FIG. 5.

FABP5 expression is prominent in sprouting fibers and neural stem cells post-SCI. Confocal microphotographs show that FABP5 protein colocalized with cells and structures that were positive to the growth-associated protein 43 (GAP43⁺) (A and B). Notably, we observed FABP5 expression in neurogenic niches post-SCI, as evidenced by colocalization of FABP5 to GM cells positive to doublecortin (DCX) (C) and WM cells immuoreactive to nestin (D). Scale bars: 20 μm. DAPI, 4′,6-diamidino-2-phenylindole; FABP5, fatty acid binding protein 5; GM, gray matter; SCI, spinal cord injury; WM, white matter.
