When the barrier is broken, a regulated sequence of biochemical events is set into motion to repair the damage.

As the wound macrophages switches from inflammatory to healing mode, converting granulation tissue from an environment rich in cells to one that consists mainly of collagen. The keratinocytes secrete the proteins that form the new basement membrane. ECM in their way — these factors attract cells involved in the proliferation stage of healing to the area.
