Spatial pattern of galectin-3/Mac-2 immunoreactive cells within the corpus callosum following TBI. Representative photomicrographs illustrating galectin-3/Mac-2-ir cells in the white matter in a TBI animal 24 after injury. Labelling within every 12th serial section is shown. Qualitative assessment shows that the density of galectin-3/Mac-2 labelling is highest at the impact site (panels C and D). Labelling density decreases at levels both anteriorly (panels A and B) and posteriorly (panels E and F) from this site. Bar = 100 μm.
