Apoptosis in Relation to CD34 Antigen Expression in Normal and Myelodysplastic Bone Marrow

Acta Haematologica, 2002
An increased bone marrow (BM) apoptosis is one of the mechanisms responsible for the ineffective hematopoiesis of myelodysplastic syndromes (MDS). It is controversial whether the excessive apoptosis in myelodysplasia predominantly involves the subset of progenitor cells or of maturing cells.

Novel transcription factors in human CD34 antigen–positive hematopoietic cells

Blood, 2002
AbstractTranscription factors (TFs) and the regulatory proteins that control them play key roles in hematopoiesis, controlling basic processes of cell growth and differentiation; disruption of these processes may lead to leukemogenesis. Here we attempt to identify functionally novel and partially characterized TFs/regulatory proteins that are expressed

Chromosome 1 localization of the gene for CD34, a surface antigen of human stem cells

Cytogenetics and Cell Genetics, 2008
CD34 is a surface antigen expressed on normal human hematopoietic stem cells, as well as on the blast cells of many patients with both lymphocytic and myelocytic leukemias. By Southern blot analysis of DNA from a panel of human × mouse somatic cell hybrids using a CD34 cDNA probe, we demonstrate that the gene for CD34 is located on human chromosome 1 ...

Expression of haematopoietic progenitor cell-associated antigen BI-3C5/CD34 in leukaemia

Leukemia Research, 1989
The expression of progenitor cell-associated antigen CD34, defined with monoclonal antibody BI-3C5, was investigated in cells from 109 patients with leukaemia. No reactivity was found in chronic leukaemias, whereas 31% of acute myelogenous leukaemia (AML) and most non-T, non-B acute lymphoblastic leukaemia (ALL) expressed CD34.

Human Dental Pulp Vasculogenesis Evaluated by CD34 Antigen Expression and Morphological Arrangement

Journal of Dental Research, 2003
Vasculogenesis describes the process by which endothelial precursor cells form new blood vessels. To characterize the topography and the cellular processes underlying vascularization of human dental pulp, we examiend the expression of the human hematopoietic progenitor cell antigen CD34.

[Polyclonal antibodies against human cell-surface antigen CD34].

TSitologiia i genetika, 2011
An efficient and inexpensive laboratory approach for the generation and the purification of polyclonal antibodies to human antigen CD34 was developed. It was shown that cloned refolded and purified from Escherichia coli recombinant extracellular fragment of CD34 antigen retained immunogenic determinants of cell-surface expressed CD34.

[Sorting CD34 antigens: objectives, biological and clinical results].

Presse medicale (Paris, France : 1983), 1999
CD34 SORTING: CD34 sorting is a means of selecting hematopoietic stem cells among heterogeneous populations of cells. The technique is based on the fact that only hematopoietic stem cells (excepting a few tumoral cells) carry the CD34 antigen. Generally this type of manipulation is performed in case of stem cell grafts or for the treatment of certain ...

[CD34+ antigen expression relating to prognosis in acute myeloid leukemia].

Zhongguo shi yan xue ye xue za zhi, 2008
To explore CD34(+) antigen expression in new diagnosed acute myeloid leukemia (AML) and analyze the prognosis for CD34(+) AML patients, the expression of antigen CD34 in 238 AML patients was detected by indirect immunofluorescence assay. The results showed that CD34 in 92 out of the 238 patients (38.7%) were positive, there was relationship between the

Myeloid antigen expression on CD34 positive blasts in myelodysplastic syndromes

2006
Background: The myelodysplastic syndromes (MDS) constitute a heterogeneous group of clonal hematopoietic stem cell disorders. They are characterized by abnormal bone marrow (BM) differentiation, peripheral blood cytopenias and a risk of transformation into acute myeloid leukemia (AML).
