Presentation transcript:

STEM CELLS

 Where do the different cells and tissues in your body come from?  Incredible as it seems, every cell was produced by mitosis from a small number of cells called stem cells

DIFFERENTIATION & SPECIALIZATION

 Stem Cells are unspecialized cells that have the potential to differentiate into a wide variety of cells. WHAT ARE STEM CELLS?

 Medical researchers believe that stem cell therapy has the potential to dramatically change the treatment of human disease.  A number of adult stem cell therapies already exist, particularly bone marrow transplants that are used to treat leukemia. RESEARCH ON STEM CELLS

POTENTIAL USES OF STEM CELLS

 One concern of treatment is the risk that transplanted stem cells could form tumors and become cancerous if cell division continues uncontrollably.  Medical vs. Ethical concerns POTENTIAL PROBLEMS YouTube - A Stem Cell Story
