Fibroblasts
Fibroblasts — the primary cells of the dermis, responsible for producing collagen, elastin, and other components of the extracellular matrix that give skin its structure and elasticity. They play a central role in wound healing and in maintaining the firmness and resilience of skin over time. Their activity naturally declines with age, contributing to visible changes in the skin.
Key points
- Fibroblasts are the main connective-tissue cells found in the dermis.
- They synthesize collagen, elastin, and glycosaminoglycans that form the skin's supportive extracellular matrix.
- Fibroblasts are essential to wound healing, producing new matrix to repair damaged tissue.
- Their production of collagen and elastin gradually slows with age, contributing to reduced firmness and elasticity.
Frequently asked
What is the main function of fibroblasts?
Fibroblasts produce collagen, elastin, and other matrix components that give the dermis its structure, strength, and elasticity.
Why do fibroblasts matter for aging skin?
As fibroblast activity declines with age, less collagen and elastin are produced, which contributes to thinning, reduced firmness, and the formation of wrinkles.
