To examine the role of matrix metalloproteinases(MMP) expressed by the tartrate-resistant acid phosphatase (TRAP)-positive mononuclear and multinucleated cells in articular cartilage damage.
[Expression of MMP-2 and MMP-9 in the tartrate-resistant acid phosphatase (TRAP)-positive mononuclear and multinucleated cells is correlated with articular cartilage damage].
