Effect of GH on cell proliferation.

<p>(A) 100X images of BrdU and DAPI labeling in the saccules of buffer- and GH-injected zebrafish. (B) Mean (±S.E.) number of BrdU-labeled cells in the saccules, lagenae, and utricles of baseline and buffer- or GH-injected zebrafish. N = 6; * P<0.001. (C) BrdU-labeling in the saccules of baseline, buffer- or GH-injected zebrafish at post-sound exposure day 1 (psed1). Scale bar = 100 µm. Rostral-caudal orientation is the same as <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0028372#pone-0028372-g001" target="_blank">Fig. 1A</a>.
