模块化多功能3D细胞共培养系统

在3D共培养新标准

3D CoSeedis?是一种新型的wu支架3D细胞共培养系统。它由te的基于琼脂糖的基质组成，其中包含一系列圆锥形微孔。这种布置的te殊且专有的形貌允许以高度可重复且一致的方式形成球形和非球形细胞聚集体。阵列内的圆锥形微孔可j确确定聚集体的体积，从而确定细胞的生长。此外，3D CoSeedis?系统的模块化组成允许与实际测试细胞物理分离的饲养细胞共培养（远距离共培养）。因此，此设置负责定义条件下的协议标准化。

High-Throughput / High-Content Screening Applications

3D CoSeedis? is an ideally suited production tool to grow spheroidal 3D cell constructs in large scale, particularly for the use in HTS/HCS applications. With the various formats (2x2, 1x1, 0.5x0.5), it is possible to grow up to 1’200, 5’280, and 16’320 spheroids per plate, respectively.

The major advantages for subsequent HTS/HCS are:

3D CoSeedis? matrix consists of agarose => biologically inert carrier matrix
Substantial reduction of cell culture work (50’000 3D constructs/day ® 3 – 10 3D CoSeedis? plates).
> 5’000 3D constructs per 6-well plate; >16’000 per 24-well plate.
Highly reproducible and homogeneous 3D cell aggregates across matrix and plates.
Increased screening efficiency through highly homogenous 384-well plates seeded with 1 to several 3D constructs / well.
Long-term studies possible: up to 70 days in culture.
Dual and sequential treatments possible over extended
period of time with lots of up to 900 cell aggregates.
Fully validated for a wide range of tumour 3D aggregates.
Modular set-up (e.g. distance co-cultures) significantly extends
the range of testable cells in 3D including primary cells and iPS.
Fully validated read-outs:
- Growth monitoring
- Viability
- Cytotoxicity
- Histology: paraffin and frozen
- Colony forming assay
