Mesenchymal Stem Cells: Case Report of an Adjuvant Ambulatory Therapy for a COVID-19 High-Risk and Steroid-hypersensitive Patients.

Introduction: Due to the rapid progression of COVID-19 to severe and critical stages, thousands of patients have required the use of intensive care unit (ICU) treatment, placing an excessive strain on health systems. Immunomodulatory effects of Wharton's Jelly Mesenchymal Stem Cells (WJ-MSCs) have shown promising results in the treatment of patients with COVID-19. However, the effect of promptly applied cell therapy on ambulatory patient prognosis has not been described.
