Transmission electron micrograph of a pair of lipid droplets in the act of fusion or fission. This image was taken in a sertraline-treated swa2 mutant yeast cell. (25,000X). CIL 40426 shows more detai...

Transmission electron micrograph showing a vesicle fusing with a duct lumen in a rat pancreas. Image made available by James D. Jamieson and the Department of Cell Biology, Yale University School of ...

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...

Transmission electron micrograph of an unbudded yeast cell treaated with 60µM sertraline. The vacuolar contents are more electron-lucent, and vacuolar membrane is more discernible. A single lipid dro...

Quick-freeze deep-etch images show a more three dimensional view of acidosomes surrounding a phagosome. Acidosomes are unique in that they contain indentations of their membrane. The lumen has a honey...

The cytopharynx/nascent digestive vacuole (phagosome) has an E-fracture face containing a high number of IMPs. Interestingly these IMPs are sometimes organized into plaques where there are several sho...

Acidosomes originate from the biosynthetic pathway that includes the ER, the Golgi stack and the trans-Golgi network (TGN). Flattened vesicles from the TGN round up into spherical vesicles and bind to...
