    A culture can change in several ways: cells may become larger, divide, specialize, stop dividing, or die. These changes are related, but they do not mean the same thing. This chapter connects cell structures, the cell cycle, signaling, and gene expression with growth and development. It also introduces stem cell self-renewal and potency. Understanding these processes helps you choose measurements that reveal what cells are doing and explain changes without drawing conclusions beyond the evidence.

    Learning Objectives
    • After completing this chapter, you should be able to:

      1. Match cell lysates, RNA samples, and conditioned medium to appropriate biological questions and assays.

      2. Trace samples to their source cultures and explain how collection and preservation affect interpretation.

      3. Distinguish extracellular vesicle enrichment, concentration, and recovery, and calculate basic TFF processing measures.

      4. Explain reverse transcription and qPCR controls and calculate relative RNA abundance when assay requirements are met.

      5. Interpret SDS-PAGE and immunoblot results using size references, specificity controls, and loading normalization.

      6. Calculate cytokine concentration from an ELISA result and assess conclusions across RNA, protein, and functional measurements.
