Scientists get closer to making personalized blood cells by using patients' own stem cells

New research has nudged scientists closer to one of regenerative medicine’s holy grails: the ability to create customized human stem cells capable of forming blood that would be safe for patients.

Advances reported Wednesday in the journal Nature could not only give scientists a window on what goes wrong in such blood cancers as leukemia, lymphoma and myeloma but also could improve the treatment of those cancers, which affect some 1.2 million Americans.

The stem cells that give rise to our blood are a mysterious wellspring of life. In principle, just one of these primitive cells can create much of a human being’s immune system, not to mention the complex slurry of cells that...
