We found doublecortin (DCX)-expressing cells, which migrated into the striatum of stroked Tlx+/− animals (Figure 1b, arrows), which is in agreement with previously reported findings on SVZ neurogenesis after experimental stroke [17], but we did not observe DCX-expressing cells in Tlx−/− mouse brains following stroke (Figure 1b). The gene discussed is NR2E1; the disease is stroke disorder.
