''It seems more than ever likely that blood-derived stem tive capacity. 47-49 In the allogeneic
setting, mobilized blood cells have also been used instead of BM. 50 Umbilical cord cells …

Reported in 1989, studies by Broxmeyer, Gluckman, and colleagues demonstrated that
umbilical cord blood (UCB) is a rich source of hematopoietic stem/progenitor cells (HSPC) …

Hematopoietic progenitor cells migrate in vitro and in vivo towards a gradient of the
chemotactic factor stromal cell-derived factor-1 (SDF-1) produced by stromal cells. This is …

The aim of this study was to study interactions between stromal bone marrow
microenvironment and leukemic cells. We tested the hypothesis that stromal cells prevent …

To clarify whether the expression of the WT1 gene in leukemic cells is aberrant or merely
reflects that in normal counterparts, the expression levels of the WT1 gene were quantitated …

The first step in the homing of hematopoietic progenitor cells (HPCs) from the peripheral
blood to the bone marrow involves an adhesion molecule-dependent contact with human …

The human polyomavirus JC virus (JCV) infects myelin-producing cells in the central
nervous system, resulting in the fatal demyelinating disease progressive multifocal …

Background Whether umbilical cord blood (UCB) serves as a source of mesenchymal
stem/progenitor cells (MSPC) is controversial. MSPC are the best candidates for cellular …

Multilineage differentiation of human fetal bone marrow CD34+ cell subsets was examined
using a single-cell liquid culture assay. Four CD34+ cell populations, ie,(1) CD38-, HLA …

We have recently described a marrow stroma-dependent long-term culture system that
supports differentiation of CD34+ human marrow primitive progenitors into natural killer (NK) …
