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.

Manipulating the Tumor Microenvironment in Tumor Organoids Induces Phenotypic Changes and Chemoresistance

Investigators used a tumor organoid model, consisting of hepatic stellate cells embedded in Collagen-1 (Col1) and colorectal cancer cell (HCT-116) spheroids, to determine the relationship between the ECM architecture, cancer cell malignancy, and chemoresistance.

ROCK Inhibitors Beneficially Alter the Spatial Configuration of TGFβ2-Treated 3D Organoids from a Human Trabecular Meshwork (HTM)

TGFβ2 significantly increased the TEER values in 2D cultures, and the ECM expression indicated that the 3D organoids assumed a more densely packed shape.

Dissecting the Non-Neuronal Cell Contribution to Parkinson’s Disease Pathogenesis using Induced Pluripotent Stem Cells

The authors report on recent work using human induced pluripotent stem cell (iPSC) and 3D brain organoid models showing that iPSC technology can be used to recapitulate Parkinson’s disease-relevant disease-associated phenotypes, including protein aggregation, cell death or loss of neurite complexity and deficient autophagic vacuoles clearance and focus on the recent co-culture systems that are revealing new insights into the complex interactions that occur between different brain cell types during neurodegeneration

FAM3D is Essential for Colon Homeostasis and Host Defense against Inflammation Associated Carcinogenesis

Researchers demonstrated that deficiency in Fam3D was associated with impaired integrity of colonic mucosa, increased epithelial hyper-proliferation, reduced anti-microbial peptide production and increased sensitivity to chemically induced colitis associated with high incidence of cancer.

Membrane Tension Gates ERK-Mediated Regulation of Pluripotent Cell Fate

Researchers found that shape change was regulated by a β-catenin-mediated decrease in RhoA activity and subsequent decrease in the plasma membrane tension. Preventing a decrease in membrane tension results in early differentiation defects in ESCs and gastruloids.
