Figure 7From: CXCL12 in astrocytes contributes to bone cancer pain through CXCR4-mediated neuronal sensitization and glial activation in rat spinal cord Cellular localization of CXCR4 expression in spinal cord dorsal horn of sham and TCI rats. Double staining shows that CXCR4 protein (red) is co-expressed with neuronal marker NeuN (green, left), astrocytic marker GFAP (green, middle), and microglial marker IBA1 (green, right). Tissues were collected 10 days after TCI. Original magnification: 400× for all the confocal images showing the dorsal horn ipsilateral to TCI (bar = 50 μm).Back to article page
