Exosomes are nanoparticles, sized 30-100 nm, produced by the reverse budding of multivesicular bodies
upon fusion with plasma membranes.
The vacuole formation can be related to the tonoplast disruption, forming vesicles and multivesicular bodies
(Wei & Miller, 1972).
The basal cytoplasm displays dense tubular elements, coated vesicles, multivesicular bodies
, and lysosomes.
Exosomes are small (30-100 nm) membrane vesicles released into the extracellular environment on fusion of multivesicular bodies
with the plasma membrane .
Exosomes are 30 to 100 nm extracellular membrane vesicles of endocytic origin, which are released into the extracellular environment upon fusion of multivesicular bodies
with the plasma membrane.
They also are distinguished based on biogenesis pathway; MV from the plasma membrane and EXO originate from within multivesicular bodies
(MVB) and are secreted by fusion of MVB with the plasma membrane (RAPOSO & STOORVOGEL, 2013).
They are formed from multivesicular bodies
(MVBs), which are intracellular endosomal organelles, characterized by multiple intraluminal vesicles enclosed within a single outer membrane.
This explains the many autophagic vacuoles, lysosomes, and multivesicular bodies
near the intracellular canal.
The supranuclear cytoplasm of the principal cells in the lining epithelium of Agouti paca vas deferens showed at ultrastructural level a well-developed endocytotic apparatus characterized by presence of a large number of lysosomes disposed adjacent to multivesicular bodies
with pale or denser content, and by occurrence of endosomes.
Cells with absorptive function that is rarely observed in the epithelial layer have microvilli on the free surface; and several pinocytotic vesicles, multivesicular bodies
, and mitochondria were found in the upper portion of cytoplasm (Fig.
Coronavirus particles may be confused morphologically with other nonviral structures routinely found in cells, including coated vesicles, multivesicular bodies
, perichromatin granules, glycocalyceal bodies, and cellular projections (see 29).
Light and dense multivesicular bodies
, as well as hybrid cells containing both multiple vesicles and autophagic material, have also been identified.
