Human uterine cervical tissue is composed mainly of fibroblast cells and the extracellular matrix in which collagen types I and III predominate. It is hypothesized that these collagens are degraded by matrix metalloproteinases (MMPs) in the initial step of uterine cervical ripening during parturition. Among the MMPs, MMP-1, -8 and -13 have substrate selectivity for collagen types I and III. In the present study, we examined the regulation of MMP-1 secretion from the human uterine cervix. Immunohistochemistry detected strong staining of MMP-1, but not of MMP-8 or -13, in stromal cells of the pregnant uterine cervix. The MMP-1 expression in the pregnant uterine cervix was further confirmed by Western blot analysis and RTPCR. To clarify the regulation of MMP-1 production, we subsequently investigated the effects of prostaglandins, inflammatory cytokines and cyclic mechanical stretch on the secretion of MMP-1 from cultured human uterine cervical fibroblast cells. Treatment with prostaglandin (PG)F2
(10-7 to 10-5 mol/l) or interleukin (IL)-1
(0.011.0 ng/ml) or stimulation with cyclic mechanical stretch increased MMP-1 secretion from cultured human uterine cervical fibroblast cells, with maximal increases of 3.4-, 4.5- and 1.9-fold respectively (24 h of treatment, P < 0.05 for all comparisons). These data suggest that MMP-1 may play a significant role in the degradation of extracellular collagen types I and III in the pregnant uterine cervix during the process of cervical ripening, in response to various stimulations such as PGF2
, IL-1
and mechanical stretch.
