The Nobel Prize for stem cell research

The Nobel Committee granted the Nobel Prize in Medicine or Physiology 2012  to the developments made in stem cell research..

This prestigious prize was awarded jointly to S. Yamanaka and Sir J.B. Gurdon "for the discovery that mature cells can be reprogrammed to become pluripotent" Later, these reprogrammed cells can differentiate into a completely different type of cell than before. This is the direction of regenerative medicine, which is looking for ways of transforming stem cells (e.g. from umbilical cord blood) into cells of tissues that have been damaged.
