NG2 immunoreactivity in GDA^CNTF-transplanted dorsal column injuries. (a) Transplanted hPAP⁺ GDAs^CNTF (arrowheads) at 8 days post injury/transplantation. (b) The same slide stained for NG2 (green) showing that the transplanted cells (arrowheads) show immunoreactivity for NG2. (c) Co-localization (yellow) of NG2 and hPAP immunoreactivity in regions containing higher densities of GDAs^CNTF (arrowheads). In general, regions of the injury site that contained higher densities of hPAP⁺ GDAs^CNTF had a higher density of NG2 immunoreactivity. Scale bars 50 μm.
