The electron micrograph shows the tip of a primary cilium in a testis cell in primary culture. The plasma membrane of the adjacent cell has a coated pit juxtaposed to the ciliary tip.

We examined the structural organization of cytoskeletal components and membrane systems in neurons of well preserved biopsy material from Alzheimer’s disease (AD). Information was obtained from thin...

Alpha-synuclein aggregates in the dendrites of primary neurons expressing the reconstituted miniSOG-Jα. α-syn aggregates contained in membrane-limited organelles, fusing to the plasma membrane sugge...

Alpha-synuclein aggregates in the cell body of primary neurons expressing the reconstituted miniSOG-Jα.

Low magnification electron micrograph showing peroxisomes in several parenchymal cells in human liver, contrasted by catalase activity with DAB. A few organelles show a heterogeneous content: they are...

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...

Peroxisomes in human parenchymal liver cell, contrasted for catalase activity. Reaction product typically differs between individual organelles. Several mitochondria are seen, as well as many dark gl...

Peroxisomes proliferating under treatment with nafenopin over 17 days. Reaction product differs between adjacent organelles giving evidence that their content (catalase) is not freely exchanged, as pr...
