early endosomes

early endosomes

membrane-bound compartments located near the cell membrane with an internal pH of 6.0. Pinocytotic vesicles fuse with early endosomes and, frequently, receptors and ligands are uncoupled here. Receptors are returned to the cell membrane and ligands or other material delivered by pinocytotic vesicles are transferred to late endosomes.
See also: compartment for uncoupling receptors and ligands.

The formation of early endosomes and MVBs has been shown to increase upon signaling via growth factor receptors, suggesting that the cell adjusts exosome production according to its need (12,20).
