- W2009192011 abstract "Background: Physiological healing in acute wounds generally occurs by granulation from the wound base and by migration of epithelium from the wound edges toward the center of the wound in a uniform, concentric fashion. The Wound Healing Cooperative Group (WHCG) compared this phenomenon in acute wounds treated with standard care versus acute wounds pharmacologically stimulated with growth factor therapy. Methods: With informed consent, 20 normal healthy volunteers underwent four 6 mm biopsies of the flexor surface of both forearms. The biopsy sites were randomly assigned to a control arm (daily bacitracin) or to one of three treatment arms: i) rhPDGF-BB 0.01% gel Q.D., ii) rhPDGF-BB Q.O.D., iii) daily rhPDGF-BB (Q.D. × 7 days followed by bacitracin alone daily). Wound morphology was carefully examined and photographed daily until complete healing was achieved. Results: There were distinct differences in the morphological pattern of healing seen between control wounds and growth factor-stimulated wounds. Acute wounds treated with bacitracin tended to heal in circumferential fashion, as predicted. Growth factor-stimulated wounds, by contrast, exhibited accentuated angiogenesis (granulation), with non-uniform epithelial islands streaming into the wound. Conclusion: This pilot study suggests that rhPDGF-BB influences acute wound healing by promoting accelerated granulation and epithelialization. Accelerated healing is manifest by different healing morphologies. The biological basis for these differences requires further histological and molecular analyses.
