Scientists in Argentina have created the world’s first cow with two human genes that will enable it to produce human-like milk.
Genetic engineering was used to introduce the “mothers’ milk” genes into the animal before birth,according to the National Institute of Agribusiness Technology in Buenos Aires.
As an adult,the cloned cow “will produce milk that is similar to that of humans”,which will prove “a development of great importance for the nutrition of infants(婴儿)”,said the institute.“The cloned cow,named Rosita ISA,is the first in the world with two human genes that contain the proteins present in human milk,”said the statement.
In April,scientists in China published details of research showing that they had created dairy cows which produced milk containing proteins found in human breast milk.But the Argentine team said the Chinese only introduced one human gene, while their research involved two,meaning the milk will more closely resemble that of humans.
“Our goal was to raise the nutrition value of cows’ milk by adding two human genes,which do good to the immune system of infants,”said Adrian Mutto,from the National University of San Martin which worked with the institute.
Cristina Kirchner,President of Argentina,said the scientific institute made all Argentines proud.She also said that she had rejected the “honor” of having the cow named after her.“They came to tell me that the name is Cristina,but what woman would like to have a cow named after her?It appeared to me to be more proper to call it Rosita.”
