| Research Abstract |
Polyplex nanomicelle is an effective and biocompatible gene carrier. By hydrodynamic injection of nanomicelle into skeletal muscle of mice, a prolonged transgene expression was obtained for more than a month. The addition of chondroitin sulfate to the nanomicelle further reduced the tissue damage in the muscle. In model mice of peripheral nerve injury, the introduction of IGF-1 gene into the muscle using the nanomicelle accelerated the recovery of motor function and sensation of the paralyzed limb, through the processes of the muscular hypertrophy induced by IGF-1. This strategy is promising for avoiding disuse atrophy and the eventual early recovery of motor and sensory functions after severe trauma.
