Role of cytokines in healing chronic skin wounds.
In the chronic wound, the normal cascade of inflammation, granulation and reconstruction phases of healing is interrupted. Cytokines are now known to orchestrate different biochemical mediators resulting in the restoration of the healing phases. Growth factors may play a significant role in stimulating wound repair by stimulating growth and proliferation. Since growth factors stimulate a variety of functions depending on cell type and wound stage and since wound-healing defects may occur at any phase of healing, a mixed combination of growth factors would be predicted to be more effective than a single factor. Factors that may modulate the action of growth factors include electrical stimulation, weight bearing, debriding and ischemia.
