Matrix metalloproteinase-9 and tissue inhibitor of metalloproteinase-1 in plasma/serum and urine of women during term and threatened preterm labor: a clinical approach

Abstract

Alterations in the concentrations of proMMP-9 and TIMP-1 can be detected in plasma or serum and urine of pregnant women experiencing term or preterm uterine contractions. The altered values of proMMP-9 and TIMP-1 could possibly identify the inevitable progress of preterm contractions to true preterm labor.
