Mechanisms for remodeling of connective tissue of the pelvic floor during pregnancy, childbirth and in the postpartum period

The analysis of literature data on molecular mechanisms for remodeling of connective tissue of the female reproductive system during pregnancy, childbirth and in the postpartum period is presented. The search for publications and their analysis was conducted in PUBMED, Google Scholar, eLIBRARY.RU databases. Particular attention was given to the study of expression pattern of specific proteinases involved in the process of synthesis and combination of elastic fibers, assembly of the collagen polypeptide chains at different stages. The place of matrix metalloproteinases and their tissue inhibitors in proteolytic degradation of the extracellular matrix of connective tissue is described. Pregnancy, childbirth and postpartum period are the triggering mechanism for connective tissue remodeling, certain mechanisms of which remain unclear and require further investigation.
