Several previous studies indicated that MSCs could enhance the resolution of inflammation in adult ALI patients [16, 35], and sufficient evidence also showed the same modulatory effect: Proinflammatory cytokines such as interferon-γ, IL-1β, and IL-6 were reduced, while the anti-inflammatory cytokines IL-4 and IL-10 were increased [38]. This evidence concerns the gene IL6 and acute respiratory distress syndrome.
