摘要

诱导性多能干细胞(iPSC)在许多方面,如再生医学和药物筛选方面,是理想的细胞来源,其开发前景广阔。但是,目前还没有一种有效的大规模生产系统来确保诱导性多能干细胞的稳定供应。本文综述了近年来为了实现诱导性多能干细胞的稳定生产所采取的方法。本文首先讨论了诱导性多能干细胞培养过程中需要控制的因素,如养分供应、废物清除和氧气供应。然后,介绍了基于黏附、悬浮和支架的诱导性多能干细胞培养系统的最新研究。本文还讨论了细胞培养阶段之后进行的过程,如灌装和冻存过程,由于细胞悬浮液在超低温保存培养基中存活率降低,所以其生产规模受到了限制。最后,我们总结了实现诱导性多能干细胞稳定生产的可能性,并强调了仍有待克服的局限性。本文表明为了获得最佳且稳定的大规模生产诱导性多能干细胞系统,运用多学科研究手段对研究影响细胞生长和质量的复杂因素是至关重要的。
