Abstract： |
Disclosed is a nervous tissue engineering tubular supporting stand and method for making same, wherein the nervous tissue engineering tubular supporting stand comprises a chitosan pipe wall and biological source filling base material with axial multiple passages, and the method consists of preparing semipermeable chitosan hollow pipe with 1-5mm of inside diameter, pouring large biological molecule solvent such as chitosan, collagen or gelatine, and utilizing special-purpose die arrangement and lyophilization technology. The obtained multiple-pass nerve channel with bionic construction is beneficial for cell adhesion, migration and leading of neuraxon directional growth, and suitable of the renovation and regeneration of nerve damages. |
