Which cell type is responsible for producing collagen fibers in connective tissue?

• A. Macrophage
• B. Fibroblast
• C. Adipocyte
• D. Plasma cell

Answer: (B)

In connective tissue, collagen fibers are made by fibroblasts. These cells are the main producers of the extracellular matrix, secreting collagen precursors into the surrounding space where they’re built into collagen fibers that give tissue its strength and structure. Fibroblasts are the most common resident cells in connective tissue proper and also synthesize other matrix components like elastin and ground substance. Macrophages are immune cells involved in defense and remodeling, adipocytes store fat, and plasma cells produce antibodies. So the cell responsible for collagen fiber production is the fibroblast.
