The invention provides compositions such modified cells and methods of promoting healing of an injured tissue by enhancing the migration of primary or immortalized progenitor or stem cells and enhancing their engraftment into a target tissue site in mammalian recipient such as a human subject. For example, the cells are adult bone marrow derived cells, such as mesenchymal stem cells (MSC) or hematopoetic stem cells such a endothelial progenitor cells (EPCs) and the target tissue is an injured and/or ischemic heart. |
