Differentially expressed genes for different sample preparation procedures, from a representative subset of eight tumor–nontumor pairs for which all three tissue-sampling platform types were available: macroscopic–conventional homogenized (Macro), macroscopic–conventional homogenized small aliquot undergoing Pico preamplification (Macro–Pico) controls, and LCM samples also undergoing Pico preamplification (LCM). The corresponding gene lists, including overlap lists, are available from Gene Expression Omnibus (https://www.ncbi.nlm.nih.gov/geo; accession number GSE31552).
