Gene expression profile of mouse Lewis lung carcinoma cell line cultivated in 2-dimensional or 3-dimensional cell culture enriched with laminin rich extracellular matrix proteins.

ABSTRACT: Obvious advantages of 3D cell culture model are the cell morphology better reflecting tissue cell morphology, the formation of zones of i) active proliferation, ii) quiescent viable cell zone and iii) necrotic zone, as well as formation of nutrition, oxygen and drug gradients better reflecting cellular environment in tissue. Nevertheless the 3D cultures are a model still not resembling full complexity of tumor tissue environment in vivo. Few obvious limitations of 3D cell cultures as cancer research model are the lack of vasculature, host immune response and other cell-cell interactions that occur between cancer and stromal cells in tumors. Recognized advantages and limitations of the 3D cell culture models, however do not suggest directly the areas of cancer biology where 3D models could be applied with highest success. Hence detailed analysis at the molecular level of 2D/3D cell cultures and tumors in vivo are needed to unlock the power of 3D cell culture model. In order to elucidate which biological pathways of cancer cells in tumors are best resembled by the 3D cell culture model we have analyzed whole genome gene expression changes in mouse LLC1 cell line when cultured in 2D or laminin rich ECM 3D system.

Gene expression analysis of MCF7 breast cancer cells cultured as xenografts, in two dimensional cultures, in polyHEMA anchorage independent three dimansional cell culture models and in Matrigel three dimensional cultures.

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.

Expression data of two human cancer cell lines cultivated in 2-dimensional (2D) vs. 3-dimensional (3D) cell culture

Project description:3D cultivation of cells lead to changes in morphology of the cells. This is likely to explain the higher radioresistance of cells growing in 3D compared to cells growing in 2D cell culture. Whole genome gene expression is performed to determine genes involved in changes of cell moroholgy and radioresistance. Keywords: comparison of 2D vs. 3D cell culture RNA of cells was isolated four days after growing in the two different cell culture systems

Madin-Darby Canine Kidney (MDCK) cells grown in 2-dimensional and 3-dimensional type I collagen culture.

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. Cells grown in the 2D or 3D geometries were collected from digested type I collagen gels on day 8. The 2D MDCK cells were treated as the control condition and there gene expression patterns were compared to those of 3D grown cells, which served as the experimental condition.

Gene expression analysis in TGFbeta/TNFalpha treated A549 spheroid cultures

Project description:TGFbeta/TNFalpha treated spheroid A549 cultures are a model of the epithelial-mesenchymal transition (EMT). These experiments capture the changes in global gene expression that result from cells being induced to undergo EMT (3D control vs 3D treated), but also the differences in gene expression when A549 is grown in spheroid cultures (2D control vs 3D untreated). EMT is efficiently induced only in the spheroid culture model. A total of 8 samples are analyzed, corresponding to 4 conditions (2D control, 2D treated, 3D control, 3D treated) and 2 biological replicates.

Gene expression profile of Skov3 cells cultured with DMSO (Control) or GA-017 in 3D condition

Project description:3D cell culture models are recognized for representing the physiological microenvironment and exhibiting higher concordance with in vivo conditions, when compared to a conventional 2D cell culture model. However, cells grown in 3D cultures are likely to exhibit slower growth than those in 2D cultures. We found that addition of a novel small molecule named GA-017 to culture media promotes the cell proliferation particularly under 3D conditions. Gene microarrays were used to observe the global gene expression in Skov3 cells cultured under 3D condition with DMSO or GA-017 and identified distinct classes of up or down-regulated genes.

Three-dimensional tumor cell growth stimulates autophagic flux and recapitulates chemotherapy resistance

Project description:Current preclinical models in tumor biology are limited in their ability to recapitulate relevant (patho-) physiological processes, including autophagy. Three-dimensional (3D) growth cultures have frequently been proposed to overcome the lack of correlation between two-dimensional (2D) monolayer cell cultures and human tumors in preclinical drug testing. Besides 3D growth, it is also advantageous to simulate shear stress, compound flux and removal of metabolites, e.g. via bioreactor systems, through which culture medium is constantly pumped at a flow rate reflecting physiological conditions. Here, we show that both Staticic 3D growth and 3D growth within a bioreactor system modulate key hallmarks of cancer cells, including proliferation and cell death as well as macroautophagy, a recycling pathway often activated by highly proliferative tumors to cope with metabolic stress. The autophagy-related gene expression profiles of 2D- and 3D-grown cells are substantially different, with the 3D-grown cells exhibiting an expression profile closely resembling the (patho-) physiological Statice of a tumor. Underscoring the importance of this pathway, autophagy-controlling transcription factors, such as TFEB and FOXO3, are upregulated in tumors, and 3D-grown cells have increased expression compared with cells grown in 2D conditions. Three-dimensional cultures depleted of the autophagy mediators BECN1, ATG5 or ATG7 or the transcription factor FOXO3, are more sensitive to cytotoxic treatment. Accordingly, combining cytotoxic treatment with compounds affecting late autophagic flux, such as chloroquine, renders the 3D-grown cells more susceptible to therapy and increases intracellular doxorubicin concentration to the level of 2D-grown cells. Altogether, 3D cultures are a valuable tool to study drug response of tumor cells, as these models recapitulate (patho-) physiologically relevant pathways, such as autophagy.

Bioengineered models of Parkinson’s Disease using Patient-derived Dopaminergic Neurons exhibit distinct Biological Profiles in a 3D Microenvironment

Project description:Background: Three-dimensional (3D) in vitro culture systems using human induced pluripotent stem cells (hiPSCs) represent impactful platforms to model neurodegenerative disease biology in physiologically relevant microenvironments. Though many successful biomaterials-based 3D model systems have been established for other neurogenerative diseases, such as Alzheimer’s Disease, relatively few exist for Parkinson’s Disease (PD) research. Methods: We employed tissue engineering approaches to construct a 3D silk scaffold-based platform for the culture of hiPSC-dopaminergic (DA) neurons derived from healthy individuals and PD patients harboring LRRK2 G2019S or GBA N370S mutations. We then compared results from protein, gene expression and metabolic analyses obtained from two-dimensional (2D) and 3D culture systems. Results: The 3D platform enabled the formation of dense dopamine neuronal network architectures and developed biological profiles both similar and distinct from 2D culture systems in healthy and PD disease lines. 3D PD cultures showed elevated levels of α-synuclein and alterations in purine metabolite profiles. Furthermore, computational network analysis of transcriptome networks nominated several novel molecular interactions occurring in neurons from patients with mutations in LRRK2 and GBA. Conclusion: The brain-like 3D system presented here is a realistic platform to interrogate molecular mechanisms underlying PD biology. The key advantages of silk-based bioengineering technology include long-term culture and the ability to incorporate multiple brain-relevant cell types to parse cell-cell interactions in development, disease, and aging.
