Fluorescence microscopy, uniquely, provides the ability to examine specific components within intact, even living, cells. Unfortunately, high-resolution conventional fluorescence microscopy is intrinsically a two-dimensional technique and performs poorly with specimens thicker than about 0.5 micron. Probing the spatial organization of components within cells has required the development of new methods optimized for three-dimensional data collection, processing, display, and interpretation. Our interest in understanding the relationship between chromosome structure and function has led us to develop the necessary methodology for exploring cell structures in three dimensions. It is now possible to determine directly the three-dimensional spatial organization of diploid chromosomes within intact nuclei throughout most of the mitotic the cell cycle.
