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