Abstract
By using confocal laser scanning microscopy (CLSM), intracellular and intratumoral fluorescence localization of several promising photosensitizing fluorophores, such as the derivatives of sulfonated aluminum phthalocyanines (AlPCSn, n equals 1-4), meso- tetra(hydroxyphenyl)porphine (m-THPP) and its chlorin (m-THPC) was studied in several cancer cell lines in vitro and in tumor models in vivo. The correlation of the subcellular and intratumoral localization patterns of the potent photosensitizers with the targets of photodynamic action is discussed. Also, the advantages of using CLSM for studying the fluorescence properties of the photosensitizing fluorochromes in a biological system is emphasized.
