The inner nuclear layer (INL), where the nuclei of the Müller cells (NMC) and also the nuclei of the bipolar cells (NBC) are located, at low magnification (Bar: 2 µm). The cytoplasm nearby the MC nucleus, and the processes of other Müller cells, contain cytoskeletal bundles (intermediate filaments and microtubules) that go around the nuclei of both cell types.
A. The INL zone at a larger magnification. Microtrubules (large arrowheads) and intermediate filaments (thin arrows) are present inside the Müller cell (MC) processes and in the vicinity of the Müller cell nucleus (NMC). Cytoskeletal bundles are going around the NMC and Amacrine cell (Am) process, as well as around the nuclei of the other cells present. Bar: 500 nm
