| abstract |
Myoblasts are produced, conveniently in low or serum-free medium, for use in introduction into a mammalian host, particularly a human host, for treatment of diseases of muscle tissue or acting as carriers for genetic capabilities, particularly correcting a genetic defect or for production of a soluble protein, which may serve in a therapy for the mammalian host. Myoblasts introduced into tissue are able to migrate to sites distal from the site of injection, expanding the area of their effect. |
