[Application of collagen composite scaffold in vascular tissue engineering].

OBJECTIVE
To review the application of collagen and biodegradable polymer composite scaffolds in vascular tissue engineering, and describe the multi-layering vascular scaffolds of collagen-based material in recent years.


METHODS
The literature concerning collagen composite scaffold production for scaffold of vascular tissue engineering was extensively reviewed and summarized.


RESULTS
As one of the structural proteins in natural blood vessel, collagen is widely used in vascular tissue engineering because of good biocompatibility, biodegradability, and cell recognition signal. The vascular scaffolds with biological activity and good mechanical properties can be made by collagen-polymer composite materials. In addition, the structure and function of the natural blood vessel can be better simulated by multi-layering vascular scaffolds.


CONCLUSION
Collagen-polymer composite material is the hot spot in the research of vascular scaffolds, and multi-layering vascular scaffolds have a brilliant future.
