Figure 7. GPCR expression in sciatic nerve.

Differentially expressed GPCRs in sciatic nerve were extracted and plotted by sample number to observe sample-to-sample variation. These genes were subsequently subcategorized by degree of sample to sample variation, used here as a surrogate for contribution from variable levels of adipose or other adherent tissue (see Figure 6). GPCRs with a weak pattern or no pattern of sample to sample variation are most likely expressed by major cell types of the sciatic nerve, such as Schwann cells, while those with a strong variable pattern indicate that they are most likely produced by adipose (leftmost panel).
