Cellartis DEF-CS 500 iPS无外源3D悬浮培养基

传统的2D培养系统无法支持放大培养（Scale-up）所需细胞数量级别（> 109个细胞/处理）以维持细胞疗法的增长需求。 3D悬浮培养是大规模生产多能细胞的可行经济有效的解决方案。尽管干细胞传统上难以适应悬浮培养，但CellArtis研究人员已经开发出一种培养体系，可以在成分确定、无饲养层和无异源物条件下实现稳定高效的生长并维持多能性。Cellartis DEF-CS 500 iPS无外源3D悬浮培养基与生物反应器系统配套，为创建大量高质量，未分化的起始材料提供了理想的方法。该培养基的配方基于2D培养基Cellartis DEF-CS 500 Xeno-Free Culture Medium，2D培养的细胞可以轻松过渡到3D以实现可靠的放大。

Cellartis DEF-CS 500 Xeno-Free 3D Spheroid Culture Medium

Traditional 2D culture systems simply cannot support the scale-up required (>109 cells/treatment) to sustain the growing demand for cell-based therapies. 3D suspension culture is a viable, cost-effective solution for large-scale production of pluripotent cells. Although stem cells have traditionally been difficult to adapt to suspension culture, our scientists have developed a culture system that allows robust, stable growth and maintenance of pluripotency under defined, feeder-free, and xeno-free conditions. The Cellartis DEF-CS 500 Xeno-Free 3D Spheroid Culture Medium paired with a perfusion bioreactor system provides an ideal method for creating large amounts of high-quality, undifferentiated starting material. The formulation of this medium is based on the 2D medium, Cellartis DEF-CS 500 Xeno-Free Culture Medium, and cells growing in 2D can easily be transitioned to 3D for robust scale-up.
