First Stem Cells Extracted from Cloned Human EmbryoPosted: 02.17.04Scientists in South Korea have extracted stem cells from a cloned human embryo - a breakthrough that has potential for treating various diseases but also ignites fears that rogue scientists will use the technology to clone humans.
Part I: Pre-Reading Task
Other scientists have cloned small numbers of human embryos that lived for a short time, but the South Koreans who announced their work last week in the journal Science, apparently succeeded on a scale that far outstripped earlier human cloning efforts.
The scientists next took body cells from the same women who had donated the egg cells. The body cells have two sets of chromosomes, the full genetic blueprint needed to create a human being. The scientists removed these body cells' nuclear material and placed it into the egg cells.
