摘要 目的:研究应用无动物来源成分培养脐带间充质干细胞的效果。方法:使用由血清替代物、重组酶及无血清细胞冻存液组成的无动物来源成分培养方案培养脐带间充质干细胞。对培养的脐带间充质干细胞进行检测。结果:当脐带组织块贴壁后,其组织边缘开始有间充质干细胞贴壁爬出。对脐带间充质干细胞进行细胞表型检测的结果显示其中CD73分子、CD90分子及CD105分子呈高表达(阳性率≥95%);其中CD11b分子、CD19分子、CD34分子、CD45分子及HLA-DR分子呈低表达(阳性率≤2%),甚至不表达。对脐带间充质干细胞进行细胞诱导分化检测的结果显示其具有成脂、成骨及成软骨的能力。结论:使用无动物来源成分培养脐带间充质干细胞的质量完全满足国际细胞治疗协会提出的评估间充质干细胞质量的最低标准。
