  1. Stem Cells Biotechnology

  2. All cells have all your DNA inside them • Once a cell becomes a certain type of cell, it has specialized. • At this point it can “shut down” genes that it doesn’t need (ex: skin cells can shut down the genes that tell the heart how to beat) so they can only become that one type of cell • Stem Cells are cells that have not “shut down” any DNA ~ So they can become any type of cell. Why are stem cells important?

  3. New technology with stem cells… • http://www.cbsnews.com/8301-3445_162-3960219.html

  4. Stem cells can be found in developing embryos • This causes debate because the embryo can not develop into an offspring if the stem cells are used. • Stem cells are harder to find in adults, but can be found in bone marrow Where do you find stem cells?

  5. Scientists are studying ways to use stem cells to repair damaged tissue in a body. • http://www.msnbc.msn.com/id/22635550/ns/health-heart_health/t/scientists-grow-rat-heart-lab/ How can Stem cells repair tissues?
