Chinese scientists have made a breakthrough in transgene fields by creating sheep with human genes, according to a press conference held in Beijing Sunday.

The three sheep, two male and one female, are now living in the Shunyi county in Beijing, said scientists from the China Agricultural University.

The transgenic sheep were created through the "sheep mammary bio-reactor" project, which integrated some human genes with the embryo of a sheep.

The project started in 1998. Four transgenic sheep were born this June, but one female died three days later.

Through the use of transgenosis technology, scientists said, people are able to obtain valuable protein and medicine from the milk of the transgenic sheep.
