Select from the dropdown lists to complete the text.

Tissue ( remodelling, regeneration, renewal, proliferation ): the ECM of ( granulation, epithelial, vascular ) tissue must be degraded to ( remodel, redesign ) tissue in healing. Matrix metalloproteinases (MMPs) are ( enzymes, cytokines, growth factors, caspases ) that each break down one component of this ECM. They mediate long- term scar maturation and degradation, which is why they can look better over time. The action of MMPs is regulated by ( TIMPs, SIMPs, PIMPs, DIMPs ).
