Abstract
A bionic nerve graft and a preparation method thereof is provided. The bionic nerve graft includes a helical stent, a nanofiber membrane, guide fibers and hBMSC-ECM. A surface of the helical stent is coated with the nanofiber membrane, the guide fibers and the hBMSC-ECM are placed in a tube cavity of the helical stent, and the raw materials of the helical stent, the nanofiber membrane and the guide fibers are all chitosan. The preparation method includes the following steps: preparing the helical stent by a mold pouring method, coating the surface of the helical stent with the nanofiber membrane by an electrostatic spinning method, preparing the guide fibers by a template method, and filling the guide fibers and the hBMSC-ECM in the helical stent with the surface coated with the nanofiber membrane.
