General Research Interest:
My laboratory focuses on improved definition, detection and bio-medical applications of circulating stem/progenitor cells. The current projects are: 1) Comprehensive detection of endothelial and other progenitor cells in human blood (collectively defined as the 'repairome'), using novel methods inspired from systems biology and cytomics. 2) Identification of biochemical factors, mainly related to redox metabolism, impeding the survival of circulating progenitor cells spontaneously recruited in damaged tissues. 3) Study of the biomechanical factors controlling the traffic of cells in the bloodstream, as limiting the efficiency of cell therapy. In this regard, we defined the cellular resilience to biomechanical stress, based on new computational models that take in consideration the structural role of water. 4) Use of progenitor cells for tissue engineering of peri-implant space. This project proposes a different approach to deal with the ubiquitous 'foreign body' reaction and subsequent fibrous encapsulation affecting implanted biosensors and drug delivery devices: namely, to 'treat' them before impanation with stem/progenitor cells for stimulation of peri-implant neovascularization.
