Understanding the mechanisms that underlie human brain development and neurological and neuropsychiatric disorders is one of the key topics of neurobiology. Because of the poor accessibility of human and non-human primate brain tissues, the current perception and understanding of human brain development have been mainly derived from studies of rodents. However, some human-specific features of neural development cannot be well characterized by these animal models. Thanks to the advances in stem cell technologies, brain organoids are being under rapid development, showing the promising applications in decoding the human brain development and uncovering the pathology of brain diseases. In this review, we mainly summarized the recent advances in the development of brain organoid technology and discussed the limitations, applications and future prospects of this promising field.
