Fibroblast

Part of speech: noun

Pronunciation: /ˈfaɪ.brəˌblɑːst/

Definitions

1. A specific cell type responsible for generating connective tissue, which includes producing collagen and other fibers in the extracellular matrix, while participating in tissue repair and structure maintenance
2. This unique cell serves as a key producer of connective tissue components such as collagen and fibers within the extracellular matrix, contributing significantly to wound healing and structural integrity of tissues
3. A specialized cell that plays a crucial role in synthesizing components of connective tissue, including collagen and fibers, while also aiding in repairing tissues and maintaining structure

Etymology: Fibroblast is a compound built from two Greek-derived parts. The first, "fibro-", comes from Latin "fibra", meaning a filament or fibre, and the second, "-blast", comes from Greek "blastos", meaning a bud, sprout or germ. Put together, the name describes a cell that gives rise to fibres, which is exactly what these cells do: they produce the collagen and other fibrous proteins that form connective tissue. The "-blast" element is a useful clue to how the word works across biology. It marks a young or precursor cell that generates a finished structure, so you will find it in other terms such as "osteoblast", a cell that builds bone, and "chondroblast", a cell that forms cartilage. Fibroblast follows the same pattern, naming the cell by the material it makes. The term is a modern scientific coinage built from classical roots, not a word the ancient Greeks or Romans used for anything like this cell. Its parts are old, but the combined name belongs to the period when microscopy and cell biology were developing.

Synonyms: cell, connective tissue cell
