These results add to the developing number of observations that conditioned media and, in unique, EVs released by the MSCs can convey numerous of your protective actions of the MSCs. MSC-secreted EVs have already been shown to have anti-inflammatory effects in extra than one model of lung disease, in spite of the fact that the underlying inflammation is various amongst the models. It seems, therefore, that their major immunomodulatory action may possibly be among restoration of a balance perturbed by diseaserather than the suppression of a precise type of inflammation. Importantly, our results also demonstrate efficient xenogeneic actions of human MSC-derived conditioned media and EVs in an immunocompetent model of lung illness, and present further impetus for employing immunocompetent mouse models to investigate mechanisms of MSC actions.ACKNOWLEDGMENTSWe thank Nirav Daphtary and Minara Aliyeva on the Vermont Lung Center Core facility for help with Flexivent technical help; Joseph Platz, Vikas Anathy, and Matthew Poynter, for S TEM C ELLS T RANSLATIONAL M EDICINE�AlphaMed PressCruz, Borg, Goodwin et al.constructive suggestions; and Michele von Turkovich with the UVM Imaging Facility for assistance using the TEM pictures.
