Study Notes
Cell Proliferation and Integrity
- The term for a cell's capacity for sustained proliferation and generation of numerous progeny is "cellular immortality."
- Differentiated cells are considered dead when they can no longer divide or perform their specific functions effectively.
Reproductive Death and Cell Integrity
- Reproductive death indicates that a cell has lost its ability to undergo division and generate new cells, even if it remains metabolically active.
- Stem cells and certain types of progenitor cells are capable of retaining reproductive integrity, allowing them to proliferate indefinitely.
Cell Survival and Death Definitions
- A cell survival curve graphically represents the relationship between the dose of a lethal agent and the fraction of surviving cells, helping assess cell resilience.
- Proliferating cells are defined as dead when they lose the ability to reproduce, regardless of their metabolic status.
Summary of Key Concepts
- Reproductive integrity is a critical characteristic of stem cells, allowing them to divide indefinitely in contrast to differentiated cells.
- Understanding definitions of death in both differentiated and proliferating cells is essential for studies in cell biology and cancer research.
