23 Jul Bionical compound engineering bone of cell equipment small intestine submucosa
Abstract
The utility model discloses a bionical compound engineering bone of cell equipment small intestine submucosa, its microstructure include SIS collagen fiber skeleton, mineral crystallization and thin extracellular matrix composition, and the SIS collagen fiber skeleton is the reticular fiber structure, and the mineral crystallization is with carefully extracellular matrix composition deposit is on the SIS collagen fiber skeleton, and the mineral crystallization is guideed by 14 cells of MC3T3 -E1 subclone with thin extracellular matrix composition and the secretion obtains. The utility model discloses bionical compound engineering bone has a higher mechanical strength, do, wet state elastic modulus down can reach 350MPa, 100MPa respectively, can provide better tissue and support implanting the internal initial stage, the inside mineral structure of this bionical compound engineering bone and natural bone with distribute very closely, the microstructure who highly is similar to natural bone has, do benefit to after the implantation better by discernment and accelerate the osteanagenesis.
