AFM-based ultrastructural analysis of Caenorhabditis elegans morphology. Nanoscopically resolved exemplary nematode tissues. (a) Height data of the head region of a C. elegans individual. (b) Close up on a single body muscle cell (amplitude data shown), with clearly resolved sarcomere morphology. Note the resolution of single myosin filaments (white triangle) within the sarcomere. (c) Height data of a cross section through the mid-region of a C. elegans individual. (d) Height data of a close up on the vulva of a C. elegans individual. Scale bars (a) and (d) 4 µm, (b) 600 nm and (c) 8 µm; BM body muscle, Cut cuticle, I intestinal lumen, Mit mitochondrium, P pharynx, Sar sarcomere, V vulva, VM vulval muscle, YP yolk pool, white triangle single myosin filament.
