Table 2.

Values of flow cytometry cell cycle analyses of proliferating (S-G2/M) cells stained with propidium iodide. The samples were obtained from control, sham-injured, and injured spinal cord segments. Mean±standard deviation values are indicated in bold. Note that mean values of uninjured and control sham spinal cord segments are significantly different from those obtained from injured spinal cords (P<0.05, as determined by one-sided Wilcoxon rank-sum test)

Injured spinal cord (n=3)	9.07
