| Outline of Final Research Achievements |
We successfully modified a sorbitol-based optical clearing method, ScaleS,for use in high resolution imaging of the entire cochlea, an essential hearing organ within the temporal bone. We reported a tissue clearing-based analytical pipeline for the construction of a single-cellular resolution imaging of the entire cochlea.This method can be completed within two days for the fluorescent protein detection or within three days for immunohistochemistry of endogenous proteins. We generated entire cochlear maps at different postnatal ages with or without noise-induced cochlear damage by recording the cell distribution along the entire longitudinal axis. We next reported machine learning-based pattern recognition automated high-fidelity detection and analysis of total hair cell positions along the longitudinal axis of the organ of Corti.Our method of cellular mapping is highly effective in system-level phenotyping of the organ of Corti under both physiological and pathological conditions.
