Bone matrix function
WebThe loss of MMP-13, and the resulting defects in perilacunar remodeling and matrix organization, compromise MMP-13(-/-) bone fracture toughness and postyield behavior. Taken together, these findings demonstrate that osteocyte perilacunar remodeling of mid-cortical bone matrix requires MMP-13 and is essential for the maintenance of bone quality.

WebBone is a unique tissue composed of numerous cell types entombed within a mineralized matrix each with its own unique functions. While the majority of the matrix is composed of inorganic materials, study of the organic components has yielded most of the insights into the roles and regulation of cell and tissue specific functions. WebBone matrix. Bone matrix is a composite material that derives its strength from a compression-resistant mineral phase and a tension-resistant network of collagen fibers. Bone's mineral phase – calcium hydroxyapatite, Ca 10 (PO 4) 6 (OH) 2 – is subdivided into a mosaic of tiny microcrystallites, thereby creating a large surface area for ion exchange …
