摘要:

目的观察新型生物材料多孔磷酸钙的生物相容性及复合骨髓基质干细胞(BMSCs)异位成骨情况。方法体外培养第2代Beagle犬BMSCs,转染绿色荧光蛋白(GFP)后与多孔磷酸钙(CPC)复合培养,获得最佳复合浓度,倒置和荧光显微镜、扫描电镜下观察BMSCs黏附和生长情况,复合体植入裸鼠皮下8周观察异位成骨。结果BMSCs转染GFP与多孔CPC复合培养1 d,细胞从材料中爬出,形态正常,7 d可见细胞伸出伪足,分泌基质;复合体可异位成骨。结论多孔CPC生物相容性好,是一种较理想的骨组织工程支架材料。

Abstract:

Objective To observe the biocompatibility of new biomaterials porous calcium phosphate(CPC) and ectopic bone formation of CPC with bone marrow stromal cells(BMSCs). Methods The BMSCs were cultured from Beagle dog and combined with the porous CPC with the best concentration after transfect green fluorescent protein (GFP). The adhesion and growth of BMSCs on CPC were observed under inversion, fluorescence and scanning electron microscopy. The ectopic bone formation were observed at the 8th week after CPC and BMSCs were implanted subcutaneously into nude mice. Results When BMSCs with CPC were cultured at the 1st day, cells were climbing out from CPC with normal morphology. At the 7th day cells can be seen protruding pseudopods, secretion of matrix. Bone formation could be seen histomorphologically at the 8th week. Conclusion Porous CPC has good biocompatibility and is an ideal scaffold material for bone tissue engineering.
