Efficient Use of Patient-Derived Organoids as a Preclinical Model for Gynecologic Tumors

Abstract

Objective The relevance of patient-derived cancer cells has been recently increasing, particularly in terms of drug discovery and precision medicine. Whereas Matrigel-based organoid culture is a promising technique that enables infinite proliferation of cells from many types of organs in a physiological condition, its validity in gynecologic tumors remains to be established. To address this issue, we aimed at developing an efficient method for organoid culture of both ovarian and endometrial tumors.Methods We conducted 3D culture of 21 gynecologic tumors following our original and modified protocol for Matrigel bilayer organoid culture. We investigated whether propagated organoids retained various features of the original tumors by histopathological examination and targeted genome sequencing.Results We customized the protocol we previously optimized for murine normal and cancer tissues, so as to circumvent the digestion-resistant nature inherent to gynecologic tumors. Indeed, this modified protocol improved the success rate from 45 to 90%, for robust propagation of organoids from tumors with various stages and subtypes. Finally, 14 patient-derived organoids were established. The recovered organoids were enriched for cancer cells that retained many aspects of the original tumors, including histological features, mutation profiles, and intra-tumoral heterogeneity. A subset of the expanded organoids could develop xenografts in immunodeficient mice, potentially paving the way to drug screening in vivo. Drug response assay in vitro for paclitaxel and cisplatin was feasible using organoid-derived spheroids.Conclusions We showed that patient-derived organoids closely resembled the original gynecologic tumors, and thereby would serve as a promising resource for preclinical studies.

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.
