Bone cells and matrices in orthopedic tissue engineering.

The ability to harvest and manipulate osteogenic cells gives clinicians the opportunity to harness capacity of these cells for targeted regeneration and repair of skeletal tissues. Further opportunities to optimize use of cells exist in the ability to design specialized matrices that act as conductive scaffolds. Realization of the full potential of engineered matrix materials and cell-matrix composites can provide new solutions to many clinical problems in skeletal reconstruction.
