Angiogenesis in the human temporomandibular joint studied by immunohistochemistry for CD34 antigen
Journal of Oral Pathology & Medicine, 1999The CD34 antigen is a sensitive marker of vascular endothelium and angiogenesis. Thus, we examined the expression of CD34 in 20 human temporomandibular joint (TMJ) samples with internal derangement and in 10 control specimens by an immunohistological technique using paraffin‐embedded tissue and specific anti‐human CD34 monoclonal antibody.

Separation of CD34 positive cells and determinationof surface homing antigen
Current Medical Science, 2000To study the differences in homing potential between bone marrow cells and umbilical blood cells, CD34 positive cells were obtained from bone marrow (BM) and umbilical blood (UB) by the direct cell separation with domestic immunomagnetic beads. The expression of the two adhesion molecules CD11a/CD18 and CD44 were examined.

Expression of CD34 antigen in testicular mixed germ cell tumor
Pathology International, 2003The expression of CD34 was investigated in 14 cases of testicular mixed germ cell tumor to elucidate the relationship between its expression and histological patterns. Seven of 12 yolk sac tumor components were focally immunoreactive for anti‐CD34 antibody.

Decreased Expression of the Human Progenitor Cell Antigen (CD34) in Morphea
The American Journal of Dermatopathology, 1995Morphea is an idiopathic disorder the hallmark of which is fibrosis of the skin. The regulatory factors resulting in the increased collagen production have not been determined. Within the dermis there are dendritic cells with possible immunological functions that express either the human progenitor cell antigen (CD34) or factor XIIIa ...

Hematopoietic Stem Cell Antigen CD34: Role in Adhesion or Homing
Stem Cells and Development, 2006CD34 is highly glycosylated surface antigen of enormous clinical utility in the identification, enumeration, and purification of engraftable lymphohematopoietic progenitors for transplantation. However, recently its importance in the specific marking of most immature hematopoietic stem/progenitor cells have been questioned by addressing long-term ...

Electron microscopy demonstration of CD34 antigen on progenitor pseudopodia
Experimental Hematology, 2000Abstract Current theory predicts stem cells are CD34-negative, despite CD34 use for therapeutic progenitor purification. Expressed on early haemopoietic cells, it is implicated in cellular adhesion, and marrow stromal cell homing. There are 2 CD34 forms, one intracellularly truncated, hypothesised for adhesion alone, with the extended variant capable ...

Immunoreactivity for the Human Hematopoietic Progenitor Cell Antigen (CD34) in Lipomatous Tumors
The American Journal of Surgical Pathology, 1997The human hematopoietic progenitor cell antigen (CD34) recently was shown to react with a variety of nonhematopoietic tissues and their tumors, including vascular endothelium, dendritic interstitial fibroblastic cells, and endoneurial cells as well as with the neoplastic cells in a variety of mesenchymal neoplasms of unknown etiology, such as Kaposi's ...

Effects of Raloxifene on Ki-67 and CD34 Antigen Expression in Breast Cancer
Gynecologic and Obstetric Investigation, 2008<i>Background:</i> The aim of this study was to evaluate the effect of raloxifene on CD34 and Ki-67 antigen expression in breast cancer specimens from postmenopausal women. <i>Methods:</i> Sixteen postmenopausal patients with operable, stage II (≥3 cm), estrogen receptor-positive breast cancer, who took 60 mg of raloxifene daily

Structural and functional features of the CD34 antigen: an update.
Journal of biological regulators and homeostatic agents, 2001CD34 is a heavily glycosylated type I transmembrane molecule, that can be phoshorylated by a variety of kinases including Protein kinase C and Tyrosine kinases. The classification of epitopes detected by different CD34 MAbs has aided the selection of appropriate antibodies for use in specific clinical and research laboratory settings.

Sequential expression of CD34 and CD33 antigens on myeloid colony‐forming cells
European Journal of Haematology, 1989The expression of CD33 and CD34 antigens on human bone marrow cells was examined by fluorescence‐activated cell sorting and colony assays. A marked difference of antigen expression was observed on sorted progenitors of the granulocyte/macrophage lineage (CFU‐GM) with respect to enrichment and maturation status.
