Activation and inhibition of Notch signaling facilitate proliferative regeneration of sensory cells in adult mice

Eye &ENT Research, EarlyView.
Abstract Due to the limited regenerative capacity in adult mammals, the loss of vestibular hair cells (HCs) leads to balance disorders. In this study, we chronologically reprogrammed adult vestibular supporting cells (SCs) via bimodal regulation of Notch signaling, mimicking dynamic changes in Notch signaling during inner ear development.
