  2. Endothelial Progenitor Cells (EPC)from Biology to Treatment □In 1997, EPC were first identified in adult human peripheral blood □EPC are immature cells capable of differentiating into mature endothelial cells □EPC can play an important role in the formation of new blood vessels - mobilization from the bone marrow - migration through the circulation - incorporation into blood vessels □Clinically, the number and function of EPC have been positively linked with improved endothelial function and regeneration Rosenzweig A., NEJM, 348, 581 (2003).

  4. □ Stimulating endothelialization at the implant surface will restore vascular homeostasis early in the healing process Peptides Immobilized on a Biomaterial Scaffold to Improve Cyto- and Blood- compatibility of Implants Veleva A. et al., Biomaterials, 29, 3656 (2008).

  5. New Functional Tools to Target Tumor Vasculature □Tumor angiogenesis has a critical role in promoting the growth of most carcinomas □ EPC play an important role in angiogenesis-mediated tumor progression □To utilize endogenous EPC as natural vectors to deliver diagnostic and therapeutic reagents to tumors

  6. Market Potential □Regenerative Medicine -cell separations - production of pure cell populations for allogeneic stem cell therapies □Medical Implant Technologiesto treat cardiovascular diseases, “off-the-shelf” products -innovative intravascular stent systems - small diameter vascular grafts - pacemakers - heart valve repair - arterial septal repair implants □Oncology - targeting of tumor-associated blood vessels - non-invasive detection of small cancer tissue, primary tumors & metastases - targeted therapeutics, development of highly specific drug delivery systems - personalized medicine, monitoring efficacy of therapies
