The membrane permeating antibacterial peptide, PR-39, previously found only in the intestine, was purified from wound fluid and shown to possess syndecan-1 and syndecan-4 inductive activity specifically in mesenchymal cells. This is a newly recognized function that defines peptide containing syndecan-inducing activity, and that are known as synducins. Therefore a molecule with both antimicrobial and synducin activities is deposited in wounds where it can simultaneously reduce infection and influence the action of growth factors, matrix components, and other cellular effectors involved in wound repair. Synducins, including PR-39, and derivatives thereof, is therefore useful in the modulation of wound healing, as well as other disorders involving mesenchymal cells and cell surface molecular interaction, including metastatic disease, angiogenesis, restenosis, stasis or decubitis ulcers, and prevention of keloids.
