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.
