In ischemia rats, the expression levels of PSD95 and SYN were decreased (F(1, 4) = 477.95, P < 0.01; F(1, 4) = 49.05, P < 0.01), and SHED transplantation increased their expression (F(1, 4) = 125.67, P < 0.01; F(1, 4) = 21.86, P < 0.01) (Figures 4(h)–4(j)). This evidence concerns the gene DLG4 and ischemia.
