23 Jul Tissue engineering cartilage composite stent and preparation method
Abstract
The invention relates to a tissue engineering cartilage composite stent and a preparation method. The composite stent comprises a stent body of a pore structure and hydrogel; the stent body is prepared from a medical macromolecule material by rapid prototyping; the hydrogel is compounded in the pore structure of the stent body and the surface of the stent body, and the hydrogel is mixed with bone marrow mesenchymal stem cells. By compounding the stent body prepared from the hydrogel and the medical macromolecule material, the prepared tissue engineering cartilage composite stent not only has good mechanical strength of the medical macromolecule material, but also provides a good microenvironment for material interchange of the bone marrow mesenchymal stem cells in the stent and on the surface of the stent and differentiation to chondrocytes by keeping a high water content through the hydrogel.
