    It specifically mentions skin cells.

    I don't know that "embryonic" is necessary to describe stem cells.

      the nucleus from a person's (say your) skin cell into an embryonic cell (coincident with taking out the original nucleus).

      That thereby reprograms the cell to only make YOUR antigens, thus it will avoid immune rejection when re-implanted (which would happen if just any old embryonic stem cell had been used).

      So, this overcomes one hurdle towards using ES cells therapeutically - immune rejection - but doesn't get us any closer to curing any specific disease per se.

      But still, it was published in Cell, so it's a pretty big deal.

        most of my working life.  They can only do it one replicable step at a time.

        The steps may spring from inspiration, but that's the simple part.

        •  In a way this seems to have solved (0+ / 0-)

          a problem - immune rejection - that was already solved in the past 3 or 4 years with the development of iPSCs.

          Or course, there is considerable debate within the scientific community whether iPSCs are functionally equivalent to ES cells . . .

          Overall, they both probably have their strengths and weaknesses so it's good to have both options available - you know, kinda like when you go to vote and can choose Dem or Repub . . . .
