Project description:In Rspondin-based 3D cultures, Lgr5 stem cells from multiple organs form ever-expanding epithelial organoids that retain their tissue identity. We report the establishment of tumor organoid cultures from 20 consecutive colorectal (CRC) patients. For most, organoids were also generated from adjacent normal tissue. The organoids closely resemble the original tumor. The spectrum of genetic changes observed within the 'living biobank' agrees well with previous large-scale mutational analyses of CRC. Gene expression analysis indicates that the major CRC molecular subtypes are represented. Tumor organoids are amenable to robotized, high-throughput drug screens allowing detection of gene-drug associations. As an example, a single organoid culture was exquisitely sensitive to Wnt secretion (porcupine) inhibitors and carried a mutation in the negative Wnt feedback regulator RNF43 (rather than in APC). Organoid technology may fill the gap between cancer genetics and patient trials, complement cell line- and xenograft-based drug studies and allow personalized therapy design. We generated organoids from healthy tissue and coloncarcinoma tissue. The organoids were trypsinized, plated in matrigel and overlaid with medium. After three days, RNA was isolated using Qiagen RNAeasy. Medium conditions are the same for all organoids, irrespective of their origin.

Project description:We validated fifteen models from “living biobank” to provide models that support interrogation of Chromosome Instability and to evaluate novel therapeutics. Single cell RNA-seq was performed on tumour and stromal cells from 4 patients with ovarian cancer to establish gene expression profile differences between the two cell types and also heterogeneity within the tumour population. The samples used were AS38b, AS59, AS74-1, AS79, they are grown in OCMI media supplemented with 5% hyclone serum (AS38, AS59) or 5% FBS (AS74, AS79) in 5% CO2 and 5% O2. At 37C

Project description:Kidney tumours are among the most common solid tumours in children, comprising several distinct subtypes differing in many aspects, including cell-of-origin, genetics, and pathology. Pre-clinical cell models capturing the disease heterogeneity are currently lacking. Here, we describe the first paediatric cancer organoid biobank. It contains tumour and matching normal kidney organoids from over 50 children with different subtypes of kidney cancer, including Wilms tumours, malignant rhabdoid tumours, renal cell carcinomas, and congenital mesoblastic nephromas. The malignant rhabdoid tumour organoids represent the first organoid model for tumours of non-epithelial origin. The tumour organoids retain key properties of native tumours, useful for revealing patient-specific drug vulnerabilities. We further demonstrate that organoid cultures derived from Wilms tumours consist of multiple different cell types, including epithelial, stromal and blastemal-like. Our organoid biobank captures the cellular heterogeneity of paediatric kidney tumours, providing a representative collection of well-characterized models for basic cancer research, drug-screening, and personalized medicine.
