FIG. 4.
Induced nitric oxide synthase (iNOS) modulation. iNOS content in the L4–L6 dorsal horn spinal cord 14 days from lesion and 7 days after injection of 1×106 hASCs. iNOS protein content was detected by western blot analysis. The density mean value of the vehicle-injected sham-operated mice within a single experiment was set to 100, and all the other values were expressed as percentage versus the levels detected in sham-operated mice. Each value represents mean±SEM of 6–8 mice. *P<0.05 versus sham+vehicle group; °P<0.05 versus CCI+vehicle.
