Oxidative and heat stress gene changes in hypertrophic scar fibroblasts stimulated with interleukin-1beta.

Introduction: Cutaneous wounds that involve loss of tissue heal through a complex process of generating granulation tissue to initially cover the wound, followed by epithelialization, and contraction. Normal healing requires a delicate balance between cellular, matrix, and vascularity build up and breakdown. Defects in the regulation of this balance can alter normal scar formation through fibroblastic hyperproliferation, which is characteristic of hypertrophic scar formation.
