Figure Lengend Snippet: (A –X) Serial sections taken 25 μm apart from tissue cleared mouse temporal bones showing the entire AN within the cochlea and the AN GTZ in a young (3 months) (A-L) and an aged (2.5 years) (M-X) CBA/CaJ mouse. (D’, E’, I’) Enlarged images of the white outlined regions of the AN GTZ in a young mouse are shown. (P’, T’, V’) Enlarged images of the white outlined regions of the AN GTZ in an aged mouse are shown with a white arrow indicating CD68 + cells within the AN, while no CD68 + cells were seen in the AN of the young mouse (D’, E’, I’). Dashed white lines in D’, E’, I’, and P’ show the cone-shaped morphology of the AN GTZ. Dashed white lines in T’ and V’ show the GTZ in the basal turn/hook of the cochlea. Each mouse temporal bone was stained with Myelin Basic Protein (green) and CD68 (red). Scale bars = 200 µm for all images.
Article Snippet: To quantify age-related changes in myelination in the AN, we measured the volume and surface area of myelinated fibers in young (3 - 4 months) and aged (≥ 2.5 years) CBA/CaJ mice using Imaris.
