Keeping forces local for epithelial homeostasis. This project probes how epithelial cells use mechanical forces to communicate with one another in biological life. It tests the novel concept that negative feedback is a critical, hitherto unappreciated dimension in mechanical communication, which acts to ensure proportionate responses for homeostasis. It will generate fundamental new knowledge in biology using an innovative combination of cellular and biophysical experiments and physical theory. ....Keeping forces local for epithelial homeostasis. This project probes how epithelial cells use mechanical forces to communicate with one another in biological life. It tests the novel concept that negative feedback is a critical, hitherto unappreciated dimension in mechanical communication, which acts to ensure proportionate responses for homeostasis. It will generate fundamental new knowledge in biology using an innovative combination of cellular and biophysical experiments and physical theory. The expected outcomes are fundamental new knowledge, interdisciplinary training for young scientists, new national research capacity and growing international collaborations. It will benefit Australia by enhancing its scientific world linkage, status in scientific leadership and research capacity.Read moreRead less
Shear stimulated Brillouin microscopy for cell mechanobiology. This project aims to develop novel technology for non-contact imaging of micro-mechanical properties in cells and tissues to answer fundamental questions of cell mechnanobiology. Based on principles of Brillouin light scattering, the project takes advantage of a radio-frequency lock-in detection scheme. The project will result in a real-time, high-sensitivity, non-contact 3D imaging solution for spatial characterisation of cell's loc ....Shear stimulated Brillouin microscopy for cell mechanobiology. This project aims to develop novel technology for non-contact imaging of micro-mechanical properties in cells and tissues to answer fundamental questions of cell mechnanobiology. Based on principles of Brillouin light scattering, the project takes advantage of a radio-frequency lock-in detection scheme. The project will result in a real-time, high-sensitivity, non-contact 3D imaging solution for spatial characterisation of cell's local stiffness and compressibility. This will underpin the advancement of knowledge in the area of cell mechanobiology and the investigation of diseases, where microscale changes in cell mechanical properties lead to cell dysfunction and apoptosis.Read moreRead less
