Another team of scientists led by Dr. Josef Penninger of the University of British Columbia invented a medicine called  APN01 and tested it in engineered human tissue, meaning human cells put together in a lab to look and act like they were inside a body. The scientists learned that adding human soluble recombinant angiotensin  converting  enzyme 2 (ACE2) to these tissues infected with SARS-CoV-2 made it harder for the virus to reproduce.
