Cloning Humans to Harvest Stem Cells

NPR's Jennifer Ludden talks with NPR's Joe Palca about recent advances in the field of cloning. In 2004, South Korean scientists successfully cloned a human embryo and extracted stem cells from it. Scientists hope to use embryonic stem cells to develop therapies for diseases like diabetes or Parkinson's.
