Abstract

Claims (17)

1 . A method for treating acute respiratory distress syndrome (ARDS), the method comprising administering to a subject in need thereof a bone marrow mesenchymal stem cell (MSC) secretome composition comprising stem cell factor 1 (SCF1), ferritin protein, TIMP1 (tissue inhibitor of metalloproteinases 1), and IGFBP-4 (Insulin-like growth factor binding protein-4), wherein the treating comprises ameliorating fluid leakage in the lungs, improving oxygen uptake in the lungs, ameliorating lung damage, and/or ameliorating airway epithelial cell injury.

2 . The method of claim 1 , wherein the composition (i) increases interleukin-10 (IL-10) secretion by immune regulatory cells to inhibit hyperactive immune cell action; (ii) blocks plasmin production; (iii) suppress micro-blood clotting frequency; (iv) reduces thrombotic emboli; (v) inhibits a pathogen-induced cell death or NETosis; or (vi) any combination of two or more thereof.

3 . The method of claim 1 , wherein the composition increases (i) the level of total lymphocyte count by at least 20%; (ii) the level of one or more of CD3+ T lymphocytes, CD4+ T lymphocytes, CD8+ T lymphocytes, or combinations thereof by at least 25%; or (iii) both (i) and (ii).
