As previously described, the intermolecular interaction between the viral SP and human ACE2 Phase II CAStem cells will be intravenously injected into patients with or without acute respiratory distress syndrome (ARDS) induced by COVID-19. Phase II Patients with acute respiratory distress syndrome caused by COVID-19 will be treated with intravenous UC-MSCs at a dose 1 million xKg. Patient improvement will be evaluated over three weeks, along with the assessment of the immune profile, investigating the stem cells' effect on the cytokine storm. The similarities in systemic multi-organ complications between H7N9 and Sars-Cov-2 infections, along with direct evidence of the benefits of MSCs transplantation for COVID-19, further supports the potential of stem cells as an effective treatment [138] . ./cache/cord-268540-wrjzr3ws.txt ./txt/cord-268540-wrjzr3ws.txt
