Figure 1. Dynorphin A in spinal astrocytes illustrated by immunofluorescence confocal microscopy.

Figure 1

The presence of dynorphin A in spinal astrocytes in primary culture (from rat) was assessed by anti-dynorphin A in immunofluorescence histochemistry using confocal microscopy (panels a and b). Dynorphin A (red fluorescence) is present in astrocytes with GFAP (green fluorescence), a marker for astrocyte cells. Nuclei are stained with DAPI (blue). In panel b, it is noted that an astrocyte contains dynorphin A but not GFAP (Baba et al., 1997). GFAP labels mature astrocytes, and thus immature astrocytes may be present which are not labeled with GFAP (Baba et al., 1997).
