A new startup company, eGenesis, from Harvard Medical School’s George Church, is working to modify pigs to create organs suitable for transplant into humans. The startup will be taking a two-pronged approach; one line of pigs will be developed to lack risky viruses and a second line will be modified to have a “humanized” immune system. The two lines will then be merged into a single line for further study. While this approach holds promise, years of testing and clinical trials will be needed before widespread adoption.
