Clinical Research of Human Mesenchymal Stem Cells in the Treatment of COVID-19 Pneumonia

The COVID-19 pneumonia has grown to be a global public health emergency since patients were first detected in Wuhan, China, in December 2019, which spread quickly to worldwide and presented a serious threat to public health. It is mainly characterized by fever, dry cough, shortness of breath and breathing difficulties. Some patients may develop into rapid and deadly respiratory system injury with overwhelming inflammation in the lung. Currently, no specific drugs or vaccines are available to cure the patients with COVID-19 pneumonia. Hence, there is a large unmet need for a safe and effective treatment for COVID-19 pneumonia patients, especially the critically ill cases. The significant clinical outcome and well tolerance was observed by the adoptive transfer of allogenic MSCs. We proposed that the adoptive transfer therapy of MSCs might be an ideal choice to be used. We expect to provide new options for the treatment of critically ill COVID-19 pneumonia patients and contribute to improving the quality of life of critically ill patients.
