Next, we describe some of the most significant clinical evidence of the successful use of MSC-derived exosomes in animal models of lung and heart injuries, which might strengthen our hypothesis in terms of their utility for also treating critically ill COVID-19 patients. Recently, MSC-derived exosomes have been demonstrated to have comparable and even greater effects than cells themselves in improving inflammation and injury in a variety of pre-clinical lung disease models, including ALI/ARDS (Table 1) . From the studies discussed above, it emerged that the rationale for using MSC-derived exosomes, MVs, or EVs in ALI/ARDS is based on several processes, many of which are shared with those identified in the parent MSCs. These include immunomodulation and anti-inflammatory properties on host tissue, reduction of the permeability of alveolar epithelium and endothelium, improvement of alveolar fluid clearance, enhancement of macrophage phagocytosis, and tissue repair through direct mitochondrial transfer with host cells (Figure 2 ). ./cache/cord-333520-v2sb90rc.txt ./txt/cord-333520-v2sb90rc.txt
