A study today highlighted a new therapeutic technique to repair and rebuild muscle for sufferers of degenerative muscle disorders. The therapy brings together two existing techniques for muscle repair, cell transplantation and tissue engineering - mesoangioblast stem cells delivered via a hydrogel cell-carrier matrix.
A number of conditions can lead to considerable degeneration or loss of skeletal muscle and, since skeletal muscle has a limited capacity for self repair, therapies for muscle reconstruction or regeneration are often necessary. There are currently two ways to rebuild muscle: cell transplantation, whereby stem cells are injected directly into the muscle or arteries, and tissue engineering, whereby cells are embedded on a biomaterial scaffold to reconstruct a whole muscle.
Stem cell transplantation on its own can be limited by poor cell survival, but the authors hoped that the technique in combination with tissue engineering could increase the chances of efficacy for localized disorders of muscle.
