N2 - Lung adenosquamous carcinomas, cell line H125, with an expression of human epidermal growth factor receptor 1 (HER1), were cultured on two scaffolds of poly(ϵ-caprolactone) produced through electrospinning, one with a nanometric size and the other with a micrometric size. Cytotoxicity, adhesion and proliferation assays demonstrated the non-cytotoxicity of the scaffolds and the capacity of the cells to grow on them. Tumorlike morphology of cells, HER1 expression and the initial formation of invadopodia were detected through fluorescence microscopy. In the nanometric scaffolds, spheroid formation of cancerous cells was observed. Cells cultured in nanometric scaffolds presented higher resistance to cetuximab than those cultured in micrometric ones and also than cells of two-dimensional cultures. This work demonstrated the potentialities of poly(ϵ-caprolactone) scaffolds for lung adenosquamous carcinoma cultures and is an initial step for further studies on the growth of cancer cell spheroids on electrospun nanofibers.
