Definition
Meaning and Definition
The process by which two or more biological cells merge to form a single hybrid cell, combining their cellular contents (cytoplasm and sometimes nuclei).
A laboratory technique used in biotechnology, genetic engineering, and immunology to create hybrid cells (e.g., hybridomas for monoclonal antibody production, or somatic cell hybrids for genetic mapping). The term can also be used metaphorically in technology or business contexts to describe the merging of distinct units or systems.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or spelling. Both varieties use the same term. Minor potential differences in laboratory protocol terminology do not affect the core term.
Connotations
Identical technical connotations in both varieties.
Frequency
Equally low in general English, equally high in relevant scientific disciplines in both the UK and US.

Common Mistakes When Using “cell fusion”
- Misspelling as 'cell infusion' (which means to put something *into* a cell).
- Using it as a verb ('to cell-fuse') instead of the standard nominal form or the verb 'fuse cells'.
- Confusing it with 'nuclear fusion' (a physics process).
FAQ
Frequently Asked Questions
Fertilisation involves a specific type of cell fusion (between sperm and egg), but 'cell fusion' is a broader term covering many other biological and artificial processes.
No, typically cells need to be of compatible types or treated with specific agents (like viruses or chemicals) to overcome membrane barriers and allow fusion.
A hybrid cell, which may initially contain nuclei from both parent cells (a heterokaryon) and a blended cytoplasm. This can later give rise to a hybrid cell with a single, combined nucleus (a synkaryon).
In academic textbooks, research articles, and laboratory protocols within the fields of cell biology, immunology, biotechnology, and genetics.
The process by which two or more biological cells merge to form a single hybrid cell, combining their cellular contents (cytoplasm and sometimes nuclei).
Cell fusion is usually technical/scientific, academic. in register.

Mnemonic
Think of a science lab where two CELLs are FUSED together like two beads of melting glass, becoming one new, combined cell.
Conceptual Metaphor
CELLS ARE COMPARTMENTS/ENTITIES; FUSION IS BLENDING/MERGING. The process is conceptualised as the breaking of boundaries between discrete units to create a new, integrated whole.
