OBJECTIVES: To assess the level MMP-9, TIMP-1 and TGF-β in placental and cervical region of amniotic membranes derived from at-term, pre-term and PROM deliveries.
MATERIAL AND METHODS: 14 amniotic membranes have been assessed; the quantitative analysis of MMP-9, TGF-β and TIMP-1 was assayed using respective Quantikine Immunoassay Kit.
RESULTS: The MMP-9 level in PROM samples was similar to the level of MMP-9 in at-term membranes and comparable between the cervical and placental region of these membranes. The concentration of TGF-β and TIMP-1 was decreased in the cervical area of AM derived from deliveries complicated with PROM.
CONCLUSION: The MMP9/TIMP-1 imbalance, as well as the reduced level of TGF-β may be possible risk factors of pre-term labor and PROM.
