Donor organ assessment and reconditioning using ex vivo machine perfusion

Our department has pioneered the development and clinical translation of normothermic machine perfusion as a platform for assessment and reconditioning of donor organs (liver and kidney). We collaborate with PIs in the Department of Surgery (Professor Nicholson and Professor Watson) and support translational research studies utilising NMP as a platform to investigate mechanisms of ischaemia-reperfusion injury of donor organs, establish parameters during machine perfusion that predict optimal organ function after transplantation, and to identify novel therapeutic targets for organ reconditioning and repair. We are particularly interested in novel clinical trials to help translate laboratory findings into clinical practice.
