Research Abstract |
To develop the new therapy for the irreversible long nerve deficit, we applied skeletal muscle-derived multipotent stem cell sheet pellets (Sk-MSCSPs), as a novel alternative source of nerve autograft. We used the tubeto the dcellularized conduit (dehydrated esophageal submucous membrane by 70% ethanol). After 4 weeks, conduit was filed by GFP+ cells/tissues, and engrafted GFP+ donor cells/tissues obviously stretch back to proximal portion of recipient nerve. After 8 weeks, theabove properties were more enhanced. These results strongly suggested that Sk-MSCSPs may be the best suitable stem cells for the long nerve gap therapy. Therefore, we want to continue further study with the aim of clinical application.
