20150118195 | Electro-Mechanically Stretched Micro Fibers and Methods of Use Thereof - The presently disclosed subject matter provides a scalable and electrostretching approach for generating microfibers exhibiting uniaxial alignment from polymer solutions. Such microfibers can be generated from a variety of natural polymers or synthetic polymers. The hydrogel microfibers can be used for controlled release of bioactive agents. The internal uniaxial alignment exhibited by the presently disclosed fibers provides improved mechanical properties to microfibers, contact guidance cues and induces alignment for cells seeded on or within the microfibers. | 04-30-2015 |
20150118747 | ELECTROSTRETCHED POLYMER MICROFIBERS FOR MICROVASCULATURE DEVELOPMENT - An in vitro model system that guides the development of microvasculature, recapitulating the detailed organization of both its cellular and a-cellular components is established. Use of electrostretched fibrin microfibers enables both endothelial layer organization and co-culture of supporting perivascular (mural) cells such as vascular smooth muscle cells and pericytes. The fiber curvature affects the circumferential deposition of endothelial-produced ECM independently of cellular organization and induces deposition of higher quantities of vascular ECM proteins. Further, a luminal multicellular microvascular structure is disclosed. | 04-30-2015 |
