Expression data from human CD34+ HPC subpopulations isolated from umbilical cord blood (Haddad et al. Blood 104:3918, 2004)

ABSTRACT: We used microarrays to analyze the gene expression profile of CD34+CD45RA+CD7+, CD34+CD45RA+CD10+CD19- and CD34+CD45+CD7-CD10-CD19- HPCs isolated from umbilical cord blood CD34+CD45RA+CD7+(CD10-) and CD34+CD45RA+CD10+(CD7-CD19-) HPCs correspond respectively to prothymocytes and early pre-proB precursors. CD34+CD45RA+CD7-CD10-CD19- HPCs correspond to lympho-granulo-macrophagic precursors The corresponding populations were sorted from total CD34+ HPCs isolated from 2 or 3 individual donors

The early stages of human lymphopoiesis are poorly characterized. Here, we compared the lymphoid potential of a novel umbilical cord blood CD34(+)CD45RA(hi)CD7(+) hematopoietic progenitor cell (HPC) population with that of CD34(+)CD45RA(hi)Lin(-)CD10(+) HPCs, previously proposed as candidate common lymphoid progenitors. Limiting-dilution and clonal analysis, fetal thymic organ cultures, and culture onto Notch ligand Delta-like-1-expressing OP9 cells, showed that although CD34(+)CD45RA(hi)CD7(+)  ...[more]
