Reengineering Life
A Startup Is Making Thousands of Gene-Edited Pigs Because Humans Need Their Organs
Scientists are using CRISPR to address the global organ shortage
Reengineering Life is a series from Future Human about the astonishing ways genetic technology is changing humanity and the world around us.
More than 109,000 people are currently waiting to get a donor organ in the United States. Last year, however, only 39,718 total transplants were performed. Thousands of people will die before they can get the lifesaving transplants they need.
To meet this need, some researchers are attempting to genetically engineer pigs to make their organs suitable for people. Previous efforts to transplant whole animal organs into people have failed, but the gene-editing tool CRISPR could bring the idea closer to reality.
Pig organs aren’t naturally compatible with human bodies. To make them a better fit, scientists at a Chinese biotech startup co-founded by Harvard genetics pioneer George Church, PhD, have used CRISPR to make 42 simultaneous modifications across 13 genes in pigs. The company, Qihan Biotech, has been experimenting with different edits since its formation in 2017. This latest version, which it dubs “pig 3.0,” is the most…
