Small cell lung cancer can express CD34 antigen.

Anticancer research, 1998
In humans CD34 is a valid and reliable marker for hematopoletic stem and progenitor cells. In general, solid tumors, with the exception of endothelial cancers, do not express CD34. Accordingly, immunological selection of CD34+ hematopoietic stem/progenitor cells can be used to remove CD34- malignant cells in the setting of autotransplantation.

CD34 antigen expression of acute myeloid leukemia-colony forming cells

The International Journal of Cell Cloning, 1992
Hematopoietic The International Journal of Cell Cloning express the CD34 antigen on their surface. Their proportion in a harvest can provide a quick and reliable measure of the hemopoietic efficiency of the harvest. In ANLL a variable proportion of blast cells express the same antigen: the aim of our study was to investigate whether clonogenic ANLL ...

Angiogenesis in the human temporomandibular joint studied by immunohistochemistry for CD34 antigen

Journal of Oral Pathology & Medicine, 1999
The 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.

Immunoreactivity for the Human Hematopoietic Progenitor Cell Antigen (CD34) in Lipomatous Tumors

The American Journal of Surgical Pathology, 1997
The 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 ...

Expression of hematopoietic progenitor cell associated antigen CD34 in chronic myeloid leukemia

Leukemia Research, 1991
The expression of progenitor cell associated antigen CD34 was investigated in cells from 28 patients with chronic myeloid leukemia (CML). The CD34 positivity varied from 0-26% in patients with chronic phases CML (n = 17); from 6-64% in patients with accelerated phase CML (n = 4); and from 27-97% in the patients with blastic crisis of CML (n = 8).

[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.

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.

Structural and functional features of the CD34 antigen: an update.

Journal of biological regulators and homeostatic agents, 2001
CD34 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.

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.

CD34 antigen expression in children with philadelphia chromosome-positive acute lymphoblastic leukemia

Cancer, 1991
One characteristic of Philadelphia chromosome (Ph')-positive acute leukemia is the occasional presence of both lymphoid and myeloid features in the same leukemia. This phenomenon supports the theory that this subtype of acute leukemia arises from lymphoid-myeloid stem cell, pluripotent progenitors.
