FIG. 3.

Comparison of the transgenic lines, Atoh1-CreER^TM and Atoh1-CreER^T2. Representative confocal projection images of the apical turn of the cochlea (A) and utricle (B) from Atoh1-CreER^TM;ROSA26^eYFP mice, induced with tamoxifen at P0 and P1. Representative confocal projection images of the apical turn of the cochlea (C) and utricle (D) from Atoh1-CreER^T2;ROSA26^eYFP mice, induced with tamoxifen at P0 and P1. In A and C, eYFP is in white. In B and D, eYFP is in green and the HC marker, myosin VIIa (myo7a), is in red. Scale bars, 100 μm.
