Figure 1. Time course of astrocyte proliferation and morphological changes after stroke.
A) Confocal images of GFAP and Brdu expression in the penumbra from mice at indicated times after PT. B) Brdu+ cell density presented as cell number per mm2 in Region 1(R1) and Region (R2) with an area of 200 μm×200 μm in the L2/3 of the cortex. R1 is located 0–200 μm from the edge of ischemic core, and R2 is located 200–400 μm from the edge of ischemic core (see the left panel of A2). C-D) The density of GFAP+ (C) and GFAP+Brdu+ (D) stained cells in the penumbra. The cells were counted in the penumbral region of 200 μm×400 μm in L2/3 of the cortex located 0-400 μm from the edge of ischemic core. Dash lines separate ischemic core (IC) and penumbra (P). Data were adapted from Li et al., 2014b.
