Dec. 29, 2005 -- South Korean laboratories used by scientist Hwang Woo Suk no longer have any stem cells created from patients' tissues, the result of the researcher's landmark May 2005 paper, the Seoul National University said. (blogspot.com)
``The patient-matching stem cells no longer exist,'' Roe Jung Hye, dean of research of affairs at the university, said in an e-mailed statement. (blogspot.com)
The stem cells in storage at Hwang's laboratories at the university were all derived from the fertility clinic MizMedi's blastocysts, which were generated by in vitro fertilization . (blogspot.com)
Hwang's stem cells should have been found to be nuclear transferred embryonic stem cells from patients' skin cells. (blogspot.com)

Cloning as a practice is not a new idea. (thesized.com)
Scientists unaffiliated with the experiment say the limited success rate of the procedure suggests more work is needed before this practice becomes common. (cmaaa.co.za)

Dolly was an important milestone, inspiring scientists to continue improving cloning technology as well as to pursue new concepts in stem cell research. (wptv.com)

The newly discovered obstacle makes it more likely than ever that rogue scientists' recent claims to have created cloned babies were fraud. (irfi.org)

The endgame was never meant to be armies of genetically identical livestock: Rather, researchers continue to refine the techniques and combine them with other methods to turbocharge traditional animal breeding methods as well as gain insights into aging and disease. (wptv.com)
The present report gives an overview of the terms and methods used in cloning and summarizes the debates in the General Assembly. (who.int)
According to him, their research is primarily aimed at improving methods of treating cancer, immunity disorders and other genetically induced conditions. (blastingnews.com)

However, by the time the fertilized egg divides into 8 or 16 cells something changes and each respective cell, if separated, no longer has the potential to create a fetus. (jcpa.org)

This pattern goes on so that each of the trillions of cells in an adult is genetically exactly the same - whether it's in a lung or a bone or the blood. (wptv.com)

How similar are clones? (thesized.com)
Scientists hope the findings will lead to a similar treatment being rolled out to people within the next 20 years. (ndriromaric.com)

Cold Spring Harbor, NY -- Cold Spring Harbor Laboratory Press (CSHLP) announced the release of The Digital Cell: Cell Biology as a Data Science, available on its website in hardcover format. (cshlpress.com)
