This disclosure relates to methods for expanding inner ear supporting cells (e.g., Lgr5+ inner ear supporting cells) and differentiating inner ear supporting cells (e.g., Lgr5+ inner ear supporting cells) to inner ear hair cells (e.g., atonal homolog 1 (Atoh1)+ inner ear hair cells) and the use of the inner hear supporting cells and hair cells, e.g., for identifying candidate therapeutic compounds for the treatment of hearing loss and balance loss. Additionally, the methods described herein can be used in the treatment of a subject having hearing loss and balance loss that would benefit from increased proliferation and differentiation of inner ear supporting cells (e.g., Lgr5+ inner ear supporting cells).
本公开涉及扩增内耳支持细胞(如Lgr5+内耳支持细胞)和将内耳支持细胞(如Lgr5+内耳支持细胞)分化为内耳毛细胞(如阿托纳同源物1(Atoh1)+内耳毛细胞)的方法,以及内耳支持细胞和毛细胞的用途,如用于鉴定治疗听力损失和平衡损失的候选治疗化合物。此外,本文所述的方法还可用于治疗听力损失和平衡失调患者,这些患者将受益于内耳支持细胞(如Lgr5+内耳支持细胞)的增殖和分化。
