IL10 and allergic asthma: In the model of HDM-induced allergic asthma used herein, EPA-stimulated MSCs, compared to unstimulated MSCs, yielded greater therapeutic effects by further reducing bronchoconstriction, alveolar collapse, total cell count in BALF, bone marrow, and lymph nodes, and collagen fiber content in airways, while increasing BALF IL-10 levels and M2 macrophage counts in lungs.
