Soft culture plates for pleased cells
Soft culture plates for pleased cells
In vitro cell culture and cell-based assay are recognized as important contributors to persistent failures to translate promising preclinical drug candidates into clinical success. A cell culture device should not only allow the cell survival and growth, but allows the cells to express the same characteristics that they have in vivo. And in vivo, cells are parts of “soft” organs where they receive and interpret biochemical signals but also physicals signals, which they are sensitive to 1.
Our organs are one billion times softer than plastic, and they are mechanically textured.

Cells sense and respond to matrix stiffness, an effect named mechano-sensing. The mechanical properties of the micro-environment deeply impact cell behaviour, including transcriptional regulation3, protein synthesis4, endocytosis5, and malignant progression6. The failures of standard culture dishes to maintain the phenotype of many primary cells, or by appearing as wrong predictors to translate promising in vitro results into in vivo clinical and industrial models and clinical success support the evidence than these standard tools have now reached their limits. Then, now,
let’s reinvent cell culture…
…with using soft, mechano-mimetic culture plates!

Cell&Soft soft bottoms are made of polyacrylamide, bound to a 150µm thin glass coverslip.
Consistent mechanical properties
The hydrogel is photo-polymerized, to ensure uniform rigidity and reproducibility.
Consistent surface chemistry
The culture plates are pre-coated with adhesive molecules. Cell&Soft guarantees that the surface density of the coating is independent of the rigidity.
Surface coating of the polyacrylamide hydrogel.
a) The human truncated recombinant vitronectin (VTN-N) is covalently grafted to the surface and does not penetrate into the hydrogel. Horizontal bar: 50µm. Vertical bar: 10µm.
b) The surface density of the VTN-N is independent of the rigidity of the hydrogel.
Meeting high quality standards
Cell&Soft culture plates are manufactured in dust free, ISO7, clean room environment.
Lot number traceability
A lot number is attributed to every product to ensure traceability. Series can be booked.
Cell&Soft provides uniformly soft or rigidity-textured cell culture plates, with an adhesive coating.
The culture plates offer mechanical features as close as possible to those found in vivo in animal or human tissues.

Textured rigidity: the MecaChips
The MecaChips are culture dishes with several rigidities on the same dish. Two designs are presently available, with adhesive coating:
Millimeter scaled rigidity steps Micron wide rigidity stripes
0,5 – 2,6 – 4,5 – 9 – 15 kPa
