Matrix metallopeptidase 9, also known as MMP9, is a biological enzyme that is a member of the matrix metalloproteinases (MMPs). MMP9 is thought to play a critical role in tumor cell invasion,1 breakdown of extracellular matrix in normal physiological processes, such as embryonic development, reproduction, and tissue remodeling, as well as in disease processes, such as arthritis and metastasis. MMP-9 is secreted from cells and, once activated, is thought to degrade collagen in the extracellular matrix.2 MMP-9 is one of the major proteases produced by osteoclasts and possibly plays a role in osteoclastic bone resorption.3
