Fig. 1From: Gene and miRNA expression signature of Lewis lung carcinoma LLC1 cells in extracellular matrix enriched microenvironmentCell morphology differences of LLC1 cells grown under 2D or lr-ECM 3D growth conditions. Prior to imaging cells were grown under 2D (upper panel) and lr-ECM 3D (lower panel) cell culture conditions for 48 h. Representative phase contrast (a) and confocal laser scanning microscopy images (b) of cells under 2D and 3D growing conditions. F-actin was stained with AlexaFluor 633 Phaloidin (red). Nuclei were counterstained with DAPI (blue). Bars 100 μm (upper panel) and 30 μm (lower panel)Back to article page
