Gap junctions in ciliary epithelium under conditions of oxygenation (upper) and anoxia (lower), in tissue prepared by ultrarapid freezing using liquid helium. Under oxygenated conditions, the connexo...

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,...

Exposure of a cortical neuron to netrin induces the phosphorylation of focal adhesion kinase (FAK) at Tyr397 along the axon and within the growth cone (gc). Insert shows the control neuron (without tr...

High resolution view of early endosomes with coated evaginations at their margins.TEM taken on 8/15/67 by R. Allen with Philips 200 operating at 60kV. Neg. 19,200X. The raw film was scanned with an E...

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...

6 MIIB inhibits adhesion turnover. Time-lapse of a CHO.K1 cell cotransfected with very low levels of GFP-MIIB (myosin IIB, green) and paxillin (magenta). Note that adhesions adjacent to MIIB-containin...

Transmission electron micrograph of a tight junction (zonula occludens)between two cells in a section of tissue from a rat thyroid. Image made available by James D. Jamieson and the Department of Cel...

Maximum intensity projection of Golgi impregnated pyramidal neurons in the neocortex of an adult mouse, imaged via serial block-face scanning electron microscopy. Contrast is reversed so that Golgi s...

This figure shows the connection between the peristome and the food vacuole forming zone where the alveoli end. The cytostome is the opening that connects these two zones. TEM taken on 6/13/69 by R. ...

Tetrahymena cells that are not forming a digestive vacuole often have a tube-like extension of the cytopharyngeal membrane attached to the deep fiber that extends several microns into the cytoplasm. T...
