摘要: The lactating mammary gland is one of the most highly differentiated and metabolically active organs in body. Membranes cell have important roles transmitting from membrane to another hormonal information milk secretion, which final event. During projection surface into alveolar lumen by enveloping intracellular lipid droplets with apical plasma remarkable aspects biological action throughout nature. This review focuses on current knowledge about membranes gland. (1) Advances isolation properties membranes, especially Golgi-derived secretory vesicles, concerned secretion are described. (2) Milk serum components secreted fusing vesicles that condense secretions regions. occurs through formation a tubular-shaped vesicular depression ball-and-socket configuration, as well simple fusion. (3) Intracellular directly extruded epithelial cells progressive envelopment (4) balance between volume lost provided fusion vesicle other discussed. (5) surrounding fat globule, referred globule (MFGM), composed at least coating an droplet, membrane, coat material. Consequently, MFGM molecularly different composition. (6) bovine structurally inner outer just after segregation. These two fused reorganized process vesiculation fragmentation stabilize globules. Hypothetical structural models for globules rearrangement proposed.
