Heat Map Representation of Differentially Regulated Transcripts

<div><p>Rows represent genes and columns represent array comparisons between cell populations as indicated.</p> <p>(A) Significance score by SAM is indicated from top to bottom of each comparison (<i>n</i> = 6) by gradients of yellow or blue, with brighter yellow or blue indicating higher significance. Yellow or blue in additional columns indicate that the gene was also differentially expressed between these cell types (e.g., many of the genes upregulated in MPP versus LT-HSC were also upregulated in ST-HSC compared to LT-HSC).</p> <p>(B) Conventional red-green expression data for all the differentially regulated genes for each array. Red indicates genes upregulated in the more differentiated cell population (e.g., upregulated in MPP when compared to LT-HSC); green indicates upregulated in the less differentiated cell population.</p>
