Can we use Mesenchymal Stem Cell transplantation for COVID-19 patients in puerperium period?

To the Editor, The Coronavirus disease-2019 (COVID-19) pandemic has affected the whole world, and pregnant women and women in the postpartum period have not been spared from its effects. Pregnant women during this pandemic pose an unknown risk to their babies. We followed up pregnant and post-pregnancy COVID-19 patients in this period in the intensive care unit (ICU) and used mesenchymal stem cell (MSCs) transplantation in suitable patients. We aimed to investigate patients with COVID-19 pneumonia and who were hospitalized in the ICU after C-section in the puerperium period and either given or not given MSCs treatment.
