In vivo functional recovery. A Analysis of video gait angles at the toe-off phase. The angles were measured in control and WJ-SCLCs groups for up to 12 weeks following transplantation surgery. B Measurement of the isometric tetanic force at the recovery rate at post-operative 16 weeks. C Microscopic examination of toluidine blue-stained distal sciatic nerve ends at post-operative 16 weeks, showing the histological structures of nerve fiber, axon, and myelin. Scale bar = 50 µm. D, E Total axon count and total axonal area are shown. The mean ± SEM of the ANGs only control group and the WJ-SCLCs-laden ANGs groups are compared (*p < 0.05, Student’s t-test)
