Neurotrophic effects of dental pulp stem cells in repair of peripheral nerve after crush injury

Figure 4 Neural-induced dental pulp stem cells enhance rat functional recovery after nerve crush injury. A: Nerve crush model of peripheral nerve injury and cell sheet implantation; B: Footprints of the four groups; C and D: Analysis of sciatic function index; E: Wet weight ratio of the gastrocnemius muscles; F: Appearance of the gastrocnemius muscle of four groups. Bar = 1 cm. All data represent the mean ± SD. n = 8 in each group. ^bP < 0.01. SFI: Sciatic function index; N-DPSCs: Neural-induced dental pulp stem cells; hDPSCs: Human dental pulp stem cells.
