Fraction of Ki67 positive or TUNEL positive cells was calculated as #positive cells/(#positive cells + #negative cells) in multiple high-powered fields from three brains from each treatment group.
P values were calculated using a two-tailed Fisher’s exact test to compare treatment groups to control (PBS and IgG).
