23 Jul Tissue engineering nerve graft with suspension fiber scaffold and preparation method thereof
Abstract
The invention discloses a tissue engineering nerve graft with a suspension fiber scaffold. The nerve graft comprises a conduit and tube fiber scaffolds. The nerve graft is characterized in that a plurality of suspensions are arranged on each fiber scaffold along the fiber length direction, and are connected with the inner wall of the conduit; and the fiber scaffolds are distributed and suspended in the conduit by virtue of the suspensions. By utilizing bio-printing technology, built-in microfilaments of a tissue engineering nerve graft can be stably and uniformly distributed in the conduit by utilizing the supporting force of the suspensions, and each fiber scaffold has an independent space to guarantee that nerve cells can directionally grow along the fiber scaffolds and cannot have error bridging, so that the success rate of operations can be greatly improved.
