    Carbon Nanotubes Promote the Development of Intestinal Organoids through Regulating Extracellular Matrix Viscoelasticity and Intracellular Energy Metabolism

    The authors investigated the profitable effect of carbon nanotubes (CNTs) with a different graphene layer and surface modification on the 3D model of intestinal organoids and demonstrated that CNTs promoted the development of intestinal organoids over time.

    Abstract

    Parkinson’s Disease Phenotypes in Patient Neuronal Cultures and Brain Organoids Improved by 2-Hydroxypropyl-β-Cyclodextrin Treatment

    Investigators evaluated the difference between controls’ and phosphatase and tensin homolog-induced putative kinase 1 (PINK1) patients’ derived neurons in their transition from neuroepithelial stem cells to neurons, allowing them to identify potential pathways to target with repurposed compounds.

    Abstract

    Epithelial Argininosuccinate Synthetase Is Dispensable for Intestinal Regeneration and Tumorigenesis

    Researchers investigated the function of argininosuccinate synthetase (ASS1) in the gut epithelium during tissue regeneration and tumorigenesis, using intestinal epithelial conditional Ass1 knockout mice and organoids, and tissue specimens from colorectal cancer patients.
