Studies suggest that the use of mesenchymal stem cells collected from umbilical cord blood and tissue are a safe and effective way to alleviate symptoms of coronavirus and promote fast recovery.

Recently, mesenchymal stem cells (MSCs) harvested from umbilical cord blood have attracted significant attention in clinical trials for COVID-19 due to their immunomodulatory and regenerative properties.

When an individual contracts COVID-19, an immune overreaction is triggered in the body, producing large amounts of inflammatory factors whilst simultaneously destroying numerous essential cells. This results in in an overproduction of immune cells and cytokines, which researchers refer to as an “inflammatory storm”.

Here, the idea to use MSCs in the treatment of COVID-19 patients was coined, to prevent the storm release of cytokines by the immune system and promote repair by reparative properties of the stem cells.

These MSCs oppose viral infections due to the presence of specific cytokines improved qualities. Subsequently, they can prevent lung tissue damage by counteracting the cytokine storm through their immunomodulatory function and differentiation ability to regenerate and reconstruct damaged tissue. As a result, it has been demonstrated that MSCs significantly reduce the risk of COVID-19 pneumonia and respiratory failure.

The application of these stem cells seems to be particularly effective in cases of critically ill patients, as reported in the Aging and Disease journal. In this study, seven COVID-19 patients were administered with MSCs from the umbilical cord. After two days of receiving the MSC treatment, the pulmonary function and symptoms of the seven patients were significantly improved without any adverse effects.
