Human embryos successfully cloned (sort of)

posted by Jason Kottke   May 16, 2013

A group of researchers in Oregon have successfully cloned human embryos. No, really:

The researchers, at Oregon Health and Science University, took skin cells from a baby with a genetic disease and fused them with donated human eggs to create human embryos that were genetically identical to the 8-month-old. They then extracted stem cells from those embryos.

The embryo-creation technique is essentially the same as that used to create Dolly the sheep and the many cloned animals that have followed. In those cases, the embryos were implanted in the wombs of surrogate mothers.

These embryos won’t work for producing clones humans…they are being used to harvest stem cells.

The Oregon researchers, who published a paper on their work in the journal Cell, say their goal is what has been called therapeutic cloning: making embryonic stem cells that are genetically identical to a particular patient.

Embryonic stem cells can turn into any type of cell in the body, like heart cells, muscles or neurons. That raises the hope that one day the cells will be turned into replacement tissue or even replacement organs to treat a host of diseases.
