GSK-3 Inhibitor Promotes Neuronal Cell Regeneration and Functional Recovery in a Rat Model of Spinal Cord Injury

Figure 3

FITC fluorescence traces for observing the progression of nerve fiber regeneration in the trauma area (a-c). At 8 weeks after SCI, more positively labeled cortical spinal tract fibers were observed in the TDZD-8 group (d). P<0.05 compared with the PBS and blank groups.
