Figure 5 - Supplement 1 zpld1a and tectb are primarily expressed in supporting cells. HCR in situ hybridization of 5 dpf myo6b:GFP zebrafish. (A–B) Confocal slices through (A) anterior crista and (B) lateral crista (lateral view) show localization of cabp5b in hair cells and zpld1a in supporting cells. (C) Slice through utricle (dorsal view) shows cabp2b expression in hair cells and tectb expression primarily in the surrounding supporting cells. (D) Slices through saccule (lateral view) at the level of hair cell bodies (top row) and supporting cell bodies (bottom row). cabp2b is primarily expressed in hair cells and tectb is primarily expressed in supporting cells. Scale bars = 10 μm.
