Changes in astrocyte area fraction, microglia, proliferation, and apoptosis. Astrocyte area fraction [glial fibrillary acidic protein (GFAP), panel A], and numbers of microglia [ionised calcium-binding adapter molecule-1 (Iba1), panel B], proliferating cells (Ki67, panel C), and apoptotic cells (caspase3, panel D) in periventricular (PVWM) and parasagittal lower intragyral white matter (LIWM; first and second gyri combined) of the sham-ischaemia (white circles, n = 9), ischaemia-vehicle (black circles, n = 8), ischaemia-Epo (red triangles, n = 8), ischaemia-hypothermia (blue triangles, n = 8), and ischaemia-Epo-hypothermia (green diamonds, n = 8) groups at 7 days after cerebral ischaemia. Data are presented as mean ± SD. Analysis by 2-Factor ANOVA with ischaemia as an independent variable and region as repeated measure, and 3-Factor ANOVA with hypothermia and rEpo treatment as independent variables, and region treated as a repeated measure. *P < 0.05 versus sham-ischaemia; #P < 0.05 effect of rEpo; $P < 0.05 effect of hypothermia.
