FIGURE 3. Normalized log-transformed median-centered gene expressions for significant inflammatory related genes are graphed for each donor (A–D). The y-axis depicts log₂ gene expression signal values ranging from −3.0 to 3.0 magnitudes and the x-axis shows the 4 different treatment groups bracketed by each inflammatory gene (designated abbreviations listed in the Fig 2. table). Intradonor comparisons show that the PRBC group (III) collectively induced greater proinflammatory gene expression levels than the other 3 groups.
