Upper: capillary endothelial cell junction in the rete mirabile of the gas bladder of the toadfish Opsanus tau shows dense intracelluular plaques and the central dense line in the intercellular space,...

Human duodenal epithelium, at the level of the crypt. Fixation was carried out inbuffered formal-calcium. Peroxisomes are stained with DAB by their catalase activity at pH 10.5, postosmicated and embe...

Adult Caenorhabditis elegans (C. elegans) nematode imaged by DIC (differential interference contrast) microscopy. The angle of light allows for the visualization of many of the tissues in this living ...

Transmission electron micrograph of capillary rat intestine fenestrated endothelium. One of Dr. Palade's long standing interests concerned the structure and function of capillaries. He and his many co...

Transmission electron micrograph of mouse capillary intestine fenestrated endothelium with hemoglobin in the lumen lumen. The capillary lumen filled with hemoglobin shows continuities across endothe...

Early transmission electron micrograph of thin section of acinar cell on guinea pig pancreas. Rough endoplasmic reticulum, Golgi vesicles and portion of a zymogen granule are seen. Image made availab...

Nuclear pores are clearly seen in these transmission electron micrographs of cells after cryo-fixation, freeze-fracture and surface replication. Upper panel shows the outer surface of of the nuclear e...
