulates the ECM, impacting growth factor signalling and vessel development. The project will explore by what mechanism this gene impacts signalling. It will comprehensively define where in the embryo it is required and investigate what cofactors it interacts with to perform its function. Using genetic zebrafish and mouse models as well as cell culture models we will investigate the fundamental biology of this gene.Read moreRead less
Visualising genetic mosaicism during development. Genetic diversity is the variation in DNA sequence among individuals. We now know that there are also differences in the DNA sequences of cells within the same individual, known as genetic mosaicism. The aims of this proposal are 1) to develop a system to visualise genetic mosaicism 2) arising during embryonic development and 3) in the brain, driven by mobile DNA activity. The expected outcome of this proposal is an unprecedented understanding of ....Visualising genetic mosaicism during development. Genetic diversity is the variation in DNA sequence among individuals.

The aims of this proposal are 1) to develop a system to visualise genetic mosaicism 2) arising during embryonic development and 3) in the brain, driven by mobile DNA activity. The expected outcome of this proposal is an unprecedented understanding of the scope and consequences of mobile DNA-driven mosaicism. This work will have significant impacts in developmental genetics and neurogenetics, and has the benefit of introducing an innovative experimental system with the potential to spark international scientific collaboration and recognition.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. This project expects to generate significant knowledge a ....Mobile DNA activity in the mammalian primordial germline.

Summary
Tracing the epigenetic life-history of cells. Each cell of the human body contains identical genetic information that is activated in different ways to form varied cell types. This research aims to develop novel single-cell genomic technologies to explain the origins of different cell types. This project expects to discover the molecular mechanisms through which specialised cell types are formed, which has been difficult to decipher using existing methods. My novel approach will elucidate how a ....Tracing the epigenetic life-history of cells. Each cell of the human body contains identical genetic information that is activated in different ways to form varied cell types. This research aims to develop novel single-cell genomic technologies to explain the origins of different cell types. This project expects to discover the molecular mechanisms through which specialised cell types are formed, which has been difficult to decipher using existing methods. My novel approach will elucidate how a small population of seemingly homogenous cells can give rise to a myriad of types of cells. Tracing the life histories of cells across time should lead to broad applications including in developmental biology, neuroscience and immunology.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
