Ex vivo stimulation of MSCs with serum led to further improvement in lung mechanics in vivo. Static lung elastance (Est,L; upper panel), resistive (ΔP1,L), and viscoelastic (ΔP2,L) pressures (lower panel). CTRL, phosphate‐buffered saline‐challenged mice; HDM, HDM‐challenged mice; SAL, HDM mice treated with saline; MSC, HDM mice treated with unstimulated MSCs; HDM‐MSC‐BALF, HDM mice treated with MSCs stimulated with BALF from asthmatic mice; HDM‐MSC‐SERUM, HDM mice treated with MSCs stimulated with serum from asthmatic mice. Bars represent mean ± SD of eight animals per group. *, Significantly different from CTRL (p < .05). **, Significantly different from HDM‐SAL (p < .05). #, Significantly different from HDM‐MSC (p < .05). Abbreviations: BALF, bronchoalveolar lavage fluid; MSC, mesenchymal stromal cells; HDM, house dust mite.
