Abstract: | The study of energy pools and dynamics of specific pathways in living cells by microspectrofluorometry and fluorescence imaging produces spectral and topographic images characterizing structural and functional changes associated with cytopathology. Microspectro-fluorometry and fluorescence imaging have been applied, together with organelle morphometry to a number of cells mimicking certain cytopathologies, including melanoma cells, long-term malignant cells, and gene-defective cells. These investigations of cellular pathology indicate that there is a convergence of various physiopathological processes. Cellular states that have similarities include senescence, detoxification, and transformation. While the NAD(P)H metabolic transients have been studied before, our emphasis in this article is on very rapidly scanned fluorescence images related to organelle integration and photoinduced cellular senescence. |
