Figure 5.

Levels (a) of chondroitin sulfate proteoglycan (CSPG, 150 and 70 kDa molecular weight forms; see text for details), detected by western blot, in the ventral region of the lumbar spinal cord of Sham, Saline, and PEDF groups 6 weeks after surgery. Values of the relative optical density of the signal in the bands were expressed as a percentage of the Sham group. Mean ± s.e.m., n = 6–8. The representative bands are illustrated in (b). α-tubulin (50 kDa) was used as sample loading control. *(P < 0.05) when the Saline or PEDF groups differ from Sham, according the one-way ANOVA followed by Tukey posttest.
