To this end, rats with VILI were randomly distributed into 3 treatment groups (<span class="elsevierStyleItalic">N</span><span class="elsevierStyleHsp" style=""></span>=<span class="elsevierStyleHsp" style=""></span>8 each): vehicle, non-preconditioned MSCs and preconditioned MSCs (4<span class="elsevierStyleHsp" style=""></span>×<span class="elsevierStyleHsp" style=""></span>10<span class="elsevierStyleSup">6</span><span class="elsevierStyleHsp" style=""></span>cells/kg in 500<span class="elsevierStyleHsp" style=""></span>μL, in both cases). After treatment, the rats were kept under baseline ventilation for 4<span class="elsevierStyleHsp" style=""></span>h and then (end-point) elastance was measured, bronchoalveolar lavage fluid (BALF) was obtained from one lung for measuring total cell, neutrophil, protein and inflammatory cytokines (TNF-α and CXCL2) concentrations, and the other lung was excised for assessing oedema by its weight/dry ratio.<a class="elsevierStyleCrossRef" href="#bib0150"><span class="elsevierStyleSup">15</span></a> A group of control rats (<span class="elsevierStyleItalic">N</span><span class="elsevierStyleHsp" style=""></span>=<span class="elsevierStyleHsp" style=""></span>8) was maintained under initial ventilation (no VILI, no treatment) for the same total time. MSCs engraftment in the lungs was assessed in additional VILI rats treated with fluorescently (PKH26) stained MSCs with/out (<span class="elsevierStyleItalic">N</span><span class="elsevierStyleHsp" style=""></span>=<span class="elsevierStyleHsp" style=""></span>6 each) preconditioning.</p><p id="par0025" class="elsevierStylePara elsevierViewall">After a ∼20% increase in elastance, established by protocol, only preconditioned MSCs induced a significant recovery in elastance (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>A; paired <span class="elsevierStyleItalic">t</span>-test). In VILI, lung oedema increased by 16% and all the other 6 outcome variables augmented by more than 2-fold (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>B), reflecting typical increase in alveolar-capillary membrane permeability and inflammation. The statistical significance of the overall effect of VILI treatment with MSCs was assessed by conducting a rank-ANOVA to the sum of the 6 outcome variables after applying a normal standardization (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>B). The novel and relevant result of this study, which confirms our hypothesis, was that biophysically preconditioned MSCs were more effective than non-preconditioned MSCs in reducing VILI. In fact, while the effect of non-preconditioned MSCs was low, preconditioned MSCs achieved a significant recovery from VILI (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>B).

Notwithstanding, this work opens a considerable number of important questions. Among the more specific, whether the positive effects of biophysically preconditioned MSCs we observed would be reproduced in a more severe and long-term VILI model. More general questions include the comparison of the effects of preconditioning lung-derived <span class="elsevierStyleItalic">vs</span> bone marrow-derived MSCs, or application of MSCs <span class="elsevierStyleItalic">vs</span> their supernatant, extracellular vesicles or mRNAs. It would also be important to test the effects of biophysically preconditioned MSCs on other experimental one-hit or two-hit models of intra- and extra-pulmonary ARDS (<span class="elsevierStyleItalic">e.g.</span> induced by LPS, bacterial lung infection, acid lavage, intra-abdominal or systemic sepsis).</p><p id="par0035" class="elsevierStylePara elsevierViewall">In conclusion, we believe that this study opens an avenue for future research aimed at understanding the basic repair mechanisms activated in MSCs by physiomimetic stimuli, with the translational perspective towards the use of these cells as a tool to improve the treatment of lung injury.</p><span id="sec0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0005">Funding</span><p id="par0040" class="elsevierStylePara elsevierViewall">This work was supported in part by the <span class="elsevierStyleGrantSponsor" id="gs1">Spanish Ministry of Economy and Competitiveness</span> (<span class="elsevierStyleGrantNumber" refid="gs1">SAF2017-85574-R</span>, <span class="elsevierStyleGrantNumber" refid="gs1">DPI2017-83721-P</span>) and <span class="elsevierStyleGrantSponsor" id="gs2">Generalitat de Catalunya (Programa CERCA)</span>.
