The aim of using information from data gathered in experimental animal models to improve our understanding of human disease requires some common reference points. For histological and cell biological analyses of tissues, such common reference points are only rarely established. The complex and highly polarized structure skeletal of muscle makes it an especially blatant example, where information must be interpreted with due caution when applied between species where differences in size, metabolism and lifestyle can have major influences. In this article it is proposed that data should be gathered in such a way as sy minimize minimize technical bias and to standardize, where possible, to reference denominators that common to the experimental system and to the system of basic interest, commonly Homo sapiens.
