科技英语新闻:Regulating human-anmal cells hybrid called for

BEIJING, July 26 (Xinhuanet) -- Some forms of medical research involving animals containing human material should be more tightly regulated, a report warned.

The warning was issued on Friday by an expert working group from the Academy of Medical Sciences in Britain.

The report suggested the ban of the use of animal cells that can produce human sperm or egg cells.

"We don't want scientists to cause problems for the future by overstepping the mark of what is publicly acceptable," said Professor Robin Lovell-Badge, a member of the expert working group.

The controversy partly originated from a medical research in Britain. Three years ago, the researchers produced human embryos with the nucleus hollowed cow eggs, according to the Associated Press.

"This is a complex research area and there should be an ongoing dialogue between scientists, regulators and the wider public to address emerging issues." said Martin Bobrow, a professor of medical genetics at the University of Cambridge.
