CX3CR1^GFP/+ Mo/MΦ do not express vascular markers. CX3CR1^GFP/+ cells do not express endothelial (GLUT1) (a), pericyte (PDGFRβ) (b), or smooth muscle cells (α-actin) (c) markers 14 days after MCAo but are positive for the microglia/macrophage marker Iba1 (d). Scale bars represent 50 μm. c Disorganized blood vessel (arrowhead) shows spotty α-actin staining and surrounding CX3CR1^GFP/+ cells (thin arrows), as compared with an adjacent intact vessel (§), which shows uniform α-actin staining and no associated CX3CR1^GFP/+ cells
