Collagen type I, III and V differently modulate synthesis and activation of matrix metalloproteinases by cultured rabbit periosteal fibroblasts.
In the present study we investigated whether the collagen types I, III and V affect the activity of fibroblasts obtained from rabbit periosteum. The cells were cultured on plates either or not coated with different amounts of collagen type I, III or V and analyzed for their attachment, DNA synthesis and the expression and activity of matrix metalloproteinases (MMPs). Our data show that the three collagen types promoted attachment and spreading of the cells and stimulated DNA synthesis when used in relatively low concentrations. High concentrations of type V-but not of type I or III-proved to inhibit thymidine incorporation. The expression and activity of matrix metalloproteinase 1 (MMP-1; interstitial collagenase) decreased under the influence of relatively low amounts of collagen (<40 microg/well), whereas higher levels increased its release. Matrix metalloproteinase 2 (MMP-2; gelatinase A) was up-regulated by the different types of collagen; the active fraction of stromelysin-1 (MMP-3) decreased. Accordingly, the mRNA expression of MMP-1 and -3 were reduced. The expression of MMP-2 mRNA, however, proved to be unaffected. Blocking antibodies to beta(1)-integrin or echistatin increased the level of MMP-1 but had no effect on MMP-2. All parameters tested were similarly affected by type I and III collagen, whereas the effect of type V was always less. We conclude that the collagen types I, III and V provide different sets of signals for fibroblasts that differently modulate their proliferation and MMP expression.
