Organoids in COVID-19: Can we break the glass ceiling?

COVID-19 emerged in Sep 2020 as a disease caused by the virus SARS-CoV-2. The disease presented as pneumonia at first, but later was shown to cause multi-system infections and long-term complications. Many efforts have been put into discovering the exact pathogenesis of the disease. In this review, we aim to discuss an emerging tool in disease modelling, organoids in the investigation of COVID-19. This review will introduce some methods and breakthroughs achieved by organoids and the limitations of this system.
