B Representative pictures of P28 animals that received BrdU at P3, P7, P14 or P21. For cell type identification of generated progeny, immunostainings against NESTIN (white), GFAP (green), and BrdU (magenta) were performed. rNSCs were identified as NESTIN+/GFAP+/BrdU+ with a radial process (as indicated with arrows), neurons as NESTIN-/GFAP-/BrdU+ cells, and astrocytes as NESTIN-/GFAP+/BrdU+ cells in the hilus, GZ, and ML (arrowheads). Data information: dotted lines label GZ borders; scale bars = 50 µm.
