New research out of China aims to one day substitute human milk with modified bovine
milk. In what is surely a huge step for genetically modified foods, scientists
from State Key Laboratory for Agrobiotechnology have 'created' 300 cows that
produce milk containing properties of human breast milk.
With cloning technology, genes expressing human lysozyme
(HLZ) were introduced to the DNA of a sample of Holstein dairy cows before the
embryos were implanted in surrogates. Once the surrogates began lactating,
researchers found that the milk contained HLZ, lactoferrin, and
alpha-lactalbumin proteins . These proteins are typically found in human milk,
and are considered key nutrients for boosting immune systems and reducing the
risk of infections in babies.
Professor Ning Li, head researcher and director of State Key
Laboratories for AgroBiotechnology, insists that the milk is just as safe as
regular milk but has a much stronger taste and higher nutritional content.
Along with collaborators at the Beijing GenProtein
Biotechnology Company, Li has been sampling the modified cows for six months
and has found no significant differences in the amount of fats, proteins,
lactose, and milk solids when compared to regular cow's milk.
They are now testing pasteurization temperatures in hopes
that the milk will be approved by the United States Food and Drug
Administration, among other authorities.
Do you see a future for human-like cow's milk?
