Preservation of OHCs’ structural organization during culturing period. (A) Light micrograph of an acutely dissected OHC. (B) Same OHC as in (A) demonstrates well preserved CA1, CA3, and DG hippocampal regions at 8 DIV. Higher magnification of CA1 (C) and DG (D) regions of cresyl violet-stained OHC at 8 DIV also illustrate intact hippocampal cytoarchitecture. Serial imaging of PI-stained OHC at 1 (E), 5 (F), and 8 (G) DIV demonstrates recovery of slice from procedure-related cellular degeneration. Scale bars (A,B) 500 μm; (C,D) 50 μm; (E–G) 500 μm.
