23 Jul Peripheral nervous graft of tissue engineering
Abstract
The utility model discloses a peripheral nervous graft of tissue engineering. The utility model provides a surgery graft with wider applicability and better quality to repair the nerve defect. The peripheral nervous graft of tissue engineering of the utility model comprises a support used for connecting the two break ends of the nerve and a seed cell with the function of accelerating the nerve to regenerate, and the seed cells are attached on the support, and the composite body with nerve imitating three-dimensional structure and bioactivity is formed. The support is a variant nerve without cells, and the seed cells are the class schwann cells formed by the adult stem cell induced in vitro. The utility model is the real peripheral nervous graft of tissue engineering of the genuine meaning, and the utility model provides a biochemical imitation path for the regenerated nerve fiber to pass through the nerve defect area, and the seed cells in the peripheral nervous graft have the promotion effect on the nerve regeneration. Thus, the longer distance nerve defect can be repaired by the utility model. The nerve repairing effect is greatly improved, and the clinical application of the utility model is wider.
