摘要:

背景:相关实验表明Bio-Gide胶原膜与细胞有良好的生物相容性,但有关与其复合培养干细胞成骨分化能力的报道少见。
目的:观察Bio-Gide胶原膜对骨髓间充质干细胞增殖及成骨分化的影响。
方法:全骨髓贴壁法体外分离培养兔骨髓间充质干细胞,将第3代兔骨髓间充质干细胞分别接种于覆盖Bio-Gide胶原膜的培养板(实验组)与单纯培养板(对照组)培养。于培养1,4,7,14 d利用CCK-8试剂盒检测细胞增殖;成骨分化诱导培养1,4,7,14 d收集细胞培养液上清,检测细胞碱性磷酸酶活性。
结果与结论:两组细胞数量均随着培养时间的增加而不断增加,对照组培养7 d细胞数量明显多于实验组(P < 0.05),其他时间点组间比较差异无显著性意义。两组细胞碱性磷酸酶活性均随着培养时间的增加而不断增加,实验组成骨诱导14 d细胞碱性磷酸酶活性高于对照组(P < 0.05),其他时间点组间比较差异无显著性意义。表明Bio-Gide胶原膜可促进兔骨髓间充质干细胞的增殖及成骨分化。

Abstract:

BACKGROUND: Bio-Gide collagen membranes show a good biocompatibility with stem cells. But the research on the osteogenetic differentiation of bone marrow mesenchymal stem cells cultured on the Bio-Gide collagen membranes is rarely reported.
OBJECTIVE: To observe the effect of Bio-Gide collagen membranes on the proliferation and the osteogenetic differentiation of bone marrow mesenchymal stem cells.
METHODS: Bone marrow mesenchymal stem cells from rabbits were isolated and cultured by using the whole bone marrow adherence method in vitro. Passage 3 bone marrow mesenchymal stem cells were selected and seeded on the Bio-Gide collagen membrane pretreated petri dish (experimental group) and simple petri dish (control group). The proliferation of bone marrow mesenchymal stem cells was detected by Cell Counting Kit-8 at 1, 4, 7, 14 days. The supernatant of the cells cultured in osteogenic differentiation medium were collected to detect the activity of alkaline phosphatase at 1, 4, 7, 14 days.
RESULTS AND CONCLUSION: The number of bone marrow mesenchymal stem cells in the two groups was increased with the increasing time, and the control group had more cells than the experimental group at 7 days  (P < 0.05). There was no significant difference between the two groups at other time points. The alkaline phosphatase activity was increased with the increasing culture time, and the experimental group had a higher activity than the control group at 14 days (P < 0.05). There was no significant difference between the two groups at other time points. Experimental findings indicate that Bio-Gide collagen membranes can promote the proliferation and the osteogenetic differentiation of bone marrow mesenchymal stem cells.
