Abstract
Background
The manufacturing of T cell therapies aims to achieve high yields of product with potent phenotypes. We have developed a novel bioreactor, bioreactor with expandable culture area—dual chamber (BECA-D), which has previously demonstrated functionality for scaled T cell manufacturing.
Methods and Results
Methods and Results: In this study, incorporation of a stirring mechanism into the double-chamber bioreactor design was tested to homogenize the media components between the two chambers. In addition to the improved media homogenization, the stirring culture was observed to have higher yield and enrichment of central memory T cells, a T cell subpopulation that has been associated with improved therapeutic efficacy compared with a static control. BECA-D with a stirring mechanism was evaluated for its performance in culturing T cells in comparison with a static control, BECA-D, and an industry benchmark, G-Rex10 (Wilson Wolf Manufacturing). BECA-D with a stirring mechanism was able to preferentially promote the enrichment of central memory T cells compared with the static cultures, indicative of the effect of the stirring mechanism.
Conclusion
By achieving high T cell yields with a favorable subpopulation profile, the mechanical method of incorporating stirring into a double-chamber bioreactor such as BECA-D carries great potential as a useful research and manufacturing tool to support advanced T-cell therapy manufacturing.
背景:制造 T 细胞疗法的目的是获得具有强效表型的高产量产品。我们开发了一种新型生物反应器--带可扩展培养区-双室(BECA-D)的生物反应器,该生物反应器先前已证明具有规模化制造 T 细胞的功能:方法与结果:方法与结果:在这项研究中,对双室生物反应器设计中的搅拌机制进行了测试,以均匀两个室之间的培养基成分。与静态对照组相比,除了提高培养基均质化效果外,还观察到搅拌培养具有更高的中心记忆 T 细胞产量和富集度,而中心记忆 T 细胞是一种与提高疗效相关的 T 细胞亚群。与静态对照 BECA-D 和行业基准 G-Rex10(Wilson Wolf Manufacturing 公司)相比,我们对带有搅拌机制的 BECA-D 培养 T 细胞的性能进行了评估。与静态培养相比,带有搅拌机制的 BECA-D 能够优先促进中枢记忆 T 细胞的富集,这表明了搅拌机制的作用:通过实现具有良好亚群特征的高 T 细胞产量,在双室生物反应器(如 BECA-D)中加入搅拌的机械方法极有可能成为支持先进 T 细胞疗法制造的有用研究和制造工具。
