Abstract
Stem cells are the source of diverse cell types, and therefore their fate decisions are tightly regulated by multiple layers of controls in each tissue. Without a doubt, the brain is one of the most complex and highly functional tissues, as we now know more than 70 million neurons and even more non-neuronal cells are distributed across dozens of cortical areas in the mouse cerebral cortex, and a single region of cortex contains more than 40 cell types. These diverse neuronal cells emerge from initially homogeneous neural stem cells during embryonic development. In the course of differentiation, neural stem cells undergo cellular division to produce daughter cells with new cellular identities, during which epigenetic and transcriptional regulations determine their fate. Recent advances in the field of neural stem cell biology have revealed that not only epigenetic regulators and transcription factors but also specialized intracellular organelles regulate many aspects of stem cell functions and fate choices, and therefore it is timely to review the mechanisms of sophisticated changes of the properties of neural stem cells during development and how they impact the function of the daughter cells.
