Several injectable materials have been used as osteogenic bone substitutes. However, none has gained universal acceptance. This study was performed to investigate whether or not chitosan-alginate gel/mesenchymal stem cells/bone morphogenetic protein-2 composites are potentially injectable materials for new bone formation.
The composites were injected into the subcutaneous space on the dorsum of nude mice to investigate new bone tissue formation. The composites were examined histologically over a 12-week period.
The composites injected into the mouse were able to stimulate new bone formation, which was trabecular in type.
This study showed that chitosan-alginate gel/MSCs/BMP-2 composites could become clinically useful injectable materials to generate new bone.
几种可注射材料已被用作成骨性骨替代物。然而,没有一种获得普遍认可。进行本研究以调查壳聚糖 - 海藻酸盐凝胶/间充质干细胞/骨形态发生蛋白 - 2复合材料是否为用于新骨形成的潜在可注射材料。
将复合材料注射到裸鼠背部的皮下空间,以研究新骨组织的形成。在12周的时间内对复合材料进行组织学检查。
注射到小鼠体内的复合材料能够刺激新骨形成,新骨为小梁骨类型。
本研究表明壳聚糖 - 海藻酸盐凝胶/间充质干细胞/骨形态发生蛋白 - 2复合材料可成为临床上用于生成新骨的有用可注射材料。
