静/动态培养模式对CIK细胞体外扩增与代谢特性的影响及其机制
发布时间:2021-11-18 14:46
过继性免疫细胞疗法是一种非常有前景的肿瘤疾病治疗手段。细胞因子诱导的杀伤细胞(Cytokine induced killer,CIK)是过继性免疫细胞疗法中常用的效应细胞之一,基于CIK细胞的免疫细胞疗法目前在多种肿瘤疾病的临床治疗中取得了积极的成果,具有广阔的应用前景。由于细胞治疗的效果与输注细胞的数量和质量密切相关,因此是否能在短时间内获得足够数量且具有高抗肿瘤活性的CIK细胞是决定该疗法能否取得预期疗效的关键环节之一。目前CIK细胞的体外制备过程通常是采用培养袋进行静态培养,但该培养模式由于混合效果和气液传质能力差,容易使营养物或代谢副产物产生浓度梯度,导致培养环境不均一且难以控制,不仅影响细胞扩增的效果以及所获得CIK细胞的功能,也使得扩增工艺过程难以重复。为解决这一问题,本文尝试建立CIK细胞的动态培养技术,期待通过良好的混合解决培养环境不均一的问题,通过增加物质传递提高营养物的利用效率,从而实现CIK细胞的高效扩增,为将来建立基于生物反应器的CIK细胞或其它免疫效应细胞的高效规模化扩增技术提供技术支撑。本文采用有血清培养体系以脐带血单个核细胞(Cord blood mono...
