ASCL1 and stroke disorder: We found that the number of Ascl1+ cells was higher in the striatum, not including the subventricular zone, of the stroke side (121 ± 57cells/section; n = 5) compared to the contralateral uninjured striatum with Rbpj deletion only (37 ± 25/section; n = 5, p = 0.015) (Figure 2A).
