As of May 11th 2020, the coronavirus disease 2019 (COVID-19) pandemic, caused by the novel, the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has caused 274,361 deaths out of 3,917,366 (7% case fatality rate). As with the two other novel coronavirus zoonotic diseases of humans, SARS and MERS, no specific treatments for reducing mortality or morbidity are yet available. Deaths from COVID-19 will continue to rise globally until effective and appropriate treatments and vaccines are found. With no specific treatments being available for treating COVID-19 patients, the global medical, scientific, pharma and funding communities have rapidly initiated over 500 COVID-19 clinical on a range of antiviral drug regimens, biologics, repurposed drugs in various combinations. We focus this editorial specifically on the background to, and the rationale for, the use and evaluation of mesenchymal stromal (Stem) cells (MSCs) in treatment trials of patients with severe COVID-19 disease. This is an area which has been eclipsed by the current emphasis the huge number of trials evaluating new anti-viral drugs, repurposed drugs and combinations thereof. MSCs should also be trialed for treatment of severe cases of MERS where mortality rates are upto 34% and MERS-CoV remains a WHO priority Blueprint pathogen. It's about time funding agencies now invest more into development MSCs per se and other host-directed therapies in combination with other therapeutic interventions. MSC therapy could turn out to be an important contribution to bringing an end to the high COVID-19 and MERS death rates.
