| Figure 1: Gene therapy with VEGF and G-CSF enhances sciatic nerve regeneration. Semithin (A and B) and ultrathin (C and D) cross sections of regenerating sciatic nerves 6 weeks after injury. Observe in A, the control, dispersed groups of myelinated fibers, while treated animals (B) present a more organized regenerating nerve with several myelinated fibers. (C) Control group exhibits smaller myelinated fibers in comparison to gene therapy treated group (D). |
