pubmed-article:12119411 | pubmed:abstractText | In an attempt to characterize early B cell development including the commitment of progenitor cells to the B cell lineage, we generated and compared genomewide gene expression profiles of human hematopoietic stem cells (HSCs) and pre-B cells (PBCs) by using serial analysis of gene expression. From more than 100,000 serial analysis of gene expression tags collected from human CD34(+) HSCs and CD10(+) CD19(+) PBCs, 42,399 unique transcripts were identified in HSCs but only 16,786 in PBCs, suggesting that more than 60% of transcripts expressed in HSCs were silenced during or after commitment to the B cell lineage. On the other hand, mRNAs of pre-B cell receptor (pre-BCR)-associated genes are virtually missing in HSCs but account for more than 10% of the transcriptome of PBCs, which also show increased expression of apoptosis-related genes. Both concentration of the transcriptional repertoire on pre-BCR-related genes together with marked up-regulation of apoptosis mediators in PBC might reflect selection for the expression of a functional pre-BCR within the bone marrow. Besides known regulator genes of early B cell development such as PAX5, E2A, and EBF, the most abundantly expressed genes in PBCs include ATM, PDGFRA, SIAH1, PIM2, C/EBPB, WNT16, and TCL1, the role of which has not been established yet in early B cell development. | lld:pubmed |
