Case-Matched Analysis of Fibroblast Function in Patients with Keloids

Focus Area

Keloids represent aggressive and prolonged fibroblast responses to cutaneous trauma with significant disfigurement, and in many instances functional impairment. Many treatments have been employed with unacceptably high rates of recurrence. Recent advances in studies of systemic markers of disease and the role of circulating progenitor cells in other inflammatory conditions have demonstrated a common pathway for regional trafficking of fibroblasts that could be inhibited in order to prevent aberrant postoperative wound healing and keloid recurrence. Our goal is to determine if patients who form keloids demonstrate a higher proportion of circulating fibroblast precursors in peripheral blood samples, and if keloid specimens contain a significant concentration of surface markers responsible for local trafficking of this precursor cell. This phenomenon has been demonstrated in similar patient populations within our collaborating laboratory at UV A (R. Strieter). We hypothesize that peripheral blood samples taken before, during and after elective keloid excision will demonstrate a higher concentration of circulating fibroblast progenitor cells (CD451184), compared to case controls without keloids undergoing minor elective surgery. We anticipate that keloid specimens will demonstrate significant expression of fibroblast trafficking ligand CXCLI2, and hypoxic inducing factor (HIF-I), a marker of hypoxic insult present in states of prolonged inflammation and angiogenesis. The ability to detect the local upregulation of this pathway, and to inhibit its aggressive function will allow for proper peri-operative counseling before elective surgery and provide a novel, specific treatment to help decrease keloid recurrence.
