(a) Estimated latent factors for each gene using ALL and AML samples. Genes in the upper left quadrant tend to be overexpressed in the AML samples, but underexpressed in the ALL samples, and genes in the lower right quadrant tend to be overexpressed in the ALL samples, but underexpressed in the ALL samples. (b) Log (base 10) of gene expression levels for genes differentially expressed between ALL and AML samples.
