In this volume the impact of cell culture models on dermatological research is discussed by scientists from medicine, physiology, biology, pharmacology, and pharmacy. The book includes the following topics: orthology and pathology of the skin, differentiation of keratinocytes and fibroblasts, problems of the cultivation of melanocytes, biochemistry of pigment metabolism, models for wound healing and tissue renewal, fibroblast function and metabolism of collagen, models for the investigation of ageing as well as models for pharmacological and toxicologial tests. Thus, a wide arch is spanned, from basic problems with cultivation and characterization of cell cultures to examples of application. Dermatologists as well as cell biologists will benefit from this publication.
