Fibroblasts play a crucial role in the wound healing process, particularly during the proliferation phase. These cells begin to show up in the wound area approximately 2 to 3 days after the initial injury. This timing coincides with the transition from the inflammatory phase, where leukocytes and platelets are primarily active, to the proliferation phase, characterized by tissue formation.

During the proliferation phase, fibroblasts proliferate and synthesize extracellular matrix components, including collagen, which is essential for providing structure and support to the newly formed tissue. This is a pivotal point in healing as fibroblasts contribute significantly to the overall strength and integrity of the wound. Their appearance marks the beginning of a more organized repair process, where tissue regeneration becomes possible.

Understanding this timeline is important for rehabilitation practices, as it guides clinicians on when to begin mobilization and therapeutic interventions that can impact the healing trajectory.
