ABSTRACT:
The present invention provides new compositions and methods to induce therapeutic angiogenesis locally utilizing a collagen binding domain to target an angiogenesis modulating agents. Fusion polypeptides containing a collagen binding domain linked to an angiogenesis modulating agent are provided, as are nucleic acid sequences encoding the fusion polypeptides. Also included are methods for locally altering circulation by administering a fusion polypeptide consisting of a collagen binding domain linked to an angiogenesis modulating agent, or by administering a nucleic acid sequences encoding the fusion polypeptide. Tissue grafts in which isolated tissue is treated with a fusion polypeptide consisting of a collagen binding domain linked to an angiogenesis modulating agent, or with a nucleic acid sequences encoding the fusion polypeptide are also provided, as are methods of making the grafts.
