Scientists worked to modify the pig DNA so that organ transplants from pig to human can be easier. Consequently, there is a high possibility that people who need a transplant of an organ will be going to their pig farm.
Here’s it, while it may not be too easy, researchers have come up with some form of editing in pig DNA, and this gives hope of using pig organs in humans. These organs are almost the same size, and work similar to the human organs, making scientists think it’s a big step ahead.
Retrovirus halted the movement years ago
While this is not an entirely new movement, it was suspended in the late 90’s when a form of retrovirus was discovered in the pig DNA.
Researchers identified that such retrovirus could be passed from pig to humans if transplant occurs. And if this retrovirus is passed, it could cause tumors or immunodeficiency. However, doctors have transplanted significant parts such as the pancreas cells and heart valves in humans, but no infection showed up.
The new movement
Presently, researchers have employed CRISPR to annul the retroviruses found in the DNA of a pig cell. These scientists placed the cell in an egg, and it grew into an embryo and later formed piglets. And these piglets appeared healthy with the edited DNA.
The piglets formed were identical to the pig that had the utilized cell regarding genes. As such, the researchers didn’t only achieve the gene editing but also formed clones.
However, there are still research works necessary to be carried out before pig organ transplants to human can be proved absolutely safe. The study leader informed The New York Times that the first transplant could be possible by the next two years.
