Normal morphology of two peroxisomes (marked P) in a human liver parenchymal cell. They are contiguous with a narrow endoplasmic reticulum cisterna; this relationship is frequent. The image also shows...

Human duodenal epithelium. Peroxisomes are stained with DAB at pH 10.5 by their catalase activity and postosmicated. 0.5 µm plastic section were visualized using electron microscopy at low magnificat...

Image of normal human iiver parenchymal cells, where peroxisomes are stained brown with DAB by their catalase activity at pH 10.5. No counterstain was used. Prefixation was carried out in buffered for...

Representative time-lapse movie of a human mammary tumor fragment in Matrigel. CIL 42161 is a related movie that shows a human mammary tumor fragment in collagen. Images collected every 20 minutes a...

Representative time-lapse movie of a human mammary tumor fragment in collagen. CIL 42160 is a movie of a normal mammary fragment in Matrigel. Images collected every 20 minutes and bar is 50 microns....
