Abstract

The invention provides a preparation method of a conductive tissue engineering material carrying traditional Chinese medicine monomers and neural stem cells for treating spinal cord injury, which is characterized by comprising the following specific steps: S1, preparing electroactive hydrogel; s2, preparing a high dose of ligustrazine-electroactive hydrogel; s3, preparing electroactive hydrogel carrying ligustrazine and neural stem cells; the electroactive hydrogel is co-cultured with embryonic neural stem cells by using a cell transplantation technology, so that the embryonic neural stem cells are loaded on the electroactive hydrogel, and a novel composite material with excellent physicochemical properties such as conductivity, histocompatibility, degradability and spinal cord matching property is constructed; the purity, the cell activity and the cell proliferation speed of the embryonic neural stem cells can be remarkably improved; the differentiation of the embryonic neural stem cells can be inhibited; and the pluripotent differentiation potential of the embryonic neural stem cells can be maintained.

Description

technical field [0001] The invention relates to the technical field of biological materials, in particular to a preparation method of a conductive tissue engineering material carrying traditional Chinese medicine monomers and neural stem cells for treating spinal cord injury. Background technique [0002] The difficulty of nerve repair after spinal cord injury has always been a difficult problem to solve. Conductive tissue engineering materials show good application prospects in the field of nerve repair and regeneration. However, the role of electrical tissue engineering materials is limited to improving the local electrical microenvironment of the spinal cord, which is beneficial to the repair of electrical conduction pathways. [0003] Currently, the most widely used conductive tissue engineering materials are electroactive hydrogels, which can fill the spinal cord cavity, provide an electrical microenvironment, and serve as a good drug-carrying platform. However, it al...
