Abstract

Tumors are not merely masses of neoplastic cells but complex tissues composed of cellular and noncellular elements. This review provides recent data on the main components of a dynamic system, such as carcinoma associated fibroblasts that change the extracellular matrix (ECM) topology, induce stemness and promote metastasis-initiating cells. Altered production and characteristics of collagen, hyaluronan and other ECM proteins induce increased matrix stiffness. Stiffness along with tumor growth-induced solid stress and increased interstitial fluid pressure contribute to tumor progression and therapy resistance. Second, the role of immune cells, cytokines and chemokines is outlined. We discuss other noncellular characteristics of the tumor microenvironment such as hypoxia and extracellular pH in relation to neoangiogenesis. Overall, full understanding of the events driving the interactions between tumor cells and their environment is of crucial importance in overcoming treatment resistance and improving patient outcome.

  • Fibroblasts respond to chemotactic signals such as TGF-β, PDGF, and CXCL12, which are differentially distributed within tumors and drive directed migration toward tumor cores.

    “fibroblasts respond to a variety of chemotactic signals such as TGF-β, PDGF, and CXCL12, which are differentially distributed within tumors and further drive their directed migration toward tumor cores [286].”

    From Modeling Tumor Microenvironment Complexity In Vitro: Spheroids as Physiologically Relevant Tumor Models and Strategies for Their Analysis (2025) · cites this paper as [286]

    The Background section on fibroblasts says TGF-β affects fibroblasts, and the section on matrix topology describes directional cell migration guided by physical cues. But the paper does not say that TGF-β, PDGF, and CXCL12 form differential distributions that direct fibroblasts toward tumor cores; its discussion of CXCL12 concerns attraction of immune cells, not fibroblasts.

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.
