This is an important contribution, adding to the understanding of bone remodeling, which is not just relevant to arthritis but also to degenerative bone changes. Degenerative and inflammatory joint diseases lead to a destruction of the joint architecture. Whereas degenerative osteoarthritis results in the formation of new . Figure 3 New bone formation next to inflamed joints is increased upon blockade of DKK (a) Microphotographs of toluidine blue–stained joint sections of, ”from.

Integrins are cell surface adhesion receptors that link the cell surface to the extracellular matrix ECM or to other cells.

In addition, focal adhesion kinase FAK is an integrin-associated protein tyrosine kinase that enhances cell migration, proliferation and survival [ 19 ].
