title: Cell kinetic analysis in artificial skin using immunochemical methods.
abstract: Cell kinetic studies provide important information on histogenesis in vivo and in vitro. In this regard, specific antibodies to cell cycle-related antigens have been raised and characterized, thus permitting the study of cell kinetics using immunochemical methods. Recent advances in culture technology permitted the generation of human skin equivalents in vitro. We here provide detailed practical procedures for the study of epidermal cell kinetics in a model of artificial skin using immunohistochemistry and flow cytometry. The combined application of both techniques allows a precise detection of tissue growth sites and a quantitative assessment of cell growth. Moreover, simultaneous analysis of differentiation markers and proliferation antigens may be useful to understand molecular mechanisms that regulate tissue growth and development.
