The transcriptome of human CD34+ hematopoietic stem-progenitor cells.

ABSTRACT: Studying gene expression at different hematopoietic stages provides insights for understanding the genetic basis of hematopoiesis. We analyzed gene expression in human CD34(+) hematopoietic cells that represent the stem-progenitor population (CD34(+) cells). We collected >459,000 transcript signatures from CD34(+) cells, including the de novo-generated 3' ESTs and the existing sequences of full-length cDNAs, ESTs, and serial analysis of gene expression (SAGE) tags, and performed an extensive annotation on this large set of CD34(+) transcript sequences. We determined the genes expressed in CD34(+) cells, verified the known genes and identified the new genes of different functional categories involved in hematopoiesis, dissected the alternative gene expression including alternative transcrip
