Gene expression perturbation in vitro—A growing case for three-dimensional (3D) culture systems

Birgersdotter, Anna, Sandberg, Rickard, Ernberg, Ingemar·2005·Seminars in Cancer Biology

Abstract

Cells grown in vitro are dramatically perturbed by their new microenvironment. Analyses of genome-wide gene expression levels offer a first glance at which genes and pathways are affected in cell lines as compared to their tissues of origins. We have summarized available gene expression data and review how cell lines adapt to in vitro environments, to what degree they express markers of their tissues of origins and discuss how cells grown in three-dimensional (3D) cultures may have more physiological interactions with neighbouring cells and extracellular matrix. We will also discuss the interplay between malignant cells and stroma present in tumours but lacking in cell lines and how these differences might affect gene expression comparisons of cell lines to tumours. A model simulating impact of stromal cells on gene expression profiles is presented. Understanding the transcriptomes of cells grown in 2D and 3D cultures and how they compare to those of in vivo cells are important for improving cell line model systems and for the reconstituting of tissues in vitro.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • 2D cell culture tests sometimes provide misleading and nonpredictive data for in vivo responses.

    “As a result, 2D cell culture tests sometimes provide misleading and nonpredictive data for in vivo responses. 1-3”
  • When cells are placed back into an in vivo environment or grown in a reconstituted basement membrane resembling ECM, differences in morphology, proliferation, and gene/protein expression are largely restored.

    “Although cells lose many of their native in vivo characteristics after being removed from the primary tumor and cultured in a 2D system, when the cells are placed back into an in vivo environment ( i.e. , an animal model) or grown in a reconstituted basement membrane that resembles the ECM, these differences in morphology, proliferation, and gene/ protein expression are largely restored. 1,35”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
