Project description:A549 and MDA-MB-231 cells were cultured in 2D and Matrigel based 3D culture for 4 days. Total RNA was extracted using Trizol. RNA-SEQ was carried out to profile the gene expression in both culture conditions.
Project description:Preclinical cancer drug discovery efforts have employed two-dimensional (2D)-cell-based assay models, which fail to forecast in vivo efficacy and contribute to a lower success rates of clinical approval. Three-dimensional (3D) cell culture models are recently expected to bridge the gap between 2D and in vivo models. We have developed novel 3D culture method that improves the growth of spheroid-forming cancer cells under anchorage-independent condition by leveraging a feature of FP001. Gene microarrays were used to observe the global gene expression in A549 cells cultured with normal adhesion plate (2D, control) or with low adhesion plate (+FP001) and identified distinct classes of up or down-regulated genes. A549 cells were cultured for 5 days in three different conditions as follows. (1) Normal attachment plates with normal medium (as control), (2) low-attachment plates with normal medium, (3) low-attachment plates with FP001 containing medium. Each sample was collected three times.

We have developed novel 3D culture method that improves the growth of spheroid-forming cancer cells under anchorage-independent condition by leveraging a feature of FP001. Gene microarrays were used to observe the global gene expression in A549 cells cultured in multi-well plate with or without FP001 and identified distinct classes of up or down-regulated genes. A549 cells were cultured for 5 days in normal attachment plate with normal medium (as control) or normal attachment plate with FP001 containing medium. Each sample was collected three times.
Project description:In order to gain insight into epithelial morphogenesis and the influence of culture geometry on gene expression patterns, Madin Darby Canine Kidney (MDCK) epithelial cells where grown in 2-dimensional (2D) culture or 3-dimensional (3D) culture . MDCK cells cultured in 2D were plated atop a pre-solidified type I collagen gel. Cells cultured under these conditions grew as flat monolayer sheets. In 3D culture, cells are embedded within type I collagen gel. Cells grown under these conditions form large spherical cysts with hollow central lumens. We anticipate, therefore, that these results provide insight into the mechanisms that regulate epithelial cystogenesis.
Project description:Gene expression of a 3D model for the treatment of EGFR mutated lung tumors (HCC827 cell line, sensitive to gefitinib, and A549 cells, insensitive to gefitinib) was analysed and compared to the same treatment effects in the cell lines when cultured under 2D conditions.
