objective(s): the aim of this study was to estimate effects of hyperbaric (hb) treatment by determination of cd15s and cd11b leukocyte proinflammatory markers expression.  in addition, this study describes changes in cd77 and cd34 expression on rat endothelial cells in renal, pulmonary and cardiac tissue following exposure to hyperbaric pressure. materials and methods:expression of cd11b and cd...

Several studies have previously demonstrated enrichment in primitive progenitor cells in subfractions of CD34+ bone marrow (BM) cells not expressing CD38 or HLA-DR (DR) antigens. However, no studies have directly compared these two cell populations with regard to their content of primitive and more committed progenitor cells. Flow cytometric analysis of immunomagnetic isolated CD34+ cells demon...

abstract background b cells play an important role in the immune system due to production of the immunoglobulin and secreting several cytokines. it has been shown that b cells produced successfully in the presence of stem cell factor (scf) and flt3 ligand (flt3l). il2, il7, and il15 cytokines as  -common family have an essential cytokines may support either synergistically or in an additi...

introduction: a number of potential cell adhesion molecules, which mediate essential cell-to-cell or cell-to-matrix interactions, are expressed on the surface of cd34+ hematopoietic progenitor cells (hpcs), including integrins, cd44, and cxcr4. these molecules are essential for homing process. in this study, we compared the changes of expression of cd44 and cxcr4 on the cd34+ hematopoietic prog...

Several peripheral blood mononuclear cell (PBMC)-derived cell populations can promote angiogenesis, and differences in CD34(+) or CD14(+) surface expression have been used to separate PBMC subpopulations in this respect. AngiomiRs, microRNAs regulating angiogenesis, are key regulators of angiogenic processes. The present study examines differential angiomiR expression/secretion from CD34(+)/CD1...

In Human Erythroid Massive Amplification (HEMA) cultures, AB mononuclear cells (MNC) generate 1-log more erythroid cells (EBs) than the corresponding CD34(pos) cells, suggesting that MNC may also contain CD34(neg) HPC. To clarify the phenotype of AB HPC which generate EBs in these cultures, flow cytometric profiling for CD34/CD36 expression, followed by isolation and functional characterization...
