Stem cell video reflection

Well on Monday January 10, 2011 we watched a lecture on stem cell research.  Dr. Rosenthal talked mostly about newt's and how they can regenerate entire limbs in about an average period of 70 days.  They can do this because of stem cells.  The Stem cells first close up the wound, then they start rebuilding cell by cell.  All stem cells have a designation when they are finished.  Some become muscle cells other bone then some skin.  This is my basic understanding on how stem cells work in a newt.
