Abstract:
Techniques for the production of flow-oriented collagen gels using hydrodynamics to influence the assembly of collagen fibers. Highly concentrated monomeric solutions of collagen are subjected to shear and extensional flow as they are drawn onto a substrate to induce fibrillogenesis under a high Ph buffer. The produced gel captures the flow induced ordering of molecular collagen upon fibril formation. The depositing or the induction of fibrillogenosis occurs without the application of a magnetic field to the concentration of collagen. These highly oriented 3D scaffolds are capable inducing contact guidance and guiding mammalian cell growth. The collagen fibers mimic the construction of in vivo fibers with the characteristic D-periodicity and the integrin receptors on the fibroblasts respond to this organization. The industrial applications of three-dimensional collagen gels as a biomaterial are widespread from drug delivery to burn repair or tissue engineering system.
