Webb1 maj 2014 · Bone-resorbing osteoclasts are polarized. In contact with bone, OCs exhibit functional membrane domains defining apico-basal polarity. At the bone surface level they form the actin-rich sealing zone (green) around integrins, such as αVβ3. Sealing zone delineates the ruffled border (RB) where bone degradation takes place. WebbOsteoclasts have the primary role in the process of bone repair and remodeling through the production of proteolytic enzymes, which leads to the resorption of bone matrix . The resorptive process utilizes the characteristic ruffled border feature of the osteoclast, thereby increasing the surface area available for ion exchange [ 37 ].

Webb1 jan. 2024 · Functioning osteoclasts form ruffled borders and clear zones. The clear zone is recognized as a thick band of actin, isolating resorption lacunae from the surroundings. The resorbing area under the ruffled border is acidic. Vacuolar proton ATPase (V-ATPase) exists in the ruffled border and lysosomal membranes. WebbThe ruffled border of an osteoclast is the folded membrane facing the side of the sealed zone. Since it faces the sealed zone, it plays a vital role in bone resorption. The ruffled border has a high concentration of vesicles, which help acidify and secrete enzymes into the microenvironment formed by the sealed zone.
