The arrangement of collagen fibers has previously been studied with picrosirius red (PSR) staining and brightfield microscopy. We discovered that PSR staining can also be visualized by fluorescence microscopy. PSR-stained collagen was strongly fluorescent using excitation and barrier filters for rhodamine, and distracting background cytoplasmic fluorescence was drastically reduced with phosphomolybdic acid (PMA) treatment before PSR staining. The PMA-PSR fluorescence method was more sensitive than the brightfield PSR or PMA-PSR method, and permitted confocal microscopic study. We applied the method to the study of collagen fiber three-dimensional arrangement in perimysial and endomysial septa of the heart, showing the three-dimensional course of the fibers in stereo views generated by confocal microscopy. The PMA-PSR fluorescence method should be generally useful for accurately determining collagen fiber three-dimensional arrangement, a necessary prelude to mechanical modeling of collagen-reinforced tissues.
