title: Acute excisional wounds treated with a tissue-engineered skin (Apligraf).
abstract: BACKGROUND
  Tissue-engineered products are usually composed of living cells and their supporting matrices that have been grown in vitro, using a combination of engineering and life sciences principles. Apligraf is a bilayered product composed of neonatal-derived dermal fibroblasts and keratinocytes, and Type I bovine collagen.
  
  
  OBJECTIVE
  To evaluate in a prospective, multicentered open study, the effects of tissue therapy with a tissue-engineered skin (Apligraf) with partial or full-thickness excisional wounds.
  
  
  METHODS
  One hundred and seven patients participated in this study. The tissue-engineered skin was applied once, immediately after excisional surgery, usually for skin cancer, and patients were followed for up to one year.
  
  
  RESULTS
  The safety results were impressive, with no clinical or laboratory evidence of rejection. Clinically, graft persistence was good to excellent in 77 of 105 (73.3%) of patients at one week, falling to 56.6% and 53.6% at two weeks and one month respectively.
  
  
  CONCLUSIONS
  To date, this is the largest experience with a tissue-engineered skin product in acute wounds, and this study suggests that tissue therapy may be safe and useful.
