23 Jul Esophageal tissue constructed by tissue engineering
Abstract
The invention belongs to the field of biomedical engineering and specifically relates to an esophageal tissue constructed by tissue engineering. A tissue-engineered esophagus containing an epithelial layer and a dermal layer is consisted of scaffold materials and seed cells according to the basic principles and methods of tissue engineering. Vascular endothelial cells in the dermal layer directly participate in the establishment of a capillary network, and two revascularization methods are used to quickly communicate the capillary network in the dermal layer with the blood supply channel of a receptor, thus providing blood to the epithelium of the tissue-engineered esophagus. The esophageal tissue of the invention changes a former therapeutic mode of repairing damage by damage, and can be used for simplifying esophagectomy and one-stage reconstruction of digestive tracts, thus reducing medical trauma and benefiting the majority of patients with esophageal diseases.
