Description

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 cisternae are early endosomes to which uncoated vesicles that first arise as coated vesicles from the parasomal sacs fuse with the cisternae to deposit their load of receptor-mediated cargo. Smaller clathrin-coated vesicles bud from the early endosomes and these are either recycled back to the plasma membrane or move deeper into the cell as carrier vesicles after they lose their clathrin coats. TEM taken on 5/21/79 by R. Allen with Hitachi HU11A operating at 75kV. Neg. 26,250X. The raw film was scanned with a Epson Perfection V750 Pro. This image is best used for quantitative analysis. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness.
