i read the article. From what i was able to tell, embryonic stem cells are NOT the concern of the research, rather, it is the patient's own stem cells. It deals with differentiating the patient's healthy stem cells from the cancerous stem cells, and eradicates the latter.

Did you read comment# 1? It had the title of the Nature Biotechnology article: "Characterization of human embryonic stem cells with features of neoplastic progression"

No ethical concerns here.

Really? I'm not so sure about that. I'd be happily surprised to learn that human embryonic stem cells can be characterized with using destructive techniques.

Correction, it should have been: "Really? I'm not so sure about that. I'd be happily surprised to learn that human embryonic stem cells can be characterized without using destructive techniques.
