When keloid (N = 2 and normal (N = 12) fibroblast cell strains were evaluated, expression of HOXA7, HOXA9 and HOXC8 was significantly lower in keloid versus normal fibroblasts. However, HOX gene expression was lower in fibroblasts from more anterior versus posterior body sites. When keloid and normal cells from similar body sites were compared, differential HOX expression was not observed. To investigate the phenotypic relevance of HOX expression, HOXA9 was overexpressed in keloid and normal fibroblasts. HOXA9 overexpression did not a
