Organoids are three-dimensional cell cultures that more accurately model cell behavior, organ function, and pathology than traditional two-dimensional cell culture. Organoid News was launched in 2020 to help scientists stay up-to-date with this revolutionary new research system. Use Organoid News to stay current with the latest applications and discoveries using organoids, as well as new reviews, jobs, news, and upcoming events.

The Microfluidic Environment Reveals a Hidden Role of Self-Organizing Extracellular Matrix in Hepatic Commitment and Organoid Formation of hiPSCs

Hepatic progenitor cells either derived in microfluidics or exposed to exogenous ECM stimuli showed a significantly higher potential of forming hepatic organoids that could be rapidly expanded for several passages and further differentiated into functional hepatocytes.

Patient-Derived Glioblastoma Stem cells transfer mitochondria through Tunneling Nanotubes in Tumor Organoids

Both glioblastoma stem cells, grown in classical 2D culture and in 3D-tumor organoids, formed functional tunneling nanotubes which allowed mitochondria transfer.

Shared Extracellular Vesicle miRNA Profiles of Matched Ductal Pancreatic Adenocarcinoma Organoids and Blood Plasma Samples Show the Power of Organoid Technology

Researchers showed that the miRNA cargo of extracellular vesicles (EVs) from pancreatic ductal adenocarcinoma organoids largely differs among patients. However, they detected a common set of EV miRNAs that were present in matched organoids and blood plasma samples of individual patients.
