Wound edges that are well-approximated indicate normal contraction mediated by myofibroblasts. This tissue fills the wound bed from the base upward, providing a scaffold for epithelial cell migration.
Do not confuse normal granulation tissue with signs of infection. Purulent drainage, increased warmth, swelling, and erythema suggest wound infection, not healthy proliferation. Also, mature scar formation is a feature of the later remodeling phase.
