Multipotent adult progenitor stem cells extracted from bone marrow, and known as MAPCs, have proved to be effective in the regeneration of blood vessel tissue and also in muscle tissue when treating peripheric vascular disease. This was the result of research undertaken with mouse models by two research groups, one by the University Hospital of Navarra jointly with the Centre for Applied Medical Research (CIMA), also of the University of Navarra, and the other by the Centre for Molecular and Vascular Biology atthe Catholic University of Leuven (Belgium). The results of the study have been recently published as an article in The Journal of Clinical Investigation the main author of which is doctor in Biology at the University Hospital of the University of Navarra and CIMA, Xabier López Aranguren. The study was part of a line of research for his PhD thesis. The directors of the current research are doctors Felipe Prósper, for the University Hospital of Navarra and CIMA and Aernout Luttun and Catherine M. Verfaille for the Catholic University of Leuven.
