We can get embryonic stem cells… by cloning adults.

Nature introduces yet another ethical wrinkle into the production of stem cells, with new techniques to create cell-generating embryos from adult cells:

On 17 April, researchers led by Young Gie Chung and Dong Ryul Lee at the CHA University in Seoul reported in Cell Stem Cell that they had cloned embryonic stem-cell (ES cell) lines made using nuclei from two healthy men, aged 35 and 752. And in a paper published on Nature‘s website today, a team led by regenerative medicine specialist Dieter Egli at the New York Stem Cell Foundation Research Institute describes ES cells derived from a cloned embryo containing the DNA from a 32-year-old woman with type 1 diabetes. The researchers also succeeded in differentiating these ES cells into insulin-producing cells.

At present, studies to test potential cell therapies derived from ES cells are more likely to gain regulatory approval than those testing therapies derived from induced pluripotent stem (iPS) cells, which are made by adding genes to adult cells to reprogram them to an embryonic-like state. Compared with iPS cells, ES cells are less variable, says Lovell-Badge. Therapies for spinal-cord injury and eye disease using non-cloned ES cells have already been tested in human trials. But while many ES cell lines have been made using embryos left over from fertility treatments, stem cells made from cloned adult cells are genetically matched to patients and so are at less risk of being rejected when transplanted.

That last bit is the important part. The adults in question… they can be the ones who need the therapy.
