Fig. 4. Hesr1/Hesr2 expression overlaps with p27^kip1.

In situ hybridization of Hesr1 or Hesr2 and other genes expressed in the sensory epithelium were counterstained with p27^kip1 (C–I, E–J). In situ signal was detected in purple, p27^kip1 protein was in red fluorescence. A, C, E, G, I and K: adjacent sections of E13.5 cochlear duct (middle part). Math1 was not yet expressed in this region (K). B, D, F, H, J and L: Adjacent sections of the basal turn (turn1) of an E15.5 cochlea. Scale bar= 100 µm.
