Figure 2. Histograms of gene expression data for DRG and sciatic nerve.

Figure 2

Genes from transcriptomic data were ranked by RPKM values and binned according to level of expression. In both tissue types, number of detectable annotated genes decreases as RPKM value increases, with a small number of genes expressed at extremely high levels. Compared with the DRG, which is a more diverse tissue containing several types of neurons, satellite cells, fibroblasts, and Schwann cells, the sciatic nerve is more homogeneous containing mostly Schwann cells and some adipose. The extremely high level of expression of myelin-related proteins in Schwann exceeds the level of any transcript from DRG.
