cytostasis
Very LowTechnical/Scientific
Definition
Meaning
The inhibition or stoppage of cell growth and division.
In biology and medicine, a state where cells cease to proliferate, often as a deliberate physiological mechanism or an effect induced by chemical agents, radiation, or other factors. It can be reversible or irreversible and is a key concept in cancer treatment, tissue development, and cellular senescence.
Linguistics
Semantic Notes
Primarily used in cellular biology, oncology, and pharmacology. Implies a controlled or forced halt in the cell cycle, distinct from cell death (cytotoxicity).
Dialectal Variation

Differences
No significant differences in meaning or spelling. The term is international scientific vocabulary.

Examples
By Part of Speech
adjective
British English
- The cytostatic agent prevented further tumour growth.
- They studied the compound's cytostatic effects.
American English
- The cytostatic drug halted cell division.
- Researchers measured the cytostatic activity.
Examples
By CEFR Level
- The goal of some cancer treatments is cytostasis, not necessarily killing the tumour cells.
- Certain chemicals can induce cytostasis in laboratory cell cultures.
- The study demonstrated that the novel compound achieved reversible cytostasis in glioblastoma cells by inhibiting cyclin-dependent kinases.
- Distinguishing between cytostatic and cytotoxic effects is crucial for evaluating the long-term impact of a therapeutic agent.
Learning
Memory Aids
Mnemonic
Imagine a CYST (like a small sac) full of cells that are forced to STAY AS they are (STASIS). CYTO-STAY-SIS = cells staying put, not dividing.
Conceptual Metaphor
CELL DIVISION IS A FACTORY PRODUCTION LINE; cytostasis is a shutdown or pause of the assembly line.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'цитостаз' (direct cognate) – it's correct but very formal. Avoid mixing with 'цитотоксичность' (cytotoxicity), which means cell death, not just halted growth.
Common Mistakes
- Misspelling as 'cytostosis' or 'cytostassis'.
- Confusing it with 'cytotoxicity' (killing cells).
- Using it as a verb (e.g., 'to cytostasis' is incorrect; use 'to induce cytostasis').

FAQ
Frequently Asked Questions
No, cytostasis refers to the stoppage of cell growth and division, which may be reversible. Cell death (cytotoxicity or apoptosis) is an irreversible process where the cell is destroyed.
It is predominantly used in cellular biology, oncology (cancer research), pharmacology (drug development), and immunology.
Yes, in contexts like cancer treatment, inducing cytostasis in tumour cells is a key therapeutic strategy to control the disease. It's also a normal part of tissue homeostasis.
The adjective is 'cytostatic', as in 'a cytostatic drug' or 'cytostatic effect'.
