(A) Confocal analysis of hypoxyprobe-1 (pimonidazole)-positive hypoxic (O2 <10 mm Hg) tissue in the hippocampus of 8 month old Pdgfrβ+/+, Pdgfrβ+/− and F7 mice.
(B) Quantification of hypoxyprobe-1-positive area expressed as a percentage of total tissue area in the cortex and hippocampus of 6–8 month old Pdgfrβ+/+, Pdgfrβ+/− and F7 mice. A total of 36 and 24 randomly chosen fields (420 × 420 μm) from 6 non-adjacent cortical and hippocampal sections, respectively, were analyzed per mouse. Mean ± s.e.m., n=6 mice per group; *p<0.05 or **p<0.01 by one-way ANOVA. (See Fig. S7).
