title: The study of epithelial function by quantitative light microscopy.
abstract: Quantitative light microscopy can be used to analyze the mechanisms of salt and water movement across epithelial cells. Methods for light microscopic visualization and image acquisition are reviewed. Video image recording and processing are shown to be essential for the study of epithelial cell function by light microscopy.
