Fig. 2. Irradiation results in upregulation of p21 in neural progenitors (NPCs) in dentate gyrus.

Fig. 2

a There is absence of p21 immunoreactivity in nonirradiated dentate gyrus whereas p21 nuclear immunostaining is apparent in both granule and subgranular cells at 9 weeks after 5 Gy (p21, red; DAPI, blue). b A type-1 cell (arrow) demonstrates p21 nuclear immunoreactivity after irradiation (nestin, green; GFAP, white; p21, red; DAPI, blue). c Some type-2a (Tbr2+/DCX−, arrowhead), type-2b (arrows, Tbr2+/DCX+), and type-3 neural progenitors (open arrow, Tbr2−/DCX+) demonstrate p21 nuclear immunoreactivity (Tbr2, green; DCX, white; p21, red; DAPI, blue) after irradiation
