Multivesicular Bodies

Multivesicular bodies ( MVBs) 1 in a canine epithelial cell (liver), which are locate d in the cytosol, close to the apical cell border. Multivesicular bodies are vacuoles with a surrounding membrane and a variable number of enclosed small vesicles. They are part of the group of secondary lysosomes and contain acid phosphatase, among other components. MVBs probably play a role in crinophagy, meaning that they help recapture an excess of secretory products in the cells of endocrine and exocrine glands.
