Expression profiling of purified hematopoietic stem cells from patients with MDS and healthy controls

ABSTRACT: Gene expression analysis on purified human long-term hematopoietic stem cells (LT-HSC; CD34+CD38-CD90+) and short-term HSC (ST-HSC; CD34+CD38-CD90-) derived from healthy control patients and patients with myelodysplastic syndrome (MDS) Overall design: Analysis of gene experssion of ST-HSCs and LT-HSCs derived from two patients with MDS and three healthy controls

Even though hematopoietic stem cell (HSC) dysfunction is presumed in myelodysplastic syndrome (MDS), the exact nature of quantitative and qualitative alterations is unknown. We conducted a study of phenotypic and molecular alterations in highly fractionated stem and progenitor populations in a variety of MDS subtypes. We observed an expansion of the phenotypically primitive long-term HSCs (lineage(-)/CD34(+)/CD38(-)/CD90(+)) in MDS, which was most pronounced in higher-risk cases. These MDS HSCs  ...[more]
