abstract：:Recent evidence indicates that osteopontin (Opn), one of the bone matrix proteins, plays an important role in the attachment of osteoclasts to bone matrix. Besides being elaborated by osteoblasts, this protein is also produced by osteoclasts. The present study was performed to examine the effect of calcitonin (CT) on ...
