Abstract

This protocol generates polarized cerebellar tissue structures from human embryonic stem cells (ESCs) through 3D culture with sequential growth factor addition. The self-organized neuroepithelium differentiates into functional cerebellar cell types including Purkinje cells, granule cells, and interneurons, recapitulating early human cerebellar ontogenesis.

Application
