Methods for increasing the patency of biodegradable, synthetic vascular grafts are provided. The methods include administering one or more cytokines and/or chemokines that promote outward tissue remodeling of the vascular grafts and vascular neotissue formation. The disclosed methods do not require cell seeding of the vascular grafts, thus avoiding many problems associated with cell seeding. Biodegradable, polymeric vascular grafts which provide controlled release of cytokines and/or chemokines at the site of vascular graft implantation are also provided.

Compositions and methods for promoting patency of vascular grafts

The present invention relates in part to compositions and methods for treating a wound, or location of interest, in mammal by administering a decellularized extracellular matrix (ECM) lacking thrombospondin-2 (TSP-2-null ECM). In certain embodiments, the invention provides an acellular composition comprising a decellularized TSP-2-null ECM. In certain embodiments, the invention provides a tunable hydrogel comprising a decellularized TSP-2-null ECM. The invention also provides, in certain embodiments, methods for accelerating cellular migration, methods for enhancing cellular invasion, methods for enhancing vascular growth and maturation of a region to be treated, and/or methods for enhancing a wound repair in a mammal in need thereof.

Compositions and methods useful in regenerative medicine

A structure for monitoring and stimulation includes an external power supply unit. The structure also includes an internal hub communicatively coupled to the external power supply unit. The structure further includes a plurality of sensor modules communicatively coupled to the internal hub by a plurality of flexible interconnects. The plurality of sensor modules include three-dimensional (3D) comb sensor devices.

The present invention relates to novel compositions and methods for reducing or eliminating the thrombogenicity of a graft by modifying the graft with a cell-derived extracellular matrix lacking thrombospondin-2 (TSP2-null ECM) to render it non-thrombogenic when transplanted to a subject in need thereof. The invention also provides a method for improving the biocompatibility of a medical device or an implant by modifying the medical device or implant with a cell-derived TSP2-null ECM, whereby the medical device or implant is rendered non-thrombogenic and pro-migratory.
