Abstract

Electron microscopy on the skin of young frogs, Rana temporaria, has been carried out with particular reference to cellular attachment sites. For the first time now several technical developments allow a more detailed visualization of the fine structure within the cellular attachment sites as well as making it possible to show the ultrastructural morphology of the junctional complexes, and to demonstrate that the desmosomes are regularly distributed around each skin cell, especially in the S. granulosum. The relations of these findings to those of previous investigations concerning the functional organization of the junctional complexes and to the findings in skin cancer from a cellular adhesion view point have been briefly discussed.
