Figure 1

Differentially expressed genes in CD34+ cells compared to more differentiated cells. Visualization of expression of 2518 genes that were more highly expressed in CD34+ cells (A), and 1867 genes that were expressed at lower levels (B) compared to each of the three other cell types (indicated at the top). Genes were identified by a pairwise comparison of CD34+ cells with each of the other 3 cell types in 23 individuals. Red indicates a high level of expression, green a low expression level, and black indicates intermediate expression
