Giulio Cossu has a long lasting interest in the field of muscle cell and developmental biology. He discovered the myogenic potential of a bone-marrow derived, circulating progenitor cell (Ferrari et al., Science 1998). He also identified a novel population of vessel associated stem cell, the mesoangioblasts (Minasi et al. Development 2002; Dellavalle et al. Nature Cell Biol. 9, 255, 2007) that proved effective in the treatment of a mouse and dog models of muscular dystrophy (Sampaolesi et al. Science, 2003; Sampaolesi et al. Nature, 2006; Gargioli et al. Nature Medicine, 2008).
