Uptake of yolk protein into coated vesicles (arrows) at the periphery of oocytes of the cockroach Periplaneta americana. Yolk protein binds to regions of the membrane with a prominent glycocalyx. Beca...

This transmission electron micrograph of a section through a late orthochromatic erythroblast (normoblast) from human bone marrow shows shallow depressions along the membrane surface, indicated by arr...

Stages of coated pit vesicle invagination during micropinocytosis. Each frame is a portion of the surface of polychromatophilic erythroblasts from guinea pig bone marrow and various stages of vesicle...

Transmission electron micrograph of coated vesicles in mouse cardiac tissue. Coated vesicles have the materials bound to the receptor molecules incorporated within their membranes allowing the vesicl...

A high resolution image of a cell actively undergoing endocytosis that develops an extensive layer of vesicles and cisternae composed for the most part of smooth undecorated membrane. The uncoated cis...

Dictyosomal elements of the Golgi complex consist of a layer of coated transition vesicles next to a specialized area of ER called the transition zone and two or three highly fenestrated layers of cis...

The Golgi stack is comprised of seven cisternae, but only the seventh (trans-most) cisterna displays clathrin coated budding profiles. Clathrin spikes are clearly seen on equatorial views of certain b...

Early transmission electron micrograph of a thin section of a secretory cell from guinea pig pancreas illustrating vesicle trafficking between the rough endoplasmic reticulum and Golgi apparatus (uppe...

Movie Focusing on the model of the two trans-most cisternae, C6 and C7. The penultimate trans-cisterna (C6-gold) is a tubular reticular cisterna, that extends tubules trans of the trans-most cisterna ...

Cultured retinal pigment epithelial cells immunofluorescently labeled for adaptor protein-2 (AP2) (green) and nucleus (blue). The cells were fixed in 2% PFA and 0.5% Triton X-100 for 2 minutes follow...
