Collagen plays a crucial role in wound healing primarily by providing structure and strength to the healing tissue. During the healing process, collagen is synthesized by fibroblasts and forms a framework that supports new tissue formation. It is essential for the structural integrity of the newly formed tissue, allowing for tensile strength and resilience as the wound closes and heals. This structural support helps to stabilize the area, ensuring that other cells can migrate and proliferate effectively to promote healing. While collagen also has an indirect effect on scarring—since proper collagen formation can help minimize excessive scarring—the primary purpose and characteristic role of collagen in healing is its ability to provide strength and structure. Thus, its critical nature in creating a robust scaffold for tissue repair is central to understanding its function in wound healing.
