Description
<jats:title>Significance</jats:title> <jats:p>Inducing the growth of new blood vessels by specific factors is an attractive strategy to restore blood flow in ischemic tissues. Vascular endothelial growth factor (VEGF) is the master regulator of angiogenesis, yet clinical trials of VEGF gene delivery failed. Major challenges include the need to control the tissue distribution of factor dose and the duration of expression. Here, we developed a highly tunable fibrin-based platform to precisely control the dose and duration of VEGF protein delivery in tissues. Optimized delivery of fibrin-bound VEGF ensured normal, stable, and functional angiogenesis and improved perfusion of ischemic tissues, without genetic modification and with limited duration of VEGF delivery. These findings suggest a strategy to improve both safety and efficacy of therapeutic angiogenesis.</jats:p>
