Generation of Spheroids from Human Pluripotent Stem Cells

Source: Shaker, M. R., et al. Robust and Highly Reproducible Generation of Cortical Brain Organoids for Modelling Brain Neuronal Senescence In Vitro. J. Vis. Exp. (2022). This video demonstrates the transformation of human pluripotent stem cells (hPSCs) into spherical brain organoids. By using specific inhibitors, the hPSCs are guided to differentiate towards a neuronal lineage, forming neuroectodermal colonies. Special growth factors are then introduced, which encourage the self-organization and proliferation of the colonies, ultimately leading to the formation of spherical brain organoids.
