Researchers Hail Stem Cells Safe for Human Use

Stem-cell science is a fast-moving field. Just three years since a Japanese researcher first reprogrammed ordinary skin cells into stem cells without the use of embryos, scientists at a Massachusetts biotech company have repeated the feat, only this time with a new method that creates the first stem cells safe enough for human use. The achievement brings the potentially lifesaving technology one step closer to real treatments for disease.

Dr. Robert Lanza, chief scientific officer at Advanced Cell Technology (ACT), reported today in the journal Cell that his team has created stem cells using human skin cells and four proteins.

Stem cells for diabetes from cloned embryos

And now there are three: in the wake of announcements from laboratories in Oregon and California that they had created human embryos by cloning cells of living people, a lab in New York announced on Monday that it had done that and more.

In addition to cloning the cells of a woman with diabetes, producing embryos and stem cells that are her perfect genetic matches, scientists got the stem cells to differentiate into cells able to secrete insulin.

That raised hopes for realizing a long-held dream of stem cell research, namely, creating patient-specific replacement cells for people with diabetes, Parkinson’s disease,
