Scientists from he China Agricultural University have introduced human genes into 300 dairy cows to produce milk with the same properties as human breast milk. Using cloning technology, scientists brought human genes into the DNA of Holstein dairy cows before genetically-modified embryos were implanted into surrogate cows.
So far, the Chinese scientists successfully created cows that contains human milk proteins lysozyme, lactoferrin, and alpha-lactalbumin. It might take more than ten years until this cow-produced human milk will be commercially available.
