Repair of abdominal wall defect with engineered scaffold using tenocytes seeded porcine small intestinal submucosa in rats
摘要
Abstract
Objective To investigate the biomechanicai properties of the engineered scaffold using tenocytes seeded small intestinal submucosa (SIS) in abdominal wall defect. Methods Abdominal wall defect was repaired using engineered scaffold in rat modes. The rats were sacrificed after 4 weeks and the sample tissues were analyzed by gross observation, histological method and mechanical testing. Results All rats had no abdominal dehiscence or hernia. The engineered scaffold caused slight adhesion with organs. HE and Masson staining proved the junction between SIS and surrounding tissue had more new vessels. The muscle grew into the engineered scaffold. The mechanical strength of the engineered scaffold was much more than the abdominal wall muscles, which could provide sufficient mechanical strength. Conclusions Engineered scaffold repairing abdominal wall defect is a feasible and effective method.关键词
