Cell migration is a critical process during development, tissue homeostasis or immune response. However, de-regulation of migration can lead to severe disease including fibrosis or cancer metastasis. This project aims to study caveolae formation and mechano-signalling associated with cell migration processes using a combination of a photoelectrochemical imaging system (PEIS), cell spreading assays, super-resolution microscopy and knockdown or inhibition of critical molecules in normal and cancer cells. PEIS will be used to monitor changes in membrane charge and permeability and changes in the calcium signalling, while super-resolution microscopy will allow the localisation of caveolae.
