The announcement by Worcester, Massachusetts-based Advanced Cell Technology that its researchers had created cloned human embryos has set of a new round in the debates over cloning technology. ACT claims its work, reported in the 25 November 2001 issue of the Journal of Regenerative Medicine, is not aimed a producing fully-developed cloned humans, but at producing stem cells that can be used for generating individualized new tissues for therapeutic use. However, ACT also announced in a report in the 22 November 2001 issue of Science that its proprietary cloning technology has been used to produce healthy and normal adult animals (in this case, cattle).
Some additional background may be found in these articles from Reuters News Service on ACTís announcement, the renewed debate, and the companyís goals for therapeutic cloning.
