| abstract |
The present invention relates to a method for manufacturing a porous three-dimensional fiber structure using an electrohydrodynamics-based 3D printing process, and to an injection agent for tissue grafting comprising the fiber structure produced by the method, and a fiber structure that has been produced in two dimensions through the present invention Can be produced as a three-dimensional structure, and because the three-dimensional fabricated structure has a void structure, cells can be cultured in three dimensions, thereby promoting tissue differentiation. In addition, the fabricated 3D fibrous structure has high elasticity and can be injected into a needle, so it can be implanted into damaged tissue more easily. Since it is composed of micro/nano fibers, a small amount of material is used compared to conventional fibrous structures. Can be used to fabricate a structure. Therefore, the present invention is expected to be useful in the field of tissue regeneration and transplantation. |
