Constructing an embryo. This project investigates the cellular and molecular mechanisms underlying temporal and spatial organisation in the eutherian preimplantation embryo. It will examine: the relative roles of cell cycle and circadian clocks in developmental timing; the molecular mechanism by which intercellular adhesion patterns influence spatial organisation; the extent to which marsupials use similar timing and spatial localisation mechanisms to eutherians; the impact of in-vitro manipulat ....Constructing an embryo. This project investigates the cellular and molecular mechanisms underlying temporal and spatial organisation in the eutherian preimplantation embryo. It will examine: the relative roles of cell cycle and circadian clocks in developmental timing; the molecular mechanism by which intercellular adhesion patterns influence spatial organisation; the extent to which marsupials use similar timing and spatial localisation mechanisms to eutherians; the impact of in-vitro manipulations over the first 5 days of mouse pregnancy on embryonic temporal and spatial organisation.Read moreRead less
Capturing tissue-specific progenitors from embryos and stem cells. This project aims to delineate the precursor cells in the embryo that give rise specifically to major cell types in the body. The project will use genetic analysis to elucidate the critical genetic activity that underpins the genesis of these precursor cells and to track the trajectory and the scope of cell differentiation. The embryological knowledge will provide insights into the fundamentals of developmental process for gener ....Capturing tissue-specific progenitors from embryos and stem cells. This project aims to delineate the precursor cells in the embryo that give rise specifically to major cell types in the body. The project will use genetic analysis to elucidate the critical genetic activity that underpins the genesis of these precursor cells and to track the trajectory and the scope of cell differentiation. The embryological knowledge will provide insights into the fundamentals of developmental process for generating cellular diversity and enable identifying unique precursors and the evaluation of the efficacy of deriving the biological relevant cell types from the stem cells. This project expects to have a significant impact on the translation to cell production methodology for tissue engineering and bioreactor technology.Read moreRead less
Defining in molecular terms cis-inhibition as a means to inhibit Notch signaling. Normal development of a baby and our health after birth is dependent on how our cells behave. Signals move between cells and within them to tell them what to do. Proteins interacting with other proteins mostly transmit these signals. This research focuses on a protein named Notch and the signals that it transmits. Notch functions in normal processes, such as blood vessel formation; but abnormal signaling causes and ....Defining in molecular terms cis-inhibition as a means to inhibit Notch signaling. Normal development of a baby and our health after birth is dependent on how our cells behave. Signals move between cells and within them to tell them what to do. Proteins interacting with other proteins mostly transmit these signals. This research focuses on a protein named Notch and the signals that it transmits. Notch functions in normal processes, such as blood vessel formation; but abnormal signaling causes and/or contributes to pathological situations such as degenerative disease and cancer. We are working to understand how the Notch signal is made and how to control it when it is abnormal. This will allow new medications to be developed to help people who have cancer and other Notch-related illnessesRead moreRead less
A novel DNA damage repair protein as a regulator of DNA double strand break repair and genome integrity. This project aims to define the function of a novel DNA damage repair protein. These data will provide a better understanding of DNA repair biology and may reveal novel diagnostic and treatment options for many diseases associated with DNA repair defects, including cancer.
Role of Musashi in the regulation of cell cycle proteins. We have identified a protein family that directs cell fate and maintains male fertility. This project will provide new avenues for generation of contraceptives in male animals and to regulate stem cells for production of specialised cell types in biotechnological applications.
How ribosomal protein loss affects cell fate. This project aims to challenge the dogma that the ribosome behaves only as a ‘‘house-keeper’’. Ribosomal protein (RP) mutations should, and often do, result in reduced cell growth and stunted animal development. Depletion of RPs in Drosophila blood cells impair stem cells and cause massive tissue overgrowth. This suggests RPs are involved in cell fate determination, which this project will research using genetic models. As ribosomal function is funda ....How ribosomal protein loss affects cell fate.

Depletion of RPs in Drosophila blood cells impair stem cells and cause massive tissue overgrowth. This suggests RPs are involved in cell fate determination, which this project will research using genetic models. As ribosomal function is fundamental to the development of all living organisms, this work could have wide implications for understanding all biology – from microbes, insects and plants to humans.Read moreRead less
Understanding the potency and role of individual stem cells in the skin using Rainbow technology. To renew itself, the skin and its components rely on the activity of stem cells. This project will define more precisely the role of each individual stem cell by labelling them with a unique colour and following its fate. This project has the potential to change our current view on how the skin maintains and repairs itself.
Enhancing neurogenesis in the adult primate brain. New neurons are robustly generated in the subependymal zone (SEZ) during human development. Thus, the SEZ may represent an endogenous modifiable source of neurons to enhance plasticity and therapeutic potential in the brain. However, despite our preliminary data, SEZ neurogenesis beyond the first months of life is controversial. This project aims to understand changes in the capacity for human SEZ proliferation from birth through to ageing and w ....Enhancing neurogenesis in the adult primate brain. New neurons are robustly generated in the subependymal zone (SEZ) during human development. Thus, the SEZ may represent an endogenous modifiable source of neurons to enhance plasticity and therapeutic potential in the brain. However, despite our preliminary data, SEZ neurogenesis beyond the first months of life is controversial. This project aims to understand changes in the capacity for human SEZ proliferation from birth through to ageing and whether neurogenesis may be induced by inflammation in the adult. Using transcriptomics we will also determine how the neurogenic environment changes with age/inflammation. This project is an important step in proving that the brain's potential to generate new neurons extends beyond infancy.Read moreRead less
