    Research

    This study aims to assess the efficiency and efficacy of delivering in a clinical-like approach the Insulin-like growth factor-1 (IGF-1) pro-peptides for future therapeutic applications in human cardiovascular and kidney diseases. It is based on two important experimental observations from our laboratory: (1) we demonstrated that, in murine hearts, overexpression of one of the splice variants of IGF-1, namely IGF-1Ea pro-peptide, stimulated revascularization and protected against heart failure; (2) we discovered PDGFRa+ MSCs possess a yin-yang innate capacity to revascularize ischemic tissue, but also induce fibrotic diseases if chronically activated. Three critical roadblocks are preventing the clinical translation of these promising discoveries: (1) there are currently no tested or validated approaches for the potential delivery of IGF-1 pro-peptides to humans; (2) knowledge is lacking about the biological function of the other IGF-1 pro-peptides in multi organ functions; and (3) there are no mechanistic insights to manipulate the dual function of MSCs. Our laboratory seeks to directly address these limitations and lay the foundations for the future translation of this approach to attenuate or reverse pathologies in humans.
