Abstract: The present disclosure provides pro-angiogenic proteoglycan mimetics that can provide a provisional, pro-angiogenic scaffold to support tissue regeneration while limiting systemic exposure to VEGF activity. These mimetics can protect a collagen matrix from rapid degradation, and in conjunction with EPCs promote angiogenesis in order to accelerate ischemic wound healing. For example, the provided compounds can be delivered from the end of a catheter following balloon angioplasty to coat the collagen exposed areas, prevent platelet binding and thrombosis, support capture of EPCs from blood to facilitate reendothelialization, and reduce late-lumen loss (neointimal hyperplasia).
