GFAP and brain ischemia: The ischemic cerebral cortex showed a significant increase of proliferative microglia/infiltrated macrophages (in red-CD11b and blue-Ki67; Figure 4) at day 7 in comparison to control brains followed by a slight decrease at day 14 and a sharp decline at day 28 after ischemia (p < 0.001, Figure 6A), In contrast, the number of proliferative astrocytes (in green-GFAP and blue-Ki67; Figure 4) showed pseudo-control values at day 7 followed by a mild non-significant increase at 14 and 28 days after cerebral ischemia (Figure 6A).
