Loss of calyceal innervations and ribbons of type I hair cells in 24-month-old utricular extrastriola. (A) Co-labeling of calyceal terminals (Tuj1), hair cells (Myo7a) and synaptic ribbons (Ctbp2) in 2 and 24 months old utricular extrastriolar region. (B) Co-labeling of calyceal terminals (Tuj1), hair cells (Myo7a) and type II hair cells + supporting cells (Sox2) in 2 and 24 months old utricular extrastriolar region. Asterisks (*) indicate Sox2 type I hair cells that had lost calyceal innervations in 24-months-old utricle.
