DCX and brain ischemia: DCX+ cells are rare within the striatum of non-ischemic or normal control brain.14, 15 However, an increase in DCX immunostaining was readily visible in the ischemic striatum at 28 d.p.i. (Figure 2b), indicating that cerebral ischemia stimulates the migration of neuroblasts from the ipsilateral SVZ to the ischemic striatum.
