Figure 2From: CXCL12 in astrocytes contributes to bone cancer pain through CXCR4-mediated neuronal sensitization and glial activation in rat spinal cord Cellular localization of CXCL12 expression in spinal cord dorsal horn of sham and TCI rats. Double staining shows that CXCL12 (red) is colocalized with GFAP (green, middle), a marker for astrocytes, but not with NeuN (green, left), a marker for neurons or IBA1 (green, right), a marker for microglia. Tissues were collected 10 days after TCI. Two single-stained images were merged. Original magnification: 400× for all the confocal images showing the dorsal horn ipsilateral to TCI (bar = 50 μm).Back to article page
