Figure 4. Scanning electron micrographs of the outer hair cells from the middle cochlear turn of A: P2 Cdh23^v-6J heterozygote (+ +/Cdh23^v-6J +), B:Cdh23^v-6J +/Cdh23^v-6J Pcdh15^av-Jfb mouse, C:+Pcdh15^av-Jfb/Cdh23^v-6J Pcdh15^av-Jfb mouse, and D:Cdh23^v-6J Pcdh15^av-Jfb/Cdh23^v-6J Pcdh15^av-Jfb mouse. Inset shows a close-up view of a stereocilia bundle of a Cdh23^v-6J Pcdh15^av-Jfb/Cdh23^v-6J Pcdh15^av-Jfb mouse. Note the presence of stereocilia links. Scale bars in A-D equal 2 μm; scale bar in inset in D equals 200 nm.
