Scanning electron micrograph showing in vitro fertilization of a hamster oocyte. The sperm head, near the center of the field of view, is engulfed by the microvilli on the surface of the oocyte membr...

Scanning electron micrograph showing a lateral view of sperm penetration of a hamster oocyte during vitro fertilization. As the membrane of the sperm head fuses with that of the oocyte, the microvill...

Scanning electron micrograph montage of cultured HeLa cells. This image is a montage of six overlapping fields of view, each photographed at 2,231x with a 17.8mm working distance and an accelerating v...

Chick Chorioallantoic Membrane (CAM). This scanning electron micrograph shows a section through part of a chick chorioallantoic membrane. A blood vessel has been fractured in the middle of CAM reveal...

Surface of the zona pellucida surrounding a hamster oocyte. This scanning electron micrograph shows the zona pellicida around a hamster oocyte at high magnification. The zona pellicida has a complex ...

An REF-52 cytoskeleton with actin filaments decorated by myosin S1. An intermediate filament associates with an actin filament bundle via plectin sidearms (10-nm immunogold labeling). Electron micros...

Association of plectin with myosin II. A gelsolin-treated REF-52 cell immunogold labeled for plectin (10 nm). After actin depletion, intermediate filaments with plectin sidearms bind to clusters of my...

Plectin sidearms and intermediate filaments labeled with plectin immuno-gold (10 nm) in control cells. Cells with a similar label, but with actin removed by gelsolin treatment appears as CIL: 23403. ...
