Thin section electron microscopy of diaphragm (skeletal) muscle from a wild type mouse. Sample was viewed with a Hitachi 7600 electron microscope (accelerating voltage 80 KV) and imaged with an AMT digital camera. Image taken at 30,000X magnification. This image is part of a set of wild type diaphragm muscle images that served as controls for the study of the delta-sarcoglycan knockout mouse. Both the set of wild-type and delta-sarcoglycan knockout mouse images are part of The CELL: an image library. Reference: Nat Med. 2008 Apr;14(4):442-7.
