Interventions using placenta-derived mesenchymal stem cells (pMSCs, 26), human fetal lung-derived mesenchymal stem cells (hFL-MSCs, 27), or carnitine palmitoyltransferase 1 (CPT1A, 28) have all found that the suppression of the ALI inflammatory response is IL-10-mediated, and blocking the IL-10 signaling pathway exacerbates the inflammatory response in ALI (29). Here, IL10 is linked to acute respiratory distress syndrome.
