Animal Eggs "To Grow Stem Cells"

Stem cell researchers are looking to use animal eggs as 'hosts' to grow human cells. A Chinese team has already claimed to have created human embryonic stem cells using rabbit eggs which had had their genetic material removed. UK experts said the option had to be considered because there were too few human eggs for research. Scientists say cells created using animal eggs would only be used in the lab, but critics condemned the plan. The recent controversy over South Korean researcher, Hwang Woo-suk, has added impetus to the need to find new sources of eggs, scientists say. For more information.
