Balance 2

Co-cultures require a medium that maintains the delicate balance of proliferation and functionality for both cell types

2D Keratinocyte / Fibroblast Co-culture

Standard proliferation media do not deliver well balanced growth of 2 or more cell types in co-culture.

The new CnT-PR-CC co-culture omits the fibroblast inhibitory elements found in keratinocyte media, whilst in parallel providing an environment that also encourages moderate fibroblast growth in balance with the keratinocytes in regular 2D culture.

For 3D co-culture (full thickness skin model), the CnT-PR-FTAL is recommended (see below).

Test samples of CnT-PR-CC are now available for groups wishing to evaluate this product.

FT Model

Full thickness skin model with fully natural dermal ECM, prepared using CnTPR-F followed by CnT-PR-FTAL for air-lift culture.

3D Co-Culture: Full Thickness Skin Models

Traditional methods for preparation of full-thickness skin models depended in the use of collagen I gels for the establishment of the dermal compartment.

This significantly increases complexity, cost and variability.

Using our novel high-ECM culture media, it is now possible to establish full thickness skin models without the use of collagen gels.

The entire dermal matrix is secreted by the fibroblasts, creating a fully natural and complex mix of ECM proteins.

This approch is simpler, faster, and more reproducible. For more details, please visit the features page.

This model was recently featured at the TEDD 3R conference. Please click here to view the conference report.

Primary keratinocytes and fibroblasts that have been tested for the establishment of FT models are also available as a separate Value Pack.

For the full written protocol describing establishing of the FT models, please visit our Protocols Page.

Kits for Full Thickness Skin Models

Would you like the convenience of ordering a kit with everything needed to establish FT skin models in your own lab?

CELLnTEC offers two different options, one including primary keratinocytes and fibroblasts, and one without.


CnT-PR-KM delivers balanced co-culture of keratinocytes and melanocytes.

Finding Balance: Melanocyte / Keratinocyte Co-culture

To successfully co-culture two cell types together requires that both the cell types retain their functionality, whilst in parallel keeping in a good proliferative balance.

Standard keratinocyte media often contain ingredients that inhibit melanocyte growth, or drive immediate differentiation. The net result is that melanocytes often dont survive well in culture with keratinocytes.

CELLnTEC has developed a new medium for keratinocyte-melanocyte co-culture: CnT-PR-KM.

This medium is specifically designed to maintained a balanced co-culture of primary human keratinocytes and melanocytes for a week in culture. It is currently being evaluated by researchers in academia and industry.
