Explore the fascinating process of how stem cells develop into specialized cells, forming the diverse tissues of multicellular organisms. This activity delves into the mechanisms of differentiation, where stem cells produce various cell types, including those in the heart, cancer, and diabetes treatments. You'll engage with molecular differentiation factors, particularly signaling proteins, that guide this process. Why do scientists believe stem cells hold the potential for regenerative medicine? Discover the answer through this enlightening exploration of cellular development.

Activity 14 Stem Cell Differentiation
How do you think all of the specialized cells that make up your body develop?
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.
Challenge • How do stem cells produce specialized cells?
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.
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?
