Gene expression data on sorted LT-HSCs (Lin−, CD34+, CD38−, CD90+), ST-HSCs (Lin−, CD34+, CD38−, CD90−), GMPs (Lin−, CD34+, CD38+, CD123+, CD45RA+) from patients with AML/MDS and healthy controls have been deposited in the GEO database (GSE35008 and GSE35010). This evidence concerns the gene CD34 and myelodysplastic syndrome.
