Fibroblasts are specialized cells that help produce extracellular matrix, synthesize collagen, and play a pivotal role in wound healing. Fibroblasts are among the most common cells in mammalian connective skin tissue.
Fibroblasts can exist in another state known as fibrocytes in which they are noted as being inactive. Fibrocytes are more involved in tissue metabolism and maintenance.
The main role of fibroblasts is to continuously supply precursor compounds for the extracellular matrix. This ensures that joints work, the skin retains elasticity, and wounds heal properly.
