Mesenchymal stem cells treatment in COVID-19 patient with multi-organ involvement.

The aim of this study is to evaluate the therapeutic effect of mesenchymal stem cells (MSCs) in a severe case of brain and multiple organ involvement in a patient with COVID-19. Here, a 51-year-old male patient with multi-organ involvement due to COVID-19 infection and developing cardiac arrest is presented. MSCs were transplanted to the patient four times systematically and once intrathecally. As a result, the application of MSCs has been found to have a healing effect on organs in this patient with severe COVID-19 infection. In addition, transplantation of MSCs both systematically and intrathecally is considered to be effective in the treatment of the central nervous system (Tab. 2, Fig. 2, Ref. 24).
