Scanning electron micrographs of utricles of postnatal 14 days old miniature pigs (otoconia was removed for a better view). a (1): low magnification image of the utricle from wild miniature pig with numerous hair cells throughout the sensory epithelium; a (2): high magnification image of the utricle region from wild miniature pig; b (1): low magnification image of the utricle from MITF-mutation porcine model with numerous hair cells throughout the sensory epithelium; b (2): high magnification image of the utricle region from MITF-mutation porcine model. Scale bars = 1 mm in a (1) & b (1). Scale bars = 60 μm in a (2) & b (2)
