23 Jul Tissue engineering 3D stent based on bean curd as well as preparation method and application thereof
Abstract
The invention discloses a tissue engineering 3D stent based on bean curd as well as a preparation method and application thereof. The preparation method comprises the following steps: firstly pre-freezing the bean curd, and then carrying out freeze-drying treatment to obtain the tissue engineering 3D stent based on bean curd. A loose and porous structure is formed in the tissue engineering 3D stent prepared by taking the bean curd as the raw material; various and obvious pore channels are communicated with each other; the requirement of the cell growth on the stent material structure is met; after the prepared 3D stent is simply treated, the 3D stent can be directly applied to the tissue engineering field; the cells achieve effective adhesion, growth and proliferation on the surface of the3D stent; the 3D stent has an obvious promotion effect on the growth of the cells; meanwhile, the product is stable in structure, high in biocompatibility and excellent in mechanical property; in addition, the tissue engineering 3D stent is simple to operate and high in repeatability; the condition is easy to implement; the prepared product is reliable in performance and has broad application prospects in the tissue engineering field.
