Ischemia was associated with loss of Olig-2-positive oligodendrocytes and an increase in Iba1-positive microglia in the intragyral white matter of the first and 2nd parasagittal gyrus and periventricular white matter compared with sham control (p < 0.05), with no significant difference between the ischemia-vehicle and ischemia-hAEC groups (p > 0.05, Figure 3 and Figure 5). Here, OLIG2 is linked to ischemia.
