Figure 6. Analysis of tip links in Tomt mutants.

(A,B) P6 cochlear inner hair cells from (A) Tomtadd/+ and (B) Tomtadd/add mice stained with anti-Cdh23 (Siemens et al., 2004) and phalloidin. (C,D) P7 cochlear inner hair cells from (C) Tomtadd/+ and (D) Tomtadd/add mice stained with anti-PCDH15-CD2 (Webb et al., 2011) and phalloidin. (E,F) P6 cochlear inner hair cells from (E) Tomtadd/+ and (F) Tomtadd/add mice stained with anti-PMCA2 (Abcam) and phalloidin. (G,H) P8 cochlear inner hair cells from (G) Tomtadd/+ and (H) Tomtadd/add mice stained with anti-MYO7A (Proteus) and phalloidin. (I,J) P8 cochlear inner hair cells from (I) Tomtadd/+ and (J) Tom add/add mice stained with anti-Espin (BD Biosciences) and phalloidin. (K,L) P7 cochlear inner hair cells from (K) Tomtadd/+ and (L) Tomtadd/add mice stained with anti-Whirlin (see Materials and methods) and phalloidin. Scale bar in (A) = 5 µm, and applies to (A–L). (M) Tip links from middle region cochlear hair cells from P7-8 Tomtadd/add mice using SEM. Left and middle panels are from inner hair cell, right panel is from outer hair cell. Left panel scale bar = 500 nm, middle panel scale bar = 100 nm and applies to middle and right panels. (N) Quantification of tip-links per stereociliary column from P7-P8 middle region inner and outer hair cells from Tomtadd/+ (IHC n = 10 cells, OHC n = 9 cells) and Tomtadd/add (IHC n = 17 cells, OHC n = 9) mice.
