IL10 and acute respiratory distress syndrome: In a model of Escherichia coli LPS-induced lung injury, MSCs activated with ARDS serum were more effective than naïve cells at increasing IL-10 levels (100-fold in plasma and twofold in bronchoalveolar lavage fluid (BALF)) and reducing inflammatory cell counts (≅15 × 104vs ≅60 × 104) and inflammatory cytokines in BALF, as well as lung inflammation score and vascular permeability (Table 1) [42].
