Abstract
Loss of vestibular hair cells is a common cause of balance disorders. Current treatment options for bilateral vestibular dysfunction are limited. During development, atonal homolog 1 (Atoh1) is sufficient and necessary for the formation of hair cells and provides a promising gene target to induce hair cell generation in the mammals. In this study, we used a transgenic mouse line to test the age and cell type specificity of hair cell induction in the postnatal utricle in mice. We found that forced Atoh1 expression in vivo can induce hair cell formation in the utricle from postnatal days 1 to 21, while the efficacy of hair cell induction is progressively reduced as the animals become older. In the utricle, the induction of hair cells occurs both within the sensory region and in cells in the transitional epithelium next to the sensory region. Within the sensory epithelium, the central region, known as the striola, is most subjective to the induction of hair cell formation. Furthermore, forced Atoh1 expression can promote proliferation in an age-dependent manner that mirrors the progressively reduced efficacy of hair cell induction in the postnatal utricle. These results suggest that targeting both cell proliferation and Atoh1 in the utricle striolar region may be explored to induce hair cell regeneration in mammals. The study also demonstrates the usefulness of the animal model that provides an in vivo Atoh1 induction model for vestibular regeneration studies.

Fig. S1
Atoh1 induction is permanently poised in Foxg1-expressing cells. (A-B) GFP expression (A) under the expression cassette of rtTA-IRES-GFP is permanently activated in cells of the Foxg1-Cre lineage as diagramed in figure 1. At P21, Atoh1 expression reporter, Atoh1-nGFP, is expressed throughout the utricle epithelium including the sensory and transitional epithelia upon induction condition (Dox feeding) (B). Tri-allelic label indicates that the animals carry rtTA, Foxg1-Cre and TgAtoh1 alleles. Scale: 100 μm (A); 25 μm (B). (JPEG 3737 kb)
