Comparison of expression profile for selected genes between the three different procurement methods. Expression profile of selected genes between the 3 different methods show a greater degree of similarity between Groups 1 and 3 than either with Group 2. Redundant genes indicate the presence of multiple probes, with the genes in the lower half of the cluster diagram indicating degeneration at one end of the mRNA species for that gene.
