Chronic myeloid leukemia (CML) is a myeloproliferative disease derived from an abnormal hematopoietic stem cell (HSC) and is consistently associated with the formation of Philadelphia (Ph) chromosome. Tyrosine kinase inhibitors (TKIs) are highly effective in treating chronic phase CML but do not eliminate leukemia stem cells (LSCs), which are believed to be related to disease relapse. Therefore, one major challenge in the current CML research is to understand the biology of LSCs and to identify the molecular difference between LSCs and its normal stem cell counterparts. Comparing the gene expression profiles between LSCs and normal HSCs by DNA microarray assay is a systematic and unbiased approach to address this issue. In this paper, we present a DNA microarray dataset for CML LSCs and normal HSCs to show that the microarray assay will benefit the current and future studies of the biology of CML stem cells.
