Project description:To characterize cells cultured in 3D culture system using NanoCulture plates (NCPs) (Scivax) and in 2D culture, we examined gene expression in HT-29 cells on day 1 or day 7 on NCPs or 2D monolayer culture, using DNA microarrays. From our study, tumour cells grown on NCPs were morphologically different from cells in 2D monolayers, and the cells on NCPs actively migrated and aggregated to form multicellular spheroids (MCSs). To characterize this cell migration and intercellular adhesion, we compared gene expression in HT-29 cells on day 1 on NCPs and 2D monolayer culture using DNA microarrays. We could not find any significant difference in gene expression related to cell migration or cell-cell adhesion between cells grown on NCPs and as 2D monolayers on day 1, showing that cells on NCPs migrated and aggregated without any changes in gene expression (3D Day1 vs 2D Day1 2Fold change.xls). We next characterized mature 3D MCSs on NanoCulture plates, by comparing the gene expression profile of MCSs on day 7 and day 1 (3D Day7 vs 3D Day 1 2Fold change.xls). On day 7, we found a statistically significant increase in the expression of genes related to multicellular organization, intercellular signalling and the response to hypoxia. DNA microarray analysis also showed that the expression of genes that have been reported to be target genes for the transcription factor hypoxia-inducible factor 1 (HIF-1) (Ke, Q. & Costa, M. Hypoxia-inducible factor-1 (HIF-1). Mol Pharmacol 70, 1469-1480 (2006); Semenza, G.L. Defining the role of hypoxia-inducible factor 1 in cancer biology and therapeutics. Oncogene 29, 625-634.) was increased on day 7. When compared day 7 with 2D culture cells, the same tendency was observed (3D Day7 vs 2D Day 7 2Fold change.xls). HT-29 cells were maintained routinely as 2D monolayers in a humidified atmosphere of 5% CO2 in air at 37 °C in the growth medium recommended by suppliers. Exponentially growing cells were used in experiments, after trypsinization to detach them from the plates. Viable cells were counted using trypan blue dye-exclusion. For experiments, cells were seeded in 96-well plates at 1×10^4 cells/100 ul of NanoCulture Medium-M (Scivax) in either NCPs (Scivax), or in polystyrene plates for 2D monolayers, for 1 day or 7 days. Cells were collected and used for RNA extraction and DNA microarray analysis.

Project description:The traditional method for studying cancer in vitro is to grow immortalized cancer cells in two-dimensional (2D) monolayers on plastic. However, many cellular features are impaired in these unnatural conditions and big alterations in gene expression in comparison to tumors have been reported. Three-dimensional (3D) cell culture models have become increasingly popular and are suggested to be better models than 2D monolayers due to improved cell-to-cell contacts and structures that resemble in vivo architecture. The aim of this study was to compare gene expression patterns of MCF7 breast cancer cells when grown as xenografts, in 2D, in polyHEMA coated anchorage independent 3D models and in Matrigel on-top 3D cell culture models. Surprisingly small variations in gene expression patterns were observed between the models indicating that 3D and xenograft are not always that different from 2D cell cultures.

Gene expression analysis of MCF7 breast cancer cells cultured as xenografts for 43 days, in two dimensional cultures for seven days (2D7d), in polyHEMA three dimensional cell culture models for four and seven days (PH7d and PH7d), and in Matrigel three dimensional cultures for four and seven days (MG4d and MG7d). Two biological replicates was included for each sample.

Project description:The objective of this study was to use RNAseq to determine which gene change in expression when LKR10 cells are grown in monolayers (2D) or methylcellulose on ultra low attachment plates (3D), which prevents attachment of cells to the plate and promotes formation of 3D sphere-like clusters. A secondary objective was to determine whether knockdown of Ankrd35 altered gene expression of specific genes in 2D or 3D.

Project description:Human bone marrow mesenchymal stromal cells (MSCs) are conventionally cultured as adherent monolayers on tissue culture plastic. MSCs can also be cultured as 3D cell aggregates (spheroids). Optimised 3D conditions (60,000 MSCs cultured as a spheroid for 5 days) inhibited MSC proliferation and induced cell shrinkage in the absence of cell death. Primary human MSCs isolated from 2 donors were cultured under both monolayer (2D MSCs) and optimised 3D (3D MSCs) conditions. High quality RNA was isolated from all samples, and global gene expression analysis was performed in duplicate (using Agilent SurePrint G3 Human Gene Expression 8x60K v2 Microarrays) to identify gene expression changes in 3D compared to 2D MSC cultures.

Project description:In order to determine genes that are differentially expressed during angiogenesis, Human Umbilical Vein Endothelial Cells (HUVEC) were cultured as 3D cultures undergoing tubulogenesis in a 3D fibrin matrix, or cultured as monolayers on top of a 3D fibrin matrix. RNA was then collected, reverse transcribed to cDNA and hybridized to glass slide oligo arrays containing 19k human genes. Differentially expressed genes in HUVECs undergoing tubulogenesis were then determined by comparing 2D to 3D culture samples.

Project description:Analysis of 2D (transwell) and 3D (collagen type I) cultured MDCK cells and HGF (a MAPK activator). Traditional 2D cultures are fast and inexpensive but do no mimic natural niche/cell environment as well as the more laborious and costly 3D-cultures. 3D cultures, arguably, are better models for the study of developmental processes, such as tubulogenesis. Epithelial organs (such as kidney) develop via tubulogenesis, a process, at least in part, regulated by MAPK signaling. Therefore, 2D and 3D cells also treated with HGF plus MAPK inhibitors. Results provide insights into differential response to HGF-induced tubulogenesis depending on cell culture conditions (2D vs. 3D). 29 samples total: 2D and 3D control (untreated) in quadruplicate, respectively; 2D and 3D + HGF in quadruplicate, respectively; 2D + HGF + PD-98059 in quadruplicate; 3D + HGF + PD-98059 in triplicate; 2D + HGF + U0126 in triplicate; and 3D + HGF + U0126 in triplicate.
