th2+ Cells Are Continuously Generated throughout Life
(A) 5 dpf larvae were treated with BrdU for 24 hr and analyzed at 9 dpf. Numerous th2:GFP+ cells (green) are labeled with BrdU (magenta) in the hypothalamic posterior recess. Arrowheads indicate double-labeled cells.
(B) 12 dpf larvae were treated with BrdU for 24 hr and analyzed at 25 dpf. th2:GFP+ cells (green) labeled with BrdU (magenta) can be found in medial regions of the hypothalamic posterior recess. Arrowheads indicate double-labeled cells.
(C) 6 mpf fish were injected interperitoneally with BrdU and analyzed 2 weeks later. th2:GFP+ cells (green) labeled with BrdU (magenta) can be found in a midsagittal view of the hypothalamic posterior recess. Arrowheads indicate double-labeled cells.
(D) Percent of BrdU+ cells in the th2:GFP+ population throughout the entire posterior recess. Error bars represent SEM; n = 5 brains.
Images in (A) and (B) are ventral maximum intensity confocal z projections of the hypothalamic posterior recess. Images in (C) are maximum intensity confocal z projections from midsagittal views of the hypothalamic posterior recess. Individual and merged channels of boxed region are shown in the lower panels. The scale bars represent 10 µM.
