Adult 'stem cells'

The cells were found in the bone marrow of adults by Catherine Verfaillie at the University of Minnesota. Extraordinary claims require extraordinary proof, and though the team has so far published little, a patent application seen by New Scientist shows the team has carried out extensive experiments.

These confirm that the cells - dubbed multipotent adult progenitor cells, or MAPCs - have the same potential as ESCs. "It's very dramatic, the kinds of observations [Verfaillie] is reporting," says Irving Weissman of Stanford University. "The findings, if reproducible, are remarkable."

For further reference the President's Bioethics Council has a paper regarding adult "stem cells" and their possibilities.
