23 Jul Preparation method and application of bionic composite nanofiber stent material
Abstract
The invention relates to a preparation method and application of a bionic composite nanofiber stent material. The material comprises an artificial nanofiber scaffold material and an extracellular matrix material derived from cells. According to the composite nanofiber material disclosed by the invention, advantages of no toxicity, degradability and the like of the traditional L-polylactic acid biomedical material are reserved and mechanical properties such as the flexibility and the tensile strength of the stent material are also improved; since the extracellular matrix has high conservative property among different species, decellularized extracellular matrix stent has advantages of low immunogenicity, excellent biocompatibility and the like; and the mesenchymal stem cells that are goingto be implanted into the body of a patient and are amplified can be inoculated and thus a tissue engineering prosthesis stent for being implanted into the human body to replace defective tissues is formed after proper culturing.
