High resolution scanning force microscopy of cardiac myocytes.
The advent of scanning probe microscopy has introduced a powerful new method of probing the structural features of biological specimens. In this study, high resolution atomic force microscopy micrographs of single, isolated, cardiac myocytes are presented. Significantly, our images show not only the features to be expected of the external sarcolemma, but also resolve sub-surface features, including the striated pattern of the contractile proteins and their associated sarcoplasmic reticulum and mitochondria.
