CRISPR-Cas9 genome editing and super-resolved live cell imaging to study the extracellular microenvironment at the single molecule level

About the Project

The three-dimensional space around and between mammalian cells is filled with a complex network of extracellular matrix (ECM) molecules, which instruct fundamental processes such as cell survival, differentiation and migration, in addition to providing structural support for cells. ECM molecules orchestrate cell behaviour directly, by signalling to cells, and indirectly, by determining the availability and distribution of secreted proteins such as cytokines and growth factors, and by directing the positioning of cells within tissues. The combination, stoichiometry and geometry of the distinct ECM molecules that are released by cells into their surrounding microenvironment vary from site to site during development, tissue damage, infection and disease. The aim of this project is to study the secretion, spatial distribution and assembly of the ECM at the single molecule level in real time and how this changes during infection. CRISPR-Cas9 genome editing, super resolution microscopy and physiological 3D cell culture systems will be combined to generate stable cell lines expressing tagged ECM molecules at endogenous levels. This will allow the generation of stable biological models to accurately study endogenous ECM protein stoichiometries, kinetics, spatial relationships and interactions. There is also the possibility to investigate the release of ECM molecules by non-canonical cell sources such as innate immune cells.

Laboratory Environment and Training Opportunities

The project will be carried out within the Gene Regulation & RNA Biology Group (Division of Biomolecular Science & Medicinal Chemistry) which currently consists of 6 principal investigators and around 25 full time researchers with well-equipped laboratory facilities within the Biodiscovery Institute.
