A, Representative photomicrographs of NeuN+ stained CA3 and CA1 at 14 days PI (scale bar, 100μm). B, Summary of CA3 NeuN+ density. Compared to Sham-CHI, CA3 NeuN+ density is bilaterally decreased in CHI-Saline mice, and decreased in the ipsilateral hippocampus in CHI-MN72 mice. C, Summary of CA1 NeuN+ density. Decreased ipsilateral CA1 NeuN+ density in CHI-Saline mice is prevented by MN72 treatment. An asterisk (*) represents significant differences with Sham-CHI, *p < 0.05, **p < 0.01.
