Figure 1. c-Maf expression in the spinal cord and sensory neurons. Analysis of c-Maf expression in the dorsal spinal cord (left) and dorsal root ganglia (right). In the dorsal spinal cord, c-Maf (green) is expressed in layer III neurons that receive mechanosensory information from the periphery. In dorsal root ganglia, c-Maf (green) is expressed in large diameter neurons that co-express Ret (red). For the analysis shown on the left, mice that carry a heterozygous c-Maf^lacZ allele were used. In c-Maf^lacZ mice, LacZ is expressed under the control of the c-Maf locus, and expression of the LacZ gene product, β-galactosidase, is useful to follow the expression of the allele.
