Figure 4. Immunofluorescence staining for anti-nucleus and mitotic cell antigen (NUMA) (A, D, G), glial fibrillary acidic protein (GFAP) (B), synaptophysin (E), and chondroitin sulfate proteoglycan (NG2) (H) in sections of spinal cord at the T9 level of animals transplanted with mononuclear cells from umbilical cord blood 1 h after the lesion. Overlapping of the antibodies is represented as: C, NUMA (green) and GFAP (red); F, NUMA (green) and synaptophysin (red); I, NUMA (green) and chondroitin sulfate proteoglycan (NG2) (red). Arrowheads indicate: NUMA-positive cells (A, D, G); positive cells when labeled with GFAP (B), synaptophysin (E), and NG2 (H); double-labeling with NUMA and GFAP (C), synaptophysin (F), and NG2 (I).
