Papillary thyroid cancer (PTC) has been one of the most frequent endocrine malignancies around the world. See also Supplementary Table 5 (20). Our study demonstrates that the newly established PTC organoids may have potential to predict each individual patients response to treatment and support a potential strategy to attenuate tumor aggressiveness in women with ER-specific antagonists. See also Supplementary Figure 3 (20). 12634-010] containing 1% HEPES [N-2-hydroxyethylpiperazine-N-2-ethane sulfonic acid; Gibco, No. We observed both cohesive (dense and solid structures) and discohesive (irregularly shaped structures) organoids within the same culture derived from the same specimen (Fig. 5A and 5B). sharing sensitive information, make sure youre on a federal Time-lapse phase-contrast imaging of the cohesive PTC organoids showed that many organoids seem to be clonally derived (Fig. 100-26), R-spondin-1 (500 ng/mL, Peprotech, No. Xu C, Yuan X, Hou P, Li Z, Wang C, Fang C, Tan Y. The process, from receiving the sample in the research lab, to having a culture in the incubator, in preparation for the organoids to form, takes around 4 hours. B-Raf proto-oncogene, serine/threonine kinase (BRAF), the most frequently mutated gene in PTC (22) and the well-known driver gene associated with the mitogen-activated protein kinase (MAPK) signaling pathway, was mutated in 5 of 8 patients (Fig. While organoid cultures show great potential, they are limited by the time scale of their growth in vitro and the dependence upon commercial matrices, such as Matrigel, which do not allow for manipulations of their composition or mechanical properties. Scale bar, 100 m. PTC, papillary thyroid cancer; NTG, nodular thyroid goiter; Normal, nontumor normal tissue; T, tumor; O, organoid. This site needs JavaScript to work properly. Q Organoid Cultures Derived From Patients With Papillary Thyroid Cancer Summary of organoid establishment, sources and applications. PTC, like many other cancers, also has intratumoral heterogeneity (23, 24). Patient-derived tumor organoid-based high-throughput screening platforms are also widely used for discovering anti-cancer drugs. Drug sensitivity assays of PTC organoids demonstrate patient-specific drug responses, and large correlations with the respective mutational profiles. We indeed found CK19 and galectin-3, the 2 potential biomarkers expressed in differentiated thyroid cancers, to be expressed both in PTC and NTG tissue-organoid pairs, but not in nontumor thyroid tissues. Primary antibodies against cytokeratin 19 (CK19, 1:200, Maixin Biotech, No. Patient-derived cancer organoids provide a better reflection of native tumors and may fill in the gap between drug screening based on traditional 2D cancer cell lines and clinical trials. Patient-derived tumor organoids (PDOs) currently represent important modeling tools in pre-clinical investigation of malignancies. Patient-Derived Organoids of Colorectal Cancer: A Useful Tool for Results from all these studies suggest that ER is the predominant mediator for the E2-induced cell proliferation in organoid lines. 1D).

E2 (No. Cancer organoid co-culture model system: Novel approach to guide Historically, the most universal preclinical models were mouse models and patient-derived cell lines propagated in 2-dimensional (2D) culture. Interestingly, PTC-1_O, PTC-2-I_O, and PTC-4-I_O were sensitive to selumetinib and trametinib, consistent with BRAF mutations present in these samples (see Figs. All data generated or analyzed during this study are included in this published article or in the data repositories listed in References (20). Further studies in co-clinical trials are necessary to determine whether the patient-derived PTC organoids can predict patient response in the clinic. Whole-exome sequencing (WES) libraries were generated using Agilent SureSelect Human All Exon V6 kit (Agilent Technologies) following the manufacturers recommendations and index codes were added to each sample. , Hedayat S, Vatsiou A, et al. Two or 3 random pieces were snap-frozen and stored at 80 C for DNA isolation, 2 random pieces were fixed in formalin for histopathological analysis and immunohistochemistry, and the remaining tissues were dissociated and processed for organoid derivation. A Loss of tumor suppressors PTEN,, Figure 5. 2017070608). Although patient-derived xenografts maintain the genetic and histological characteristics of the original tumors, they are often inefficient, time-consuming, and technically challenging to establish, making it practically impossible to contribute to personalized therapy to a large extent (5). We also observed several drug sensitivities displaying correlations with their mutational profiles in PTC organoid lines.

All stock solutions were diluted to the desired concentrations with prewarmed culture medium before use. Organoid Cultures Derived from Patients with Advanced - ScienceDirect Here, we discuss the applications of patient-derived tumor organoid cultures and the possibilities in using complex immune-organoid cultures to provide preclinical testing platforms for precision cancer immunotherapy. The existence of different cell subclones with different susceptibilities to drugs is a significant cause of treatment failure (34). A, Flow diagram of establishment and characterization of PTC organoids, including the generation of PTC organoid lines from patients undergoing surgery using optimized medium components, as well as the histological characterization, DNA-sequencing, drug screen, and cell proliferation assay on PTC organoids. 5 and Supplementary Fig. Patient-derived organoids have been suggested as alternative in vitro models that maintain the key features of parental tumors and can potentially be used to select anticancer drugs for individual patients. Similarly, SB202190 was essential for culturing PTC organoid lines in our present study. It was a pleasant surprise to find that the intratumor heterogeneity in human PTCs was also reflected in their derived organoids. 4E).
