Normal inner ear structure in <i>Mcph1^tm1a/tm1a</i> mice.

<p> (A) Scanning electron microscope (SEM) showed normal development of hair cells at P4 in <i>Mcph1^tm1a</i>^/<i>tm1a</i> mice (<i>Mcph1⁺</i>^/<i>+</i>, n = 3; <i>Mcph1^tm1a</i>^/<i>tm1a</i>, n = 3. scale bar, 10 µm). (B) HE slides displayed comparable structure of inner ears (basal turn) in <i>Mcph1⁺</i>^/<i>+</i> and <i>Mcph1^tm1a</i>^/<i>tm1a</i> mice at 4–5 weeks old (<i>Mcph1⁺</i>^/<i>+</i>, n = 3; <i>Mcph1^tm1a</i>^/<i>tm1a</i>, n = 3. scale bar, 50 µm).
