For immediate release
A research institution in China is going to sell gene-edited micropigs as pets, according to Nature News. The pigs were originally developed as models for human disease. Researchers used TALENs, a gene-editing tool used to make precise changes to DNA, to disable genes responsible for growth in fetal pig cells so that the pigs only grow to around 15kgs. The pigs were original created for research but now the group that created them, BGI (Beijing Genomics Institute), have announced that they would like to sell the tailor-made animals as pets. Below Australian and US scientists react to the news.
