Abstract

Clinical implementation of tumor organoids for personalized medicine requires that pure tumor organoids can be reliably established. Here, we present our experience with organoid cultures from >70 non-small cell lung cancer (NSCLC) samples. We systematically evaluate several methods to identify tumor purity of organoids established from intrapulmonary tumors. Eighty percent of organoids from intrapulmonary lesions have a normal copy number profile, suggesting overgrowth by normal airway organoids (AOs). This is further supported by the failure to detect mutations found in the original tumor in organoids. Histomorphology alone is insufficient to determine tumor purity, but when combined with p63 immunostaining, tumor and normal AOs can be distinguished. Taking into account overgrowth by normal AOs, the establishment rate of pure NSCLC organoids is 17%. Therefore, current methods are insufficient to establish pure NSCLC organoids from intrapulmonary lesions. We discourage their use unless steps are taken to prevent overgrowth by normal AOs.

  • Genetic drift can occur in organoids cultured for extended time, which can affect their reliability as models for functional and drug discovery studies.

    “Overall, these studies showed that genetic drift can occur in organoids cultured for extended time, influencing their reliability as models for functional and drug discovery studies133.”

    From Organoids (2022) · cites this paper as [133]

    The 'Selection for Tumor Cells' section (page not available in our copy) says normal organoids may eventually dominate mixed cultures and that such cultures complicate interpretation of drug screens. This supports a concern about model reliability during culture, but the paper does not establish genetic drift in organoid cells after extended culture or its effect on functional studies.

  1. Data and code availability Deposition of DNA sequencing data in publicly availably repositories is limited and regulated by the informed consent signed by patients participating in the study. Requests for sequencing and copy number data can be made by emailing the Institutional Review Board of the Netherlands Cancer Institute (IRB@nki.nl). Any other requests can be directed to the Lead author, Emile E. Voest (e.voest@nki.nl). EXPERIMENTAL MODEL AND SUBJECT DETAILS Patient tissue Tissue was obtained from NSCLC patients undergoing surgery or receiving a 18G core needle tumor biopsy. Tumor tissue and macroscopically inconspicuous normal lung tissue (distant from the tumor site) were obtained for organoid culture. Tumor and normal tissue from the same patient share the same prefix (e.g., ITO54-T and ITO54-H, respectively). Written informed consent was obtained from all patients, and the study was approved by the Medical Ethical Committee of the Netherlands Cancer Institute -Antoni van Leeuwenhoek hospital (study NL48824.031.14). Tissue was stored in Ad-DF+++ (Advanced DMEM/F12 (GIBCO), with 1% Ultraglut- amine I (GIBCO), 1% penicillin/streptomycin (GIBCO), 1% HEPES (GIBCO)) supplemented with 2% Primocin (Invivogen) at 4 C and processed for organoid culture within 24 hours. Organoids ITO22-T, ITO31-T1, ITO34-T, ITO41-T, ITO42-T, and ITO62-T have been described in Dijkstra et al., 2018 previously as (NSCLC-1 through NSCLC-6, respectively). Organoid establishment and culture Organoids were established and cultured as described in Sachs et al., 2019. Briefly, tumor or normal lung tissue was dissociated into small pieces using scalpels and digested for 30-60 minutes using 1.5 mg/mL collagenase II (Sigma-Aldrich), 2 mg/mL dispase type II (GIBCO), 10 mM Y-27632 (Sigma-Aldrich) and 1:500 Primocin in PBS. After digestion, cells were isolated by repeated resuspension and washed three times in PBS. Cells were plated in ice cold 10 mg/mL Geltrex (GIBCO) in 6-well culture plates. After letting Geltrex drops solidify for 15 minutes at 37 C, cells were overlaid with lung organoid medium, composed of Ad-DF+++ supplemented with 10% Noggin conditioned medium, 10% R-spondin-1 conditioned medium, 1x B27 supplement (GIBCO), 1.25

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.
