Sensory neurons have proven very useful for analysis of neuronal differentiation in vivo and in vitro. Their utility for in vitro work is based on the fact that sensory neurons are relatively easy to isolate in large numbers and are amenable to manipulations in culture. Lumbar ganglia are usually used because their location in the caudal nervous system means they are the least differentiated at any developmental stage, allowing the analysis of relatively undifferentiated cells. Rodent sensory ganglia from embryonic to adult stages can be dissected effectively and maintained in serum-free medium or in coculture with other cells or factors. This unit describes generation of embryonic rat lumbar dorsal root ganglia (DRG) cultures, which form an important model system for investigating the cellular and molecular mechanisms that regulate neuronal differentiation. Adult DRG can also be successfully cultured, with a few modifications of the general protocol.
