    Cells in a culture may become larger, divide, specialize, stop dividing, or die. These changes can occur together, but each answers a different biological question. This chapter connects cell structure, the cell cycle, signaling, and gene expression to those changes. It also explains stem cell self-renewal and potency. You will learn to choose measurements that show what cells are doing and support a clear interpretation.

    Learning Objectives

    After completing this chapter, you should be able to:

    1. Connect major mammalian cell structures to growth, signaling, and cell behavior.

    2. Distinguish cell growth, proliferation, differentiation, and cell death.

    3. Describe the major stages of the cell cycle and explain the purpose of checkpoints.

    4. Explain how gene expression and environmental signals guide development.

    5. Compare stem cell self-renewal, potency, and directed differentiation.

    6. Interpret changes in cultured cells while considering senescence, cancer-related changes, and measurement limits.
