Quite amazing! Doubtful we'll see any Animal Farm animals. The modified genes are for mostly endothelial modifications. >> The Yucatan miniature pig breed was chosen because its organ sizes are comparable to human organs28. In addition, pigs with OO blood type were selected to eliminate ABO blood-type incompatibilities29. >> The pigs were engineered to carry 69 genomic edits, using the clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated protein 9 (Cas9)-mediated nonhomologous end joining and homology-directed repair30,31, and recombinase-mediated cassette exchange. https://www.nature.com/articles/s41586-023-06594-4 https://www.nature.com/articles/s41586-023-06594-4
