Abstract/ Summary
Inner ear organoids represent a potentially inexhaustible source of otic tissues, including sensory hair cells and supporting cells, for in vitro manipulation. Here, we present a protocol for labeling S-phase entry of cells in inner ear organoids using 5-ethynyl-2′-deoxyuridine (EdU), followed by fixation and vibratome sectioning. Nuclear EdU is then detected alongside protein markers of interest via immunofluorescence. This workflow enables the visualization of cell and tissue morphologies within developing organoids and assessment of how different manipulations affect cell proliferation.
