title: An organ-culture for in vitro evaluation of fetal membrane healing capacity.
abstract: OBJECTIVE
  We aimed to set up an organ culture of human amniochorion to evaluate fetal membrane repair capacity following surgical trauma.
  
  
  METHODS
  Fetal membranes were collected from four patients, during elective caesarean section at term. Explants were traumatised at the centre and cultured on collagen support material for a total of 12 days. Viability was assessed by light microscopy and proliferation by detection of 5-Bromo-2' deoxy-Uridine (BrdU) incorporation and immunohistochemistry. Wound healing capacity was assessed trough photographic documentation every 2 days.
  
  
  RESULTS
  Cultures showed good survival for 12 days. Increased cellularity, survival and proliferations were observed at the borders of the cultures in contrast to the central trauma site. During the 12 days observation period, no significant closure of the membrane defect could be demonstrated.
  
  
  CONCLUSIONS
  This organ culture system represents a new model for the study of human fetal membrane repair. Despite good survival and localised proliferation, no obvious closure of a surgically created defect was observed in the described culture conditions.
