Stem cells and Covid-19

At least 14 trials using stem cells to treat coronavirus patients were reported in China. Animal

tests suggested stem cells might be able to repair the severe organ damage caused by Sars-

CoV-2. Moreover, MSCs have shown very significant immunomodulation. In particular, these

The clinical trial conducted in Beijing demonstrated that MSCs are naturally immune to Sars-
CoV-2. They secrete anti-inflammatory factors that seem to counteract the mechanisms at the
base of the virus-induced organ damage.

According to Beijing experts, MSCs would act by improving lung microenvironment, inhibiting
immune system overactivation, promoting tissue repair, protecting lung alveoli epithelial cells,
preventing pulmonary fibrosis, and improving lung function.

Mesenchymal stem cells are characterized by an enormous advantage. «They can be obtained
