This paper presents the ultramicroscopic structure of the epidermis in senile elastosis, and compares it with the structure of an induced regenerated specimen in the same layers. In the regenerated specimen it was found that tonofilament-desmosome complexes have been replaced by a regular twist of villous processes. Such a substitution influences the structure and function of keratinocytes. Newly-formed structures may be established even 10 years after the induction.
