Figure 1. Morphological analysis of the inner ear of Sox9-depleted tadpoles at stage 52. Representative cases of the membranous labyrinth of Sox9-depleted tadpoles inner ears (Sox9MO; 2.5 ng) at stage 52 are shown after injection with latex paint. The overall architecture of the inner ear of these tadpoles has been divided into four classes: Class I, normal inner ear structure; Class II, abnormal semicircular canals and utricle; Class III, semicircular canals and utricle absent, saccule reduced in size; Class IV, no inner ear. aa, anterior ampula; asc, anterior semicircular canal; acr, anterior cristae recess; apr, amphibian papilla recess; bp, basilar papilla; ha, horizontal ampula; hsc, horizontal semicircular canal; psc, posterior semicircular canal; pcr, posterior cristae recess; s, saccule; u, utricle; um, utriclar macula.
