Actin fiber organization in primary keratinocyte. There are numerous actin arcs around the periphery of the cell and actin bundles that terminate in focal adhesions (bright structures perpendicular t...

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 a rat diaphram capillary 24 hrs post intravenous administration of ferritin. Some ferritin is seen in the intracellular vesicles and extracellular spaces. Image m...

Human primary keratinocyte spreading on an asymmetric "arc"-shaped collagen I micropattern. The cells are stained for the focal adhesion protein vinculin (green, Alexa488), F-Actin (red, TRITC phallo...

Transmission electron micrographs of Opossum spermatogonia showing different regions within the nucleolus. One region is more lightly staining and fine textured, the other denser and more coarsely tex...

The midpiece of spermatzoa in nearly all vertebrates is enclosed in a sheath of mitochondria, which provide a ready source of ATP necessary for sperm motility. Here, a longitudinal section through sp...

Figures 206 (upper) and 207 (lower) from Chapter 6 (Golgi Apparatus) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. During development of the acrosome in the chinchilla spermatid, the transitional zon...
