IL1B and acute respiratory distress syndrome: 2015), we performed an unbiased, genome‐wide exploratory analysis of human ATII cell gene expression in response to stimulation with proinflammatory cytokines in the presence or absence of MSCs. We first examined the gene expression of ATII cells exposed to CytoMix (a mixture of TNF‐α, IL‐1β, and IFN‐γ), which models the proinflammatory edema fluid of ARDS (Lee et al. 2007).
