title: Suitability of fetal tissues from spontaneous abortions and from ectopic pregnancies for transplantation. Human Fetal Tissue Working Group.
abstract: OBJECTIVE
  To assess the potential availability and utility of fetal tissues obtained from spontaneous abortions and from ectopic pregnancies for human transplantation therapy.
  
  
  METHODS
  Tissue collection and analysis by personnel skilled in tissue banking.
  
  
  METHODS
  Procurement programs in five tissue banks located in diverse geographical areas that are funded by the National Institutes of Health.
  
  
  METHODS
  All women entering obstetric clinics during 1993 who consented to participate in the study.
  
  
  METHODS
  None.
  
  
  METHODS
  Evaluation of the products of conception by standard developmental, histological, microbiological, and cytogenetic criteria.
  
  
  RESULTS
  From 22,235 obstetric admissions, 1250 spontaneously aborted embryos and 247 products of ectopic pregnancies were obtained. Of these, seven embryos (0.5%) were potentially useful for human transplantation therapy.
  
  
  CONCLUSIONS
  Fetal tissues from spontaneous abortions and from ectopic pregnancies are quite limited as feasible sources for human transplantation therapy.
