The CD34 antigen: Potential clinical advantages of CD34 selection

Clinical Oncology, 1996
The availability of monoclonal antibodies directed towards the haemopoietic cell surface antigen CD34 has facilitated accurate measurement, by flow cytometry, of CD34 positive cell frequencies in bone marrow and peripheral blood. In addition, a range of CD34 selection techniques, to purify peripheral blood progenitor cells or bone marrow prior to ...

Kinetics of engraftment of CD34− and CD34+ cells from mobilized blood differs from that of CD34− and CD34+ cells from bone marrow

Experimental Hematology, 2000
Mobilized peripheral blood (PB) progenitors are increasingly used in autologous and allogeneic transplantation. However, the short- and long-term engraftment potential of mobilized PB or bone marrow (BM) has not been directly compared. Although several studies showed that BM-derived Lin(-)CD34(-) cells contain hemopoietic progenitors, no studies have ...

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‐reactive trichodiscoma

Journal of Cutaneous Pathology, 2004
Background:  Trichodiscomas are rare hamartomas of the dermal portion of the hair disc, a specialized component of the perifollicular mesenchyme. They are usually found as asymptomatic multiple skin‐colored papules on the face and extremities and may have an autosomal dominant inheritance pattern.

CD34+ and CD34+VEGFR2+ cells in poorly controlled hypertensive patients

Journal of Human Hypertension, 2018
CD34+ and CD34+VEGFR2+ cells participate in the repair of damaged endothelium and vascular remodelling. As their number and activity change due to the development of cardiovascular diseases, they are recognised as useful markers of cardiovascular health.

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 ...

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

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‐positive eruptive fibromas

Journal of Cutaneous Pathology, 1998
The list of entities comprising a proliferation of CD34 (+) spindle cells continues to grow. Described, herein, is a patient who had an indolent eruption of scattered papules composed of CD34 (+) spindle cells, beginning in adolescence.An 18‐year‐old female patient presented with asymptomatic, tan/brown papules over the neck, chest, and proximal ...

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 ...
