Beyond their well described immune modulating effects, where inflammation can be resolved in many organs, and specifically addressing acute respiratory distress syndrome (ARDS), the total collection of molecules released from MSCs can reduce lung inflammation, as well as restore alveolar fluid clearance, and exert antimicrobial activity party through keratinocyte growth factor (KGF) secretion [45,46]. This evidence concerns the gene FGF7 and acute respiratory distress syndrome.
