iPSC-derived Cancer Organoids Recapitulate Genomic and Phenotypic Alterations of c-met-mutated Hereditary Kidney Cancer

Hereditary cancers with cancer-predisposing mutations represent unique models of human oncogenesis as a driving oncogenic event is present in germline, exposing the healthy member of a family to the occurrence of cancer. The study of the secondary events in a tissue-specific manner is now possible by the induced pluripotent stem cell (iPSC) technology offering the possibility to generate an unlimited source of cells that can be induced to differentiate towards a tissue at risk of malignant transformation. We report here for the first time, the generation of a c-met-mutated iPSC lines from the somatic cells of a patient with type 1 papillary renal cell carcinoma (PRCC). We demonstrate the feasibility of kidney differentiation with iPSC-derived organoids expressing markers of kidney progenitors with presence of tight junctions and brush borders in tubular structures at transmission electron microscopy. Importantly, c-met-mutated kidney organoids expressed PRCC markers both in vitro and in vivo in NSG mice. Gene expression profiling of c-met-mutated iPSC-derived organoid structures showed striking molecular similarities with signatures found in a large cohort of PRCC patient samples and identified 11 common genes. Among these, BHL...Continue Reading

Single-Cell RNA Sequencing: Kidney and Organoids

Single-cell RNA sequencing of the adult human kidney transcriptome can provide molecular information about cell-specific responses to environmental variables and disease states. This information can provide a dataset to benchmark human kidney organoids. Discover the latest research on adult kidney organoids at single cell resolution here.

BioRxiv & MedRxiv Preprints

BioRxiv and MedRxiv are the preprint servers for biology and health sciences respectively, operated by Cold Spring Harbor Laboratory. Here are the latest preprint articles (which are not peer-reviewed) from BioRxiv and MedRxiv.

Brain Organoids in Disease Modeling

Brain organoids are three-dimensional cell culture models derived from human pluripotent stem cells. Since they resemble the embryonic brain, they can be used to help study brain biology, early brain development, and brain diseases.
