What is the main function of fibroblastic cells during wound healing?

The main function of fibroblastic cells during wound healing is to begin synthesizing an extracellular matrix. Fibroblasts play a critical role in the repair process by producing collagen and other components of the extracellular matrix, which provide structural support to tissues and facilitate the healing of wounds. This matrix is essential for cell adhesion, migration, and overall tissue remodeling. As fibroblasts proliferate and function in this way, they contribute significantly to the closure of wounds and the restoration of tissue integrity.

While other cell types and processes are involved in wound healing—such as inflammatory cytokine production, tissue clearance, and calcification—these activities are primarily associated with different phases or types of cells within the healing response. In contrast, the primary role of fibroblasts is clearly tied to the formation and stabilization of new tissue through the synthesis of the extracellular matrix.
