Growth of primary dermal fibroblasts in the Mimetix scaffold
In vitro skin models are in high demand for investigating the potential toxicity of cosmetics and transdermal therapeutic applications. The study presented below takes a step in this direction by enabling a co-culture of the two major human skin cell types.
Primary dermal fibroblasts were cultured on our randomly orientated fibre scaffold and images were taken after 24 hours and 7 days. After 7 days in culture, cells had proliferated extensively to fill the pores within the scaffold.

Primary dermal fibroblast migration was studied by taking a cross-section of the scaffold, showing that cells had migrated through the loose fibrous network to form a 3D structure. Cells were stained with DAPI to indicate the nuclei.

Co-culture of keratinocytes and human dermal fibroblasts
An in vitro model of skin was produced by culturing primary keratinocytes alongside primary dermal fibroblasts in the Mimetix scaffold, indicating that non-woven electrospun scaffolds are a suitable substrate for co-cultures of primary cells.
