  1. Samples selected for the meta-analysis of gene expression profiles in DS AMKL (pool 'A'), non-DS AMKL (pool 'B'), TMD (pool 'C'), and megakaryocytic cells (pool 'D' and 'E'). All Sample IDs and Platforms IDs are related to GEO database, other than codes marked with * (ArrayExpress database). Sample type: BM, bone marrow; PB, peripheral blood; BMMC, bone marrow mononuclear cells; PBMC, peripheral blood mononuclear cells; MK, megakaryocytic/megakaryoblast cells, obtained by in vitro differentiation of CD34+ cells; CD34+, undifferentiated CD34+ cells; BM, CB or PB: CD34+ cells derived from bone marrow, cord blood or peripheral blood, respectively. subj = number of subjects from which the sample was derived (in some cases, where subj = pool, the exact number of subjects included in a pool was not available). rep. = biological replicate. Microarray: U133A: Affymetrix Human Genome U133A Array; 1A: Agilent-012097 Human 1A Microarray (V2) G4110B; 22k A: Agilent Human oligo 22k A; HG-Focus: Affymetrix Human HG-Focus Target Array.
