The relationship between the actin cytoskeleton (blue), adherens junctions (green) and phospho-Myosin Light Chain (MLC) (red) after 30 minutes of calcium stimulation.

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...

Time series of meiosis I, starting at metaphase, in primary spermatocytes of the crane-fly Nephrotoma suturalis that have been experimentally flattened. Time-lapse polarization microscopy using a Nik...

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...
