What is the primary goal of the proliferation phase?

• A. Inflammation reduction and scar formation.
• B. Pain control and edema reduction.
• C. New tissue formation, including fibroblasts, capillaries, and granulation tissue, covered by epithelial cells.
• D. Complete regeneration with no scar.

Answer: (C)

The proliferation phase is about rebuilding tissue to fill the wound and restore the barrier. Fibroblasts migrate into the wound and lay down new collagen, forming the extracellular matrix. New capillaries form (angiogenesis), creating a network that supplies the healing tissue. Granulation tissue—characterized by its pink, granular appearance—fills the wound bed and provides a foundation for epithelial cells to migrate over and re-epithelialize the surface. This combination strengthens the area and prepares it for remodeling. It’s not primarily about reducing inflammation (that happens earlier) or just controlling pain and edema, and complete regeneration with no scar is not typical in most adult skin wounds. The description of new tissue formation with fibroblasts, capillaries, granulation tissue, and epithelial coverage best captures the goal of the proliferation phase.
