Scientists Are 3D Printing Miniature Human Organs To Test COVID-19 Drugs

Scientists are conducting preliminary tests of COVID-19 drugs using 3D printed human organs, eliminating the need to perform tests on animals, or, of course, humans. The Week reports: For example, Anthony Atala, the director of the Wake Forest Institute for Regenerative Medicine, and his team are using 3-D printers to create tiny replicas of human organs, including miniature lungs and colons, which are particularly affected by the coronavirus. They send them overnight for testing at a biosafety lab at George Mason University. The idea predated the coronavirus -- Atala said he never thought "we'd be considering this for a pandemic" -- but it could come in handy and help expedite the experimental drug process, especially since Atala said his Winston-Salem, North Carolina-based lab can churn out thousands of printed organs per hour. "The 3-D models can circumvent animal testing and make the pathway stronger from the lab to the clinic," said Akhilesh Gaharwar, who directs a lab in the biomedical engineering at Texas A&M University.
