Discover the benefits of SpheroSeev: within days your organoid will be bigger and more vital and will survive longer
SpheroSeev can help!
Improve your spheroid, organoid or co-culture model using our spider silk biomimicry technology
SpheroSeev is a recombinant bio-polymer fiber with the strength and elasticity of spider silk, providing mechanical support and ECM-like environment for organoid formation in a consistent and reproducible manner.
Better Viability, Longevity and Functionality

Improve your chances of successful research:
SpheroSeev combines the advantages of scaffold-based and scaffold-free technologies.
SpheroSeev fibers’ nano and micro dimensions are similar to the natural ECM, providing a tissue-like environment for cells.
SpheroSeev fibers have high porosity, enabling better access to oxygen and nutrients, thereby supporting prolonged viability and functionality.
SpheroSeev fibers have extra strength and elasticity, providing mechanical cushioning and protection to individual cells within the organoid.

| Adipose-derived mesenchymal stem cells (MSCs) cultured as spheroid with SpheroSeev demonstrate tissue-like spread morphology and higher viability than spheroid without SpheroSeev. [Green – viable cells, Red – dead cells] | L929 cell line cultured as spheroid with SpheroSeev demonstrates delayed necrotic core formation and higher viability.

| ATP quantification test on primary rat hepatocytes shows that after 40 days spheroids with SpheroSeev have the same viability levels as the control spheroids in their first two weeks of culture. | SpheroSeev increases rat hepatocyte spheroid longevity for over 41 days compared with non-SpheroSeev spheroids, which disintegrate after ~20 days. | Albumin secretion test on primary rat hepatocytes shows that even after 20 days the spheroid with SpheroSeev retains good functionality while the control tissue shows no activity at all. |
| Increased viability of DU145 cancer cell line | SpheroSeev maintains stem cell spheroid differentiation | Better functionality with SpheroSeev |

| ATP quantification test on DU145 spheroids show that ATP level is higher when SpheroSeev concentration is greater. | hMSCs spheroids with and without SpheroSeev were cultured in adipogenic/osteogenic differentiation medium for 19 days
[Stained with oil red and alizarin red respectively] | SpheroSeev rat hepatocyte spheroids have higher basal and induced activity compared with control spheroids. |
Use SpheroSeev to better mimic natural morphology and behavior of cells, increase the productivity of your research, and reduce overall study costs and time
Here’s more of why to use SpheroSeev in your research:
- Easy to use (a 5-minute process)
- Long shelf life and sterile (up to 1 year)
- Maximum flexibility to manipulate the 3D cell culture environment for different needs
- High consistency for reproducible cell-based assays
- Minimal protocol adaption to switch from 2D or currently used 3D
- Compatible with automated handling and imaging equipment
- Does not degrade or undergo alteration over the course of an experimen

I used “SpheroSeev” for primary glioblastoma cell culture. It helps to form nice and stable tumorspheres, which I never achieved before. With other kinds of matrix, my GBM cell always tends to differentiate, but “SpheroSeev” keeps the stemness of the cells. Great product!

“SpheroSeev” 3D matrix really works well. I could find a nice spheroid. Product was used with colorectal cancer cell lines. I had used different matrixes previously from different companies but I should say from my experience that “SpheroSeev” works better than regular spheroid matrix. I like it!
