Neural stem cells (NSCs) and neural progenitor cells self-renew and differentiate into the the neurons, astrocytes and oligodendrocytes of the mammalian central nervous system, and thus have great potential for both neurobiological research and treatment of neurological disorders. Methodologies for in vitro culturing of NSCs and progenitors have since been described, detailing specialized growth conditions. Fortunately, ready-to-use neural stem cell media are available from a number of commercial sources. Visit the supplier pages for specific details on media formulations such as supplementation.
