    Abstract

    GSK3ß Inhibitor CHIR 99021 Modulates Cerebral Organoid Development through Dose-Dependent Regulation of Apoptosis, Proliferation, Differentiation and Migration

    Scientists demonstrated that while low dose of GSK3β inhibitor CHIR 99021 increases organoid size, higher dose actually reduced organoid size; with the highest dose arresting organoid growth.

    Abstract

    Stem Cell Neurodevelopmental Solutions for Restorative Treatments of the Human Trunk and Spine

    New models of posterior embryo development identify neuromesodermal progenitors as a major bifurcation point in generating the spinal cord and somites and is leading to production of cell types with the full range of axial identities critical for repair of trunk and spine disorders. This is coupled with organoid technologies including assembloids, circuitoids, and gastruloids.
