  • Ready to use biodegradable and biocompatible cell-based nerve conduit for nerve injury and a method of preparation thereof
    Patent number: 11957815
    Abstract: An artificial tissue construct for nerve repair and regeneration includes a biocompatible and biodegradable nerve guidance matrix comprising a plurality of biopolymers that include chitosan, gelatin, collagen and hyaluronic acid. A cross-linker includes glutaraldehyde. The nerve guidance matrix is formed as a three-dimensional scaffold polyelectrolyte complex (PEC). A subconfluent and grown monolayer of at least one of human mesenchymal stem cells, mesenchymal stem cells, differentiated Schwann cells and neuronal cells is on the biocompatible and biodegradable nerve guidance matrix for direct implantation or delivery. A method of making the artificial tissue construct is disclosed.
