中文摘要：

目的 对脱细胞胶原基质双层材料和骨髓间充质干细胞（BMSCs）间的生物相容性进行研究.方法 将BMSCs与脱细胞胶原基质双层材料共培养作为实验组,单独培养的BMSCs为对照组,对BMSCs的生长和增殖情况进行研究,扫描电镜下观察细胞在材料上的贴附生长情况,并采用CCK-8法测定细胞活性.结果 扫描电镜结果显示BMSCs在脱细胞胶原基质双层材料上生长良好.CCK-8法测得的BMSCs与脱细胞胶原基质双层材料共培养的生长曲线显示,实验组与对照组间差异无统计学意义（P＞0.05）.结论 脱细胞胶原基质双层材料具有较好的生物相容性,这为脱细胞胶原基质组织工程支架双层材料下阶段在体内动物中的应用提供了科学依据.

英文摘要：

Objective To study the biocompatibility of bone marrow mesenchymal stem cells （BMSCs） on acellular collagen matrix double-layer material.Methods BMSCs with acellular collagen matrix double-layer material were trained as experimental group,while separately cultured BMSCs as control group.The growth and proliferation of BMSCs on acellular collagen matrix double-layer material were investigated.Scanning electron microscope was used to observe the adherence of cells,and cell vitality was detected by CCK-8 method.Results The acellular collagen matrix double-layer material did not influence the growth and proliferation of BMSCs.The difference between the growth curves of experimental group and control group was not significant （P〉0.05）.Conclusions The acellular collagen matrix double-layer material has acceptable biocompatibility.This research provides a scientific basis for the application of this composite material.
