The Placental Secretome as a Therapeutic Tool to Prevent Inflammation-induced Preterm Birth

Sponsor: Fondazione Policlinico Universitario Agostino Gemelli IRCCS

Summary

Preterm birth complicates 10% of all pregnancies and is the leading cause of perinatal morbidity and mortality worldwide. Intra-amniotic inflammation (IAI) and chorioamnionitis are well-established causes of PTB; however, a treatable infectious trigger is identified in only 50% of cases.In sterile IAI and/or preterm premature rupture of membranes (pPROM), there are currently no effective therapeutic options to reduce inflammation, promote amniotic sac healing, and prevent preterm birth. Growing evidence suggests that the secretome of mesenchymal stem cells (MSC) exhibits immunomodulatory and tissue-regenerative properties, making it a promising therapeutic tool for inflammatory disorders. Specifically, the conditioned medium from human amniotic mesenchymal stromal cells (CM-hAMSC) has been successfully used to treat various preclinical inflammatory disease models. The aims of this study will be:1) to evaluate the activation of the NLRP3 inflammasome in hAM cells and peripheral blood mononuclear cells (PBMCs) from women with PTB. 2)To investigate the effect of CM-hAMSC on NLRP3 activation induced by lipopolysaccharide (LPS) and nigericin in cultured human amniotic epithelial cells (hAECs), amniotic mesenchymal stromal cells (hAMSCs), and PBMCs.
