“…Osteoclast-mediated resorption of bone takes place in Howship's lacunae where the osteoclasts are attached to components of the bone matrix such as osteopontin (Bringhurst et al 2005). The active osteoclast surface contains a specialized proton-pump ATPase, which secretes acid and solubilizes the mineral phase (Baron 2001). The bone matrix is resorbed in the acid environment adjacent to the border by proteases that act at low pH, such as cathepsin K.…”

“…Le remodelage osseux est assuré par deux types de cellules, les ostéoclastes et les ostéoblastes. Les ostéoclastes sont des cellules différenciées issues de précurseurs hématopoïétiques, qui adhèrent à la surface de la matrice osseuse et résorbent l'os minéralisé par des mécanismes enzymatiques complexes [9]. Les ostéoblastes sont issus de la différen-ciation de cellules souches du stroma médullaire, et synthétisent les protéines qui vont constituer la matrice osseuse [10].…”

“…The presence of an acidic pH within the resorption gap enclosed between the active osteoclast and the bone matrix is the major barrier to the direct action of these endopeptidases during the resorption phase. The role of MMPs is thus centered on the adhesion and migration of osteoclasts during bone remodeling (13).…”
