Human brain development exhibits a number of unique characteristics, such as dramatic size expansion, unique cell types, and distinct neural stem cell behaviors. These characteristics are difficult to examine in model organisms such as mice and are often involved in neurological diseases unique to humans, like autism and schizophrenia. In an effort to better understand human brain development, we have developed a new model system, called cerebral organoids. Cerebral organoids, or mini-brains for short, are 3D tissues generated from human pluripotent stem cells that allow modelling of human brain development in vitro. Through a process of directed differentiation and a supportive 3D microenvironment, neural precursor tissue can spontaneously self-organize to form the stereotypic organization of the early human embryonic brain. Our current interests focus on neurodevelopmental disorders, as well as comparative evolutionary studies aimed at identifying factors in human brain evolution.
