Figure 2.

Pairwise scatterplots revealing intra-/inter-sample relationships. Sample gene counts from nociceptor transcripts were log10-transformed in R and were analyzed for quality and inter-/intra-relationships by pairwise scatterplots of all samples in both groups (Control vs. UV-injured). Each dot within the scatterplot represents a gene, and the mean expression of that gene between the two samples shown by its x-y coordinate placement. n = 3 (pooled samples)/group (Control vs. UV-injured).
