PART 1: Communication via direct cell-to-cell contacts vs. communication via soluble factors (distance co-culturing)

Revolutionize predictive disease modeling.
A brief introduction to highly efficient and predictive disease modelling with 3D CoSeedis™.

Many diseases elude current in vitro testing methods and consequently make the identification of effective new treatments cumbersome if not impossible. Likewise, in vitro diagnostics are often difficult or lead to ambiguous results.
With 3D CoSeedis™, abc biopply is now introducing a revolutionary 3D cell culture platform that enables to address complex disease models at an unprecedented depth. Yet, the 3D CoSeedis™ system is simple, robust and user friendly in its set-up, highly reproducible and reliable.

For the first time, 3D organoids/spheroids are now:

  • Accessible in complex cell-to-cell and
  • Organ-to-organ communication systems
  • Available in high quantities
  • Highly homogeneous and uniform for reliable read-outs

3D CoSeedis™ therefore:

  • Optimises the statistical biological relevance of test results
  • Makes mimicking of a variety of different cell communication models possible
  • Opens a new era of disease modelling
Communication via direct cell-to-cell contacts
vs. communication via soluble factors
(distance co-culturing)

Feeder cells are often used
  • To support test cells of interest during their aggregation phase
  • To receive assessable 3D structures, particularly with cells that do normally not form 3-dimensional constructs in vitro
Contact: feeder cells are intermingled with test cells to form 3D aggregates
Distance: feeder cells are separated from test cells by 3D CoSeedis™ chip.
Chip matrix permeable to all relevant factors.


Using regular technologies, such as hanging drop or liquid overlay, the only way to make use of feeders is to mix them with test cells.

Mixed cultures of test- and feeder cells result in:
  • Intermingled and inseparable 3D constructs consisting of test cells and feeders
  • Biased results due to mixed response signals to test compound

Why does 3D CoSeedis™ pose such a revolutionary new way to do 3D cell culture?

3D CoSeedis™ circumvents the drawbacks of regular 3D cultures by introducing the distance co-culture approach to use feeder cells:
  • An elegant and easy way to use feeders physically separated from test cells
  • It allows supporting factors from the feeder cells to still influence the test cells
  • Feeders can be left behind after aggregation by simply lifting off the 3D CoSeedis™ chip including the test cell 3D cultures
  • Subsequently, 3D cultures can be grown further in a fresh culture plate in the absence of feeder cells

One last thing...

... the distance co-culture setup of 3D CoSeedis™ can do a lot more:
  • It also allows to mimic cell-to-cell communication in general
  • It distinguishes between membrane-bound signal transduction (contact co-culture) and communication pathways mediated via soluble factors (distance co-culture)
  • And it can be used to mimic complex, multi-cellular disease models….. more about that in Part II of this exciting story
