Abstract: Provided herein are compositions and methods for binding outgrowth endothelial cells (OEC). The compositions consist of peptide ligands capable of binding OEC with high affinity and specificity. The compositions of the invention include peptides set forth in SEQ ID NO: 1-38 and variants and derivatives thereof. Compositions also include the nucleotide sequences encoding the peptides of the invention. The compositions find use in methods for the isolation of OEC and for the recruitment and retention of OEC to sites of therapeutic interest. Methods for the identification and isolation of other peptides capable of binding OEC are also provided.

Abstract: A radiation-curable prepolymer of a polyurethane endtipped with an hydroxy (acrylate or methacrylate) is disclosed. The polyurethane is derived from the reaction of a polyfunctional isocyanate with a hydrolyzable oligomer of an anhydrous cyclic ester of an hydroxy acid. Crosslinked polymers prepared by irradiating the prepolymers are also disclosed. The crosslinked polymers are bioabsorbable and biocompatible with bodily tissue, yet still maintain the outstanding mechanical properties one would expect from a polyurethane. The prepolymers and crosslinked polymers are especially well-suited for the fabrication of surgical devices, particularly wound closure devices such as surgical staples and clips, in a stereolithography apparatus.

Abstract: Polysiloxane-containing polyurea and polyurea urethane block copolymers and devices formed therefrom are biocompatible and demonstrate improved physical and mechanical properties. The pre-reaction of an amine-terminated polysiloxane soft segment with an organic diisocyanate provides an oligomer that enhances the hydrophilic properties of the copolymer.

Abstract: Modified-polyurethane block copolymers and devices formed therefrom demonstrate excellent biocompatibilty and improved physical and mechanical properties. In a preferred embodiment, from about 5 to about 25 percent of urethane hydrogen atoms are replaced with propyl sulfonate and propyl carboxylate groups to provide the modified copolymer.
