Evaluation of Angiogenesis in Colorectal Carcinoma by CD34 Immunohistochemistry Method and its Correlation with Clinicopathologic Parameters [PDF]

open access: yesActa Medica Iranica, 2009
The basic pathogenic step in the process of tumor growth, invasion and metastasis is tumor-induced angiogenesis. The aim of this study was to evaluate the angiogenesis in colorectal carcinoma by microvascular density (MVD) determination with IHC ...

Three‐dimensional distribution patterns of CD34 antigen on nonactivated cord blood cells [PDF]

open access: yesCytometry Part A, 2007
AbstractCirculating immature blood cells are inhomogeneous in most cytometric parameters, including CD34 expression. This surface antigen forms patches, and we studied their spatial distribution pattern by processing staggered and digitalized microscopical images; the number, fluorescence intensity, and volume were determined in randomly identified ...

Arsenite exposure inhibits the erythroid differentiation of human hematopoietic progenitor CD34+ cells and causes decreased levels of hemoglobin

open access: yesScientific Reports, 2021
Arsenic exposure poses numerous threats to human health. Our previous work in mice has shown that arsenic causes anemia by inhibiting erythropoiesis. However, the impacts of arsenic exposure on human erythropoiesis remain largely unclear.

Evaluation of human umbilical cord blood as a source of embryonic stem cells [PDF]

open access: yes, 2013
Human umbilical cord blood (HUCB) has been poorly characterised as a source of embryonic stem cells (ESCs). The aim of this study, therefore, was to evaluate HUCB as source of mesenchymal stem cells (MSCs) with embryonic characteristics.

Using the nonhuman primate model of HCMV to guide vaccine development. [PDF]

open access: yes, 2014
The natural history of human cytomegalovirus (HCMV) is inextricably associated with mucosal surfaces. The vast preponderance of primary infections occur following mucosal exposure to infectious virions, and the high seroprevalence of HCMV throughout the ...

CD34+ stem cells from umbilical cord blood

open access: yesClinics and Practice, 2011
We describe the relation between umbilical cord clamping time and two different enrichment system of CD34+ stem cells from umbilical cord blood with the proliferative ability and bone marrow reconstitution of the stem cells obtained.

Efficient generation of multipotent mesenchymal stem cells from umbilical cord blood in stroma-free liquid culture. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Haematopoiesis is sustained by haematopoietic (HSC) and mesenchymal stem cells (MSC). HSC are the precursors for blood cells, whereas marrow, stroma, bone, cartilage, muscle and connective tissues derive from MSC.

Further phenotypic characterization of the primitive lineage− CD34+CD38−CD90+CD45RA− hematopoietic stem cell/progenitor cell sub-population isolated from cord blood, mobilized peripheral blood and patients with chronic myelogenous leukemia

open access: yesBlood Cancer Journal, 2011
The most primitive hematopoietic stem cell (HSC)/progenitor cell (PC) population reported to date is characterized as being Lin−CD34+CD38−CD90+CD45R.

Proteogenomic characterization of cholangiocarcinoma

open access: yesHepatology, EarlyView., 2022
Proteogenomic characterization of cholangiocarcinoma with therapeutic strategies Abstract Background and Aims Cholangiocarcinoma (CCA) is a highly heterogeneous cancer with limited understanding and few effective therapeutic approaches. We aimed at providing a proteogenomic CCA characterization to inform biological processes and treatment ...

Targeting novel antigens in the arterial wall in thromboangiitis obliterans.

open access: yesFolia Histochemica et Cytobiologica, 2010
Thromboangiitis obliterans is an inflammatory disease possibly resulting from cigarette smoking as a primary etiologic factor, perhaps as a delayed type of hypersensitivity or toxic angiitis.
