Story summary

The team uncovered a rare cochlear supporting-cell subpopulation that converts into sensory hair cells when Notch signaling is blocked.
Prof. Karen Avraham’s Tel Aviv University group reported the discovery in Science Advances, confirming inner-ear regeneration with imaging and multi-omics after Notch inhibition.
The U.S. Food and Drug Administration approved gene therapy for hearing loss, a treatment applied to only a few cases and hindered by high costs and regulatory hurdles.
