Oregon scientists get stem cells from cloned human embryos

Oregon scientists get stem cells from cloned human embryos

A team of researchers said Wednesday that it had produced embryonic stem cells — a possible source of disease-fighting spare parts — from a cloned human embryo. Scientists at the Oregon Health and Science University accomplished in humans what has been done over the past 15 years in sheep, mice, cattle and several other species. The achievement is likely to, at least temporarily, reawaken worries about “reproductive cloning” — the production of one-parent duplicate humans. But few experts think that…

“Gold standard” stem cells created by British scientists

“Gold standard” stem cells created by British scientists

British scientists have created the first known batch of “gold standard” stem cells which could one day lead to a new wave of treatments for degenerative diseases. The stem cells, taken from human embryos and grown in the lab, are of unprecedented quality and could be offered to researchers before the end of next year for eventual use in clinical trials. Previous embryonic stem cell (ESC) trials in humans have used lower-quality “research grade” cells, which are manipulated and reclassified…
