GFAP and Stroke: To assess whether the failure of vascular remodeling caused by astrocyte ablation affected the restoration of blood flow, we used multi-exposure speckle imaging (MESI) to track blood flow after stroke (n = 8 control mice [n = 5 wild-type+GCV, n = 3 GFAP-TK+saline], n = 8 GFAP-TK+GCV mice).
