Mesenchymal stem cells and COVID-19: the process of discovery and of translation.

ABSTRACT

Mesenchymal stem cells were developed as a cell-based therapeutic in the 1990's. The translation of culture expanded mesenchymal stem cells from a basic science focus into a modern therapeutic has taken 30 years. The current state of the basic science information argues that mesenchymal stem cells may be curative for coronavirus disease 2019 (COVID-19). Indeed, early small-scale clinical trials have shown positive results. The issue raised is how to assemble the resources to get this cell-based therapy approved for clinical use. The technology is complex, the COVID-19 viral infections are life threatening, the cost is high, but human life is precious. What will it take to perfect this potentially curative technology?
