23 Jul Preparation method of nerve defect repair material of vessel basilar membrane imitating structure
Abstract
The invention discloses a preparation method of a nerve defect repair material of a vessel basilar membrane imitating structure, and belongs to the fields of a tissue engineering technology and a biological material. On the basis of the arrangement of peripheral nerve collagen fibers and the structural characteristics of a nerve fiber vessel basilar membrane, the peripheral nerve defect repair material of the vessel basilar membrane imitating structure is prepared mainly from a high polymer material and a natural material in accordance with an electro-spinning technology and a pore-forming technology. Different from other nerve conduits, the cross section of the material is represented as a porous micro-tubular structure and fiber arrangement on the tube wall is highly oriented in a direction consistent with the moving direction of microtubule. The specific surface area of the tube wall of the material is significantly improved, and the structure of the microtubule is similar to that of the nerve fiber vessel basilar membrane; a plurality of nerve growth promoting substances can be added; and the tissue engineering peripheral nerve defect repair material is good in biocompatibility and convenient for the nerve fibers to grow in the direction of principal axis of the repair material, and the repair material has an application prospect.
