CD34

a type I transmembrane protein present on myeloid cells and myeloid precursors that plays a role in signal transduction; expressed in some acute nonlymphocytic leukemias and some acute lymphocytic leukemias.

CD34

A membrane-bound cell surface antigen present on and identifying T cells, monocytes, and macrophages. It is found principally on endothelial cells and blood-forming stem cells, and regulates cell-to-cell adhesion.

n the current study, they show that the two groups of the melanocyte stem cells can be identified and separated based on whether they are coated in a glycoprotein called CD34, a surface molecule which is present on other types of stem cells, including stem cells of the blood.
The primary panel of monoclonal antibodies (mAbs) used were CD45 (for blast identification), CD13, CD33, CD34, HLA-DR and for AML M4/M5 CD14, for AML M6 anti-glycophorin A and for AML-M7, CD61, CD41 and CD42 were used.
The minimum CD34 threshold depends on prior chemotherapy in autologous peripheral blood stem cell recipients.
Patients with MF frequently present with blood showing a leucoerythroblastic picture and an increased number of circulating hematopoietic progenitor cells (HPC) characterized by the expression of CD34 antigen.
CD34, a glycosylated single-chain protein with an approximate weight of 116 kDa (11), is one of the single-pass transmembrane sialomucin proteins and intercellular adhesion factors.
The pulp vasculature in all regions of immature and mature teeth was positive for CD34 and CD146, and there was a homogeneous staining pattern from the capillaries to the larger blood vessels.
Fresh samples from G-BM and G-PB were stained with MoAb for flow cytometry analysis of the following surface antigens: CD45, CD3, CD4, CD8, CD14, and CD34. The absolute dose of graft compositions was calculated as a percentage of CD34+ cells, CD3+ T cells, CD3+ CD4+ T cells, CD3+ CD8+ T cells, CD3+ CD4- CD8- T cells, and monocytes (MO), labeled with a four-color Ab cocktail within the side scatter low and CD45+ lymphocyte gate multiplied by the total MNC and divided by the actual donor weight to determine the cell dose per kg.[26],[28] Acquisition and analyses were performed using CellQuest software (Becton-Dickinson, San Jose, CA, USA).

MNCs were then processed on magnetic columns for [CD34.sup.+] cell isolation (mean purity 94 [+ or -] 4%) (CD34 Isolation kit; Miltenyi Biotec, Bologna, Italy), as previously described [25], and treated with our combination of cytokines on the same day.
Human fetal liver samples were obtained from Advanced Bioscience Resources; human [CD34.sup.+] hematopoietic progenitor cells were isolated using the human CD34 MicroBead kit (Miltenyi Biotec).
