Three-dimensional porous polyurethane scaffold for repairing central nervous system injury and preparation method |
| abstract |
The present invention provides a three-dimensional porous polyurethane scaffold for repairing central nervous system injury, the scaffold comprises three-dimensional porous polyurethane, and the three-dimensional porous polyurethane has a compression modulus of 0.001-10.0 MPa and a pore diameter of 10-200 microns. The present invention also provides a method for preparing the three-dimensional porous polyurethane scaffold. The three-dimensional porous polyurethane scaffold of the present invention has an efficient central nervous system repair function without additionally implanting functional cells or factors, and can partially restore the original nerve function of the test animal; the preparation method of the three-dimensional porous polyurethane scaffold of the present invention is simple, and has enormous advantages. application prospects. |
