fibroblast
Very lowTechnical/Scientific
Definition
Meaning
A type of cell found in connective tissue that produces collagen and other fibres.
A key structural and reparative cell in the body's connective tissue, involved in wound healing, fibrosis, and maintaining the extracellular matrix.
Linguistics
Semantic Notes
Strictly a biological/medical term referring to a specific cell type; not used metaphorically in general language.

Examples
By Part of Speech
verb
British English
- The tissue began to fibroblast, laying down new collagen.
American English
- The wound site will fibroblast as part of the healing process.
adjective
British English
- The fibroblastic activity was measured in the assay.
American English
- They observed a strong fibroblastic response in the sample.
Examples
By CEFR Level
- The doctor explained that fibroblasts are important for healing cuts.
- Research focuses on how activated fibroblasts contribute to pathological scarring and fibrosis in various organs.
Learning
Memory Aids
Mnemonic
Think: FIBRE + BLAST. It's a cell that 'blasts' or produces the fibres (like collagen) of our connective tissue.
Conceptual Metaphor
The body's builder/bricklayer: a cell that lays down the structural scaffolding (extracellular matrix) for tissues.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'фибробласт' as a general term for 'connective tissue'; it refers specifically to the cell type.
- Do not confuse with 'fibrocyte', a less active state of the same cell.
Common Mistakes
- Misspelling as 'fibroblast' (missing 'r').
- Using it as a general term for any cell in connective tissue (it's specific).
- Pronouncing it as /ˈfɪb.rə.blæst/ (the first syllable is 'fy' as in 'fibre').

FAQ
Frequently Asked Questions
No. Fibroblasts are differentiated cells with a specific function (producing extracellular matrix). While some may have limited plasticity, they are not classified as pluripotent stem cells.
No. Fibroblasts are microscopic cells. They are visible only under a microscope.
The primary products are collagen and other components of the extracellular matrix, such as elastin and fibronectin.
Almost never. It is a highly specialised scientific term with no common metaphorical or general language use.
