Abstract
The composite bone tissue engineering rack material includes collagen, hydroxyapatite, chondroitin sulfate and bone morphogenetic protein; and has 3D porous structure of aperture 50-150 microns. The ratio between collagen and hydroxyapatite is 1 to 1-10, and the chondroitin sulfate is compounded with other components via cross-linking. The material may be constituted into tissue engineering artificial bone based on tissue engineering principle. The present invention has excellent physical, chemical and biological performance, is excellent bone tissue engineering rack material, and may be used in repairing bone defect caused by different reasons clinically.
