Dear Editor,
Stem cell therapy has been investigated by a number of basic, pre-clinical and clinical studies, and these studies have proved that stem cells are safe and effective in the treatment of many medical conditions and diseases.(11. Alessandrini M, Preynat-Seauve O, De Bruin K, Pepper MS. Stem cell therapy for neurological disorders. S Afr Med J. 2019;109(8b):70-7. Review.

A study including 10 patients with confirmed diagnosis for coronavirus 2019 (COVID-19), and pneumonia due to infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), reported significant improvement in symptoms of all patients treated with mesenchymal stem cells (MSCs) with no adverse effects. Of these patients, 7 were treated with intravenous concentration of 1x106 cells per kilogram of body weight and 3 were treated with placebo. Patients were followed-up for 14 days. Results observed included a significant reduction of chest infiltration, reduction of proinflammatory cytocines including tumor necrosis factor alpha (TNF-α), and an increase of peripheral lymphocytes rate with phenotype recovering of CD4+ T cell count and dendritic. In addition, an increase was observed of anti-inflammatory gene expression and trophic factors.(55. Leng Z, Zhu R, Hou W, Feng Y, Yang Y, Han Q, et al. Transplantation of ACE2(-)mesenchymal stem cells improves the outcome of patients with COVID-19 pneumonia. Aging Dis. 2020;11(2):216-28.) Although further studies including more patients are warranted, data published in the literature so far suggest that MSCs is safe and effective for treatment in patients with SARS-CoV-2 pneumonia.(55. Leng Z, Zhu R, Hou W, Feng Y, Yang Y, Han Q, et al. Transplantation of ACE2(-)mesenchymal stem cells improves the outcome of patients with COVID-19 pneumonia. Aging Dis. 2020;11(2):216-28.)
