Which type of cell is primarily involved in the repair of injured tissues?

Fibroblasts play a crucial role in the repair of injured tissues due to their ability to produce the extracellular matrix and collagen, which form the structural framework for tissue healing. When an injury occurs, fibroblasts migrate to the site of damage where they proliferate and synthesize various proteins that are essential for tissue regeneration. These cells not only facilitate the restoration of the tissue architecture but also secrete growth factors that aid in the healing process and attract other necessary cells to the injury site.

This makes fibroblasts central to wound healing and tissue repair, as they help restore the functional integrity of the damaged tissue. Their activity is vital in both acute and chronic wound healing processes, working collaboratively with other cell types such as endothelial cells, immune cells, and epithelial cells to ensure proper healing and restoration of tissue function after injury.
