Pearson’s coefficients for similarity for the postvaccine expression profile across all transcripts (averaged from GBM patient samples) were determined, plotted against the first set of coefficients for each and every patient, and correlation among CSC and vaccineinduced expression profiles calculated using exponential trendlines.
