Abstract
Using connective tissues as starting materials, a method is described for producing matrix particulates. The invention includes an embodiment wherein the matrix particulate are seeded with living human cells or with cells of other species. Further, the invention encompasses fusing the particulates to constitute composites of various shapes, or holding them together in a porous container made of membranous biopolymers. The particulates or composites can be used as tissues for grafting or as model systems for research and testing. The invention also encompasses the spinning of threads in which the matrix particulates are components.
