版纳小型猪脱细胞骨基质的抗原检测及力学性状

Antigen Measurement and Biomechanical Characteristics of the Inbred-line Banna Mini-pig Acellular Bone Matrix

制备版纳小型猪脱细胞骨基质,进行组织学和生物力学观察,并进行了异种抗原-αga l表达的检测,结果表明经脱细胞处理后,去除了骨组织的细胞成分,同时消除了抗原性,力学性质上与正常对照无明显差异,可以作为一种合适的骨组织工程支架材料。

In this study, we prepared the acellular bone matrix of the inbred-line Banna mini-pig by using tissue engineering method and evaluated its possible application in bone tissue engineering. Histological analysis, xenoantigen expression and biomechanical measurement were performed on the matrix. HE staining and scanning electron microscopy showed the cellular components were almost removed. Immunohischemical result demonstrated that the xenoantigen, a-gal,was also eliminated. There was no statistically significant difference between the acellular bone matrix group and control group. The acellular bone matrix can provide appropriate space structure and strength for grafts. In conclusion, our data suggest that acellular bone matrix is a new kind of ideal bone scaffold material.
