  1. Activity 14 Stem Cell Differentiation

  2. The Organization of Multicellular Organisms

  3. How do you think all of the specialized cells that make up your body develop?

  4. Read the Introduction. • Cells that have the ability to produce a variety of types of specialized cells are called stem cells. • The process by which stem cells produce specialized cells is called differentiation.

  5. Development of Specialized Cells

  6. Challenge • How do stem cells produce specialized cells?

  7. Only some of the types of stem cells in the body are represented in this activity. • Not all differentiated cell types in the body are represented in this activity. • Many of the molecular differentiation factors represented by the chips are proteins, and are classified as signaling proteins.

  8. Now that you know more about stem cells and differentiation, why do you think scientists think stem cells are the key to replacing diseased or damaged tissues in patients with heart disease, cancer, or diabetes?

  9. Revisit the Challenge • How do stem cells produce specialized cells?

  10. Key Vocabulary • differentiation • stem cells
