Genetically modified cows producing human breast milk
Currently cow milk is not readily digested and absorbed by human infants, so for those mothers who choose not to breastfeed or who are unable, the only current alternative is formula. Many argue that infant formula is inadequate in providing the full nutrients an infant needs. Human milk contains numerous proteins as well as human lysozyme (HLZ), which is a key in fighting bacteria and boosting an infant’s immune system.
With this in mind, Li and his team introduced human lysozyme and other human proteins into the embryos of Holstein cattle and then placed these embryos into surrogate cows. In this recent study, printed in Public Library of Science One, the researchers state that it was cloning technology used to introduce the human genes into the cows DNA. When these genetically modified cows started lactating, the milk they produced contained HLZ as well as other human proteins such as lactoferrin and lactalbumin which also help to boost an infant’s immune system
