title: Pathological scarring: strategic interventions.
abstract: Aberrant cutaneous scar formation is a substantial cause of postoperative morbidity. There is at present no clear consensus on the best way to prevent or treat such scarring, although recently there has been considerable progress in developing an understanding of the mechanisms of tissue repair and scarring. We carried out a literature review using Medline to establish the current understanding of the key events occurring during tissue repair and to identify potential causes of scarring. We now review the key events during tissue repair and the pathogenesis of fibroproliferative disease. Tissue repair is achieved through a multistranded, elegantly coordinated process within which the balance between synthesis and breakdown of matrix is upset during fibrotic disease. Scars form because the signals directing tissue repair are not correctly terminated, and while the initiation and propagation of repair is well understood the signals that direct its cessation have yet to be elucidated.
