SUMMARY

The discussion focuses on the development of human pluripotent stem cell-derived cerebral organoids, which are three-dimensional organoid cultures that replicate various brain regions, including the cerebral cortex. These organoids exhibit characteristic features of human cortical development, such as organized progenitor zones and the presence of outer radial glial stem cells. This innovative approach represents a significant advancement in neuroscience, potentially leading to breakthroughs in understanding brain development and disorders.

Here we have developed a human pluripotent stem cell-derived three-dimensional organoid culture system, termed cerebral organoids, that develop various discrete, although interdependent, brain regions. These include a cerebral cortex containing progenitor populations that organize and produce mature cortical neuron subtypes. Furthermore, cerebral organoids are shown to recapitulate features of human cortical development, namely characteristic progenitor zone organization with abundant outer radial glial stem cells.
