Scientists create gene-edited dogs from cloned skin cells

Two beagle dogs created from cloned skin cells were born in South Korea, which were

altered by gene editing.


Scientists hope that this method can be used to eliminate disease-causing mutations in purebred dogs.

First, the researchers edited the genes of cellsskin to change the DJ-1 gene associated with diseases such as Parkinson's disease. The scientists then added several genes, including one for a fluorescent protein, to make it easier to tell which cells were successfully edited. The team then placed these gene-edited cells next to eggs whose DNA had been removed and used short bursts of electricity to fuse them together.

A total of 68 embryos were created.They were implanted in six different surrogate mothers. As a result, two puppies were born. They are now 22 months old and have no anomalies. However, you should keep an eye on the dogs.
