1. Stem Cells

2. 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

3. Differentiation & Specialization

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

5. Research on 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.

7. Potential uses of stem cells

8. Medical vs. Ethical concerns
Potential problems
One concern of treatment is the risk that transplanted stem cells could form tumors and become cancerous if cell division continues uncontrollably.
