1. A biocompatible composite scaffolding system capable of providing structural support for engineered bone tissue comprising:
- a first biodegradable matrix comprising a synthetic polymer and a naturally derived collagen matrix, wherein the first matrix has a porosity greater than about 50%; and
comprises about 25% to about 75% synthetic polymer;
a population of cells selected from the group consisting of cartilage-forming cells, bone-forming cells and combinations thereof seeded onto the first matrix;
a second matrix comprising a flexible, collagen-containing matrix; and
a population of muscle progenitor cells seeded onto the second matrix;
wherein the seeded second matrix is preconditioned to induce muscle fiber orientation;
wherein the first matrix and the second matrix are joined thereby forming a biocompatible composite scaffolding system.

Abstract
The invention pertains to methods of producing artificial composite tissue constructs that permit coordinated motion. Biocompatable structural matrices having sufficient rigidity to provide structural support for cartilage-forming cells and bone-forming cells are used. Biocompatable flexible matrices seeded with muscle cells are joined to the structural matrices to produce artificial composite tissue constructs that are capable of coordinated motion.
