Background: The prevalence of COVID-19 cases in Indonesia until June 9th 2020, Government has confirmed the number of 32.076 positive cases from 34 provinces in Indonesia with 1.923 fatalities. Along with the development of technology, stem cell-based biological medical therapy, and stem cell-based immunotherapy were developed to find out its potential in the case of COVID-19 treatment besides using chemical drugs as a therapy.Methods: In this study, in vitro research will be conducted to determine the potential of hematopoietic stem cells (HSC) against SARS-CoV-2 (COVID-19) viruses with virus isolates from Indonesia. The SARS-CoV-2 virus was planted in rat kidney cells and Vero cells, then cells that had been planted with the virus were given HSC cells and then evaluated at 24, 48, and 72 hours. The evaluation is done by collecting cells and supernatant from the cell plate and then evaluating the viral load using a Polymerase Chain Reaction (PCR) machine.Results: The results showed that the addition of HSC on cells that had been infected by SARS-CoV-2 decrease in viral load within 24 to 72 hours in all variations of Multiples of Infection (MoI) values.Conclusions: The administration of HSC cells has the potential to eliminate SARS-CoV-2 virus. Although this research is an in vitro study, this study could be the basis for the development of alternative stem cell-based therapies to handle COVID-19 cases in Indonesia.
