What does this research mean for the field?

Current genetic reprogramming strategies to restore hearing by converting supporting cells into hair cells yield only immature, nonfunctional cells, indicating that future therapies must suppress supporting cell identity networks in addition to activating hair cell networks. Novelty: ClaimNovelty.SYNTHESIS. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Evaluate recent advances, limitations, and future requirements in genetic reprogramming and gene therapy strategies for biological hearing restoration.

Overview

Narrative review reveals incomplete conversion of supporting cells to functional hair cells during genetic reprogramming, highlighting the need to suppress supporting cell identity networks.

Key Points

Evaluate recent advances, limitations, and future requirements in genetic reprogramming and gene therapy strategies for biological hearing restoration.
Reviewed literature on gene therapy and biological regeneration approaches for sensorineural hearing loss in mammalian cochlear models.
Assessed experimental strategies combining cell-signaling pathway modulation with hair cell-specific transcription factor expression.
Modulating inner ear cell-signaling pathways alone is insufficient to regenerate sensory hair cells in the mammalian organ of Corti.
Delivering hair cell-specific transcription factors initiates partial hair cell identity but yields immature and nonfunctional hair cell-like cells.
Achieving complete conversion into functional hair cells requires simultaneously suppressing mature supporting cell gene networks and activating hair cell transcriptional programs.
