Differential increase of CD34, KDR/CD34, CD133/CD34 and CD117/CD34 positive cells in peripheral blood of patients with acute myocardial infarction

Clinical Research in Cardiology, 2007
Circulating progenitor cells (CPC) may contribute to cardiac regeneration and neovascularization after acute myocardial infarction (AMI). For potential therapeutic use, understanding the endogenous mechanisms after ischemia is inevitable. We investigated the absolute number, but also the subset composition of CD34+ CPC after AMI.CD34+, KDR+/CD34 ...

CD34+ or CD34−: Does it Really Matter?

Blood, 1999
T HE CELL SURFACE glycoprotein CD34 has been the focus of intense interest ever since its discovery on a small fraction of human bone marrow cells.[1][1] The CD34+population appears responsible for most, if not all, of the hematopoietic activity in bone marrow, including colony formation in short-

CD34+ Leukemic Cells Assessed by Different CD:34 Monoclonal Antibodies

Leukemia & Lymphoma, 1995
CD34 monoclonal antibodies (McAbs) are widely used to identify and isolate hemopoietic progenitors and to classify acute and chronic leukemias. We assessed the reactivity of 17 CD34 McAbs from the 5th International Workshop on Leukocyte Differentiation Antigens with a variety of cells types: normal bone marrow hemopoietic progenitors, 10 AML, 6 ALL, 11

Transduction of CD34+ and CD34−/lin− hemopoietic progenitors by lentivirus vectors

Cytotherapy, 1999
While hemopoietic stem cells have been thought to reside predominantly in the CD34(+) population, recent data suggests that repopulating cells may, in fact, also reside in the lin(-)/CD34(-) population. Transduction of both these populations by murine retroviral vectors is limited by quiescence of hemopoietic stem cells.We therefore sought to transduce

CD34 measurement: setting standards

Cytotherapy, 2014
Flow cytometric analysis has provided the hematopoietic transplant community with a powerful and rapid tool for assessing the engraftment potential of stem cell products. As described by Preti et al. [1] in this issue of the Journal, this was made possible by the identification of the CD34 antigen, and the commercial availability of fluorescently ...

Molecular cloning of feline CD34

Veterinary Immunology and Immunopathology, 2003
In humans, baboons, dogs and mice CD34 is a cell surface molecule that is expressed on primitive hematopoietic cells and in all these species CD34 positive cells can be used to effect long-term haematopoietic reconstitution. CD34 positive haematopoietic cells therefore provide a convenient and relatively small cell population to target when attempting ...

CD34 expression in desmoplastic melanoma

Journal of Cutaneous Pathology, 2001
Background: Primary and metastatic malignant melanoma can simulate various soft tissue tumors, including dermatofibrosarcoma protuberans (DFSP). Expression of CD34, a marker characteristic of DFSP, as well as other spindle cell tumors, has not been previously documented in malignant melanoma.Methods: We present here an unusual case of metastatic ...

CD34-Reactive Myxoid Dermal Dendrocytoma

The American Journal of Dermatopathology, 2002
Normal skin is composed in part of cells that express CD34. These include periadnexal spindle cells, vascular endothelial cells, and interstitial dendritic cells. We report on a tumor composed mainly of CD34-reactive spindle cells. A 66-year-old Japanese woman presented with a skin-colored, dome-shaped, cutaneous papule on her left palm that was 7 mm ...
