CHIR-treated aggregates give rise to inner ear organoids harboring mechanosensitive hair cells

(A-B) Co-localization of two hair cell markers Calb2 and Myo7a (A) or Sox2 and Myo7a (B) in cells lining the luminal surface of a vesicle.

(C) Atoh1/nGFP+ cells also express Myo7a and Sox2.

(D-F) Cells expressing Brn3C, Myo7a, and Atoh1/nGFP exhibit flask-like morphology with a hair bundle on their apical surface characteristic of vestibular hair cells. Some Myo7a+ cells in day 28 samples have faint Atoh1/nGFP expression (arrows), suggesting that these cells are more mature hair cells than cells expressing strong Atoh1/nGFP expression.

(G) The hair bundle marker Espin was observed on the apical surface of Calb2+ hair cells.

(H) Representative voltage-gated currents and mechanosensitive currents recorded from day 25 Atoh1/nGFP+ cells in response to voltage injections and hair bundle deflections, respectively.

(I) A cluster of Brn3A+ neuronal cell bodies were located near Myo7a+ hair cells.

(J) A TUJ1+ neural processes extend and contact Myo7a+ hair cells. (K) The ribbon synapse marker CtBP2 was associated with Myo7a+ cells and TUJ1+ processes.

Scale bars, 10 μm (A-G, I-K).
