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.
