Fig. 3From: Potential therapeutic application of mesenchymal stem cell-derived exosomes in SARS-CoV-2 pneumoniaPossible mechanisms, by which mesenchymal stem cell-derived exosomes may improve adverse effects of SARS-CoV-2 virus infection. These exosomes contain different molecules that can suppress inflammatory responses and repair damage tissue.
