The present invention provides new compositions and methods to induce therapeutic angiogenesis locally utilizing a collagen binding domain to target an angiogenesis modulating agent. Fusion poly peptides 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 sequence 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 sequence encoding the fusion polypeptide are also provided, as are methods of making the grafts.

La présente invention concerne de nouvelles compositions et de nouveaux procédés permettant d'induire une angiogénèse locale thérapeutique en utilisant un domaine de liaison du collagène pour cibler un agent de modulation de l'angiogénèse. L'invention concerne des polypeptides de fusion contenant un domaine de liaison de collagène lié à un agent de modulation de l'angiogénèse ainsi que des séquences d'acide nucléique codant les polypeptides de fusion. L'invention traite aussi de procédés permettant de modifier localement la circulation en administrant un polypeptide de fusion se composant d'un domaine de liaison du collagène lié à un agent de modulation de l'angiogénèse, ou en administrant une séquence d'acide nucléique codant le polypeptide de fusion. L'invention a aussi pour objet des greffons de tissus dans lesquels un tissu isolé est traité par un polypeptide de fusion se composant d'un domaine de liaison du collagène lié à un agent de modulation de l'angiogénèse, ou par une séquence d'acides nucléiques codant le polypeptide de fusion. L'invention concerne des procédés de fabrication des greffons.
