Abstract

Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal malignancies, partly due to the dense desmoplasia and a lack of suitable model systems to study. In the present work, we developed a 3D heterospecies spheroid model to study the microenvironmental interactions between tumor cells and stellate cells which can also be employed to test therapeutic regimens. We set up monospheroids and heterospheroids made up from murine pancreatic stellate cells (mPSCs) and human PDAC cells (Panc1), which allowed for direct isolation of mRNA from a mixed cell population followed by an in silico separation of the RNA-seq reads. Global transcript level changes for cells in heterospheroids versus monospheroids were calculated, followed by gene set enrichment analysis and molecular subtype analysis. We observed an apparent shift of Panc1 from the classical to the squamous/basal-like phenotype upon co-culture with mPSCs. Moreover, mPSCs acquired a different cancer-associated fibroblast-related phenotype upon co-culture with Panc1. We analyzed the tumor cell-specific chemosensitivities towards gemcitabine, paclitaxel and SN38 and compared these to published pharmacotranscriptomic signatures. In conclusion, our heterospecies spheroid model reflected key aspects of PDAC and facilitated the study of intercellular interactions between tumor and stroma while additionally proving to be a good model for studying therapeutic responses.

  • Compared with 2D cell cultures, 3D spheroids more closely resemble PDAC tumours in structure and increased chemoresistance, providing a more accurate drug response.

    “compared to 2D cell cultures, 3D spheroids more closely resemble PDAC tumours in terms of their structure and their increased chemoresistance, providing a more accurate drug response [38]”

    From Pyrvinium Pamoate Alone and With Gemcitabine Exhibits Anti‐Pancreatic Cancer Activity in <scp>2D</scp> and <scp>3D</scp> Cell Culture Models (2024) · cites this paper as [38]

    The Introduction says 3D cultures more closely resemble in vivo conditions than monolayers and that spheroids show increased chemoresistance. The Conclusion says the PDAC co-culture model recapitulates key tumour features and is suitable for drug testing. The paper does not establish that its drug responses are more accurate than those from 2D cultures. (LLM, conf=0.83)

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.
