Figure 1From: NG2 and phosphacan are present in the astroglial scar after human traumatic spinal cord injury Examples of CD68-positive macrophage stains obtained from human SCI samples. The densities of the stained profiles are used to reflect the arbitrary rating scale used for semi-quantification used in this study. Transverse sections of human spinal cords stained for CD68 representing, A: a low incidence (arbitrary scale = +) of stained profiles to, D: very high incidence (arbitrary scale = ++++) of stained profiles.Back to article page
