A view of the cortex showing early endosomes are often cup shaped and can have several coated evaginations arising from the rim of the cup. TEM taken on 8/10/65 by R. Allen with RCA EMU3F operating at...

High resolution image of vesicles and early endosomes under the membranelles of the peniculus of the buccal cavity. Cilia and basal bodies are tangentially fractured in this quick-freeze deep-etch pre...

Quick-freeze deep-etch rotary-shadowed replica of an early endosome with two clathrin-coated evaginations. Presumably these coated pits contain receptors for cargo that will be pinched off from the ea...

In some cells exposed to horseradish peroxidase (HRP) for 30 sec and then immediately fixed some HRP has already entered the cell by endocytosis and has been removed from the early endosomes in carrie...

Two parasomal sacs that are oriented perpendicular to the basal bodies. The top parasomal sac has a clathrin cage around it's coated pit area. The P-face of the plasma membrane has some IMPs, particul...

Transmission electron micrograph of Drosophila nephrocyte garland cell from ema[1] mutant: high magnification view. ema mutant garland cells are filled with very large electron-lucent alpha and electr...

Ema localizes to endosomes. Third instar larval garland cells expressing Ema-GFP fusion protein and stained for the early endosomal protein Rab5 (red) and plasma membrane and nuclei (blue). Ema does n...

An early endosome in planar view that contains HRP-reaction product. This cell was exposed to HRP for 6 min. and then fixed. This early endosome had two small coated evaginations arising from its rim ...

Vesicles and early endosomes under the membranelles of the peniculus of the buccal cavity. Cilia and basal bodies are tangentially fractured in this quick-freeze deep-etch preparation. Preendosomal ve...

Receptor mediated endocytosis is a process in which extracellular molecules are taken into the cell via coated vesicles that pinch from the plasma membrane. In Paramecium the resulting vesicles fuse w...
