3D細胞共培養系統-3D CoSeedis，

模塊化多功能3D細胞共培養系統

在3D共培養新標準

3D CoSeedis™是一種新型的無支架3D細胞共培養系統。 它由*的基于瓊脂糖的基質組成，其中包含一系列圓錐形微孔。 這種布置的特殊且專有的形貌允許以高度可重復且一致的方式形成球形和非球形細胞聚集體。 陣列內的圓錐形微孔可確定聚集體的體積，從而確定細胞的生長。 此外，3D CoSeedis™系統的模塊化組成允許與實際測試細胞物理分離的飼養細胞共培養（遠距離共培養）。 因此，此設置負責定義條件下的協議標準化。

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

3D CoSeedis in High-Throughput / High-Content Screening

Research Applications

3D CoSeedis™ has been validated for various applications and according protocols have been developed. The different application notes can be downloaded here or contact us for further information.

Colony Forming Assay

A new approach to the colony forming assay in cancer research. 3D CoSeedis™ simplifies and facilitates the set-up, read-out and analysis of the assay substantially.

For further details you may also refer to the following Whitepaper.

Viability / Cytotoxicity

The application note addresses viability and/or cytotoxicity of 3D cell constructs grown in 3D CoSeedis™. The protocol describes an extension to all existing 3D CoSeedis™ systems and can be implemented easily without further requirements in equipment or appliances.

Cryo-embedding

3D CoSeedis™ offers an easy and elegant way to embed 3D constructs for cryo-sectioning without the need to manipulate individual spheroids. It reduces tricky and cumbersome manipulations and prevents damage or loss of 3D constructs.
