We further immunostained for the neuroblast marker, doublecortin (DCX), and observed that 18% of NG2-tdT+ cells at the site of stroke injury and 11% of NG2-tdT+ cells at the site of physical injury were positive for DCX, while less than 1% NG2-tdT+/DCX+ cells were observed at the contralateral side of uninjured cortices (Figure 3D-E). The gene discussed is DNTT; the disease is stroke disorder.
