title: Ultrastructural morphometry of isolated cells: methods, models and applications.
abstract: Isolated cells constitute a favourable experimental model for the pathologist interested in ultrastructural morphometry. A particular advantage is that the same sampling regime may be appropriate for both normal and pathologically-altered material. Often this is not the case with other model systems. This report reviews alternative methodologies for analysing isolated cells, including free cells and dissociated cells in culture. We begin by attempting to define problems of more general concern: preparative techniques, methods of sampling, selection of stereological parameters and possible sources of error. A generalised morphometric model for isolated cells is followed by descriptions of models devised for specific cell types, notably mononuclear phagocytes and cells of the lymphocyte family. Typical results obtained by stereological analyses of these models are presented.
