Developmental milestones in mouse inner ear formation
Competence of surface ectoderm lateral to both sides of the hindbrain (HB) precedes any cell morphology changes.

A Thickening of surface ectoderm (SE) to form the early placodes (EP) which is primarily driven by Fgf, Wnt and Pax genes. B Invagination of the otic placodes to form the otic pit (OP). C Further development and invagination of the otic pit to form the otic cup (OC) which pinches off from the surface ectoderm. D The separation from the overlying ectoderm gives rise to the otocyst (OT). E Subsequent morphogenesis to finalize the complex 3-dimensional labyrinth which is demarcated into vestibular and cochlear components. |
Sensory epithelia are shown in blue. Abbreviations:
