Abstract
This invention relates to the production of biomaterials from polymeric collagen (PC) and its seeding with cells and other components of biomaterials. Polymeric collagen is isolated from tissue, suspended in an acidic solution, and then neutralized at low temperature. The neutralized suspension is then seeded with biomaterial components, such as cells, and the polymeric collagen aggregated to form a biomaterial comprising the biomaterial components. Polymeric collagen biomaterials produced as described herein may therefore be useful in a range of tissue engineering applications.
