Apr 9, 2024 · It can be physiological, which occurs in normal tissues or organs, or pathological, i.e., in disease states. In this article, we will consider how the sizes of cell populations are controlled, how cells and tissues can adapt in response to stressors and how these processes can result in disease.
Jun 7, 2020 · Biological cells are adaptive. Change their environment and they respond. In homeostasis, a cell returns to a stable state after it has been perturbed. In evolution, a population of cells becomes better suited to new circumstances.

Adaptation, in biology, the process by which a species becomes fitted to its environment; it is the result of natural selection’s acting upon heritable variation over several generations. Organisms are adapted to their environments in a variety of ways, such as in their structure, physiology, and genetics.
A distinctive feature of many biological systems is their ability to adapt to persistent stimuli or disturbances that would otherwise drive them away from a desirable steady state. The resulting stasis enables organisms to function reliably while being subjected to very different external environments.

In cell biology and pathophysiology, cellular adaptation refers to changes made by a cell in response to adverse or varying environmental changes. The adaptation may be physiologic (normal) or pathologic (abnormal).
Cell culture or tissue culture is the process by which cells are grown under controlled conditions, generally outside of their natural environment. After cells of interest have been isolated from living tissue, they can subsequently be maintained under carefully controlled conditions.
Feb 21, 2023 · Cultured primary cells and continuous cell lines are indispensable in investigations of basic, biomedical, and translation research. However, despite their important role, cell lines are frequently misidentified or contaminated by other cells, bacteria, fungi, yeast, viruses, or chemicals.
