  1. The table reports a selected list of genes up-regulated and strictly related to peculiar biological role of each lineage. Significantly over-expressed genes were identified performing pairwise comparisons between each precursor cell type and CD34+ cells, using SAM analysis with fairly stringent conditions. This constitute a partial list of differentially expressed genes: complete lists are available in Additional file 4.
