  scaffold
Biomimetic strengthening polylactide scaffold materials for bone tissue engineering
      
In this paper, a new polylactide (PLA)-based scaffold composite by biomimetic synthesis was designed.
      
The compressive strength of the composite is higher than that of the PLA scaffold.
      
Using the osteoblast culture technique, we detected cell behaviors on the biomaterial in vitro by SEM, and the cell affinity of the composite was found to be higher than that of the PLA scaffold.
      
The biomimetic three-dimensional porous composite can serve as a kind of excellent scaffold material for bone tissue engineering because of its microstructure and properties.

目的:通过卵磷脂和多聚赖氨酸分别和共同包埋以聚乳酸固定成形的聚羟基乙酸支架与软骨细胞体外培养,来观察其亲水性和对细胞吸附力的改变以及对细胞功能的影响。方法:将软骨细胞种于上述支架体外培养,通过倒置显微镜及扫描电镜观察支架的亲水性、对细胞的吸附力及基质产生情况。结果:支架以卵磷脂包埋后细胞悬液易浸入到支架内;以多聚赖氨酸包埋后细胞易吸附在支架纤维表面;以卵磷脂和多聚赖氨酸共同包埋后细胞均匀分布于支架纤维之间及吸附在支架纤维表面,且基质产生旺盛。结论:卵磷脂具有增强支架亲水性作用;而多聚赖氨酸除增加支架对细胞的吸附力外,还具有促进细胞功能的作用。以卵磷脂和多聚赖氨酸共同包埋支架可能是组织工程技术中较理想的支架之一。

砄bjective:To investigate the feasibility of using cancellous bone matrix as scaffolds for bone tissue engineering. Methods: The marrow stromal cells of newborn New Zealand rabbits were cultivated and induced in vitro and then seeded into alginate- cancellous bone matrix to form cancellous bone matrix-alginate-marrow stromal osteoblasts composites. The composites were implanted subcutaneously in nude mice. The cancellous bone matrix alone was implanted as control. The osteogenesis was assessed by histological...

砄bjective:To investigate the feasibility of using cancellous bone matrix as scaffolds for bone tissue engineering. Methods: The marrow stromal cells of newborn New Zealand rabbits were cultivated and induced in vitro and then seeded into alginate- cancellous bone matrix to form cancellous bone matrix-alginate-marrow stromal osteoblasts composites. The composites were implanted subcutaneously in nude mice. The cancellous bone matrix alone was implanted as control. The osteogenesis was assessed by histological and roentgenographic analysis. Results: The osteogenesis in the composites was better than that in the cancellous bone matrix. In the composites, both fibrous and cartilaginous osteogenesis were found and the former appeared more obvious. In the control, only slight cartilaginous osteogenesis was found. Conclusion: The cancellous bone matrix can be used as a scaffold material for bone tissue engineering.

目的:观察松质骨基质- 骨髓基质成骨细胞复合移植皮下成骨作用,以探索松质骨基质作为骨组织工程支架材料的可行性。方法:新生兔骨髓细胞体外培养、诱导后,接种于藻酸盐/松质骨基质中,形成松质骨基质/藻酸盐/骨髓基质成骨细胞复合物,并植入裸鼠背部皮下,对照组单纯植入松质骨基质。植入4、8 周后行 X线摄片和组织学检查,观察骨形成情况。结果:松质骨基质/骨髓基质成骨细胞复合物皮下成骨效果明显优于松质骨基质。前者兼有纤维成骨和软骨成骨,以纤维成骨为主;后者仅见少量软骨成骨。结论:松质骨基质可以作为一种良好的骨组织工程支架材料。

Results:The cells were removed...

Objective:To investigate a method to remove cellular components from bovine pericardial tissue,resulting a scaffold for tissue engineering of heart valve or cardiovascular patch. Methods:A detergent and enzyme extraction was practiced in this study.HE staining was performed to confirm the removal of cells and Von Gieson staining,to show the integrity of collagen and elastin.The changes in tissue shrinkage temperature,and mechanical properties were also studied. Results:The cells were removed effectively from bovine pericardial tissue,while the collagen and elastin were kept intact.The mechanical properties remained unaltered.Only the tissue shrinkage temperature dropped insignificantly. Conclusion:The research work demonstrated an effective procedure to remove cells from bovine pericardial tissue while kept its mechanical properties.The acellular matrix needs to be further evaluated biochemically and ultrastructurally.This approach may eventually lead to the engineering of tissue heart valves repopulated with patients' own cells.
