Several biotech companies are racing to develop a supply of cloned pigs whose DNA has been genetically modified so they won’t be rejected by the human body, spread pig viruses to people or cause other complications.
The eGenesis pigs are bred with 69 genetic modifications to prepare organs for human transplantation. The changes protect against a virus known to infect pigs as well as delete pig genes and add human genes to make the organs compatible with people.
I recall some groups trying xenotransplantation in the past, but the patients’ own immune systems always rejected the transplanted organ after only a short time. Glad to see that we’re starting to find solutions to this.
