DeLeve, Laurie D., Xiangdong Wang, Margaret K. McCuskey, and Robert S. McCuskey. Rat liver endothelial cells isolated by anti-CD31 immunomagnetic separation lack fenestrae and sieve plates. Am J Physiol Gastrointest Liver Physiol 291: G1187–G1189, 2006. First published June 15, 2006; doi:10.1152/ajpgi.00229.2006.— The gold standard for the identification of sinusoidal endothelial cells (SEC) is...

Purpose: Angiogenesis is an important step in the process of cancer growth. The purpose of this study was to determine the neoangiogenesis with CD31, CD34 and CD105, and tried to observe the differences between these three antibodies. Material/Methods: The blood vessels stained with CD31, CD 34 and CD105 were counted, and we reported their number per square millimeter to obtain microvascular de...

Objectives. To evaluate the role of angiogenesis tumor marker CD31 in the detection of precancerous and cancerous cervical lesions and to compare its efficacy with colposcopy and histopathology. Materials and Methods. 230 patients with a suspicious looking cervix and an abnormal Pap smear attending the Outpatient Department of Obstetrics and Gynaecology of GSVM Medical College were subjected to...

Neovascularization provides the route for nutrient supply to the tumor and the conduit for tumor cells to be shed into the circulation. CD31 is a pan-endothelial cell marker and CD105 is an active endothelial cell marker, but whether there is a link between CD105 expression and metastasis in Hepatocellular carcinoma (HCC) still remains unclear. A tissue microarray containing 38 HCCs and adjacen...

OBJECTIVES This study was designed to evaluate whether replacing CD31 (PECAM-1) signaling can restore the regulation of lymphocyte activation and improve experimental atherosclerosis. BACKGROUND Atherosclerosis, the principal cause of myocardial infarction and stroke, is due to the development of a pathogenic immune response within the vascular wall and is aggravated by the reduction of regul...

Endothelial cells of blood vessels in tumors may be thin, fragile, and defective in barrier function. We found previously that the endothelium of vessels in human colon carcinoma xenografts in mice is a mosaic structure. Approximately 85% of tumor vessels have uniform CD31 and/or CD105 immunoreactivity, but the remainder have focal regions that lack these common endothelial markers. The present...

Insulin-like growth factor 1 (IGF-1) and hepatocyte growth factor (HGF) are two potent cell survival and regenerative factors in response to myocardial injury (MI). We hypothesized that simultaneous delivery of IGF+HGF combined with Sca-1+/CD31- cells would improve the outcome of transplantation therapy in response to the altered hostile microenvironment post MI. One million adenovirus nuclear ...

HIV-1-infected adults over the age of 50 years progress to AIDS more rapidly than adults in their twenties or thirties. In addition, HIV-1-infected individuals receiving antiretroviral therapy (ART) present with clinical diseases, such as various cancers and liver disease, more commonly seen in older uninfected adults. These observations suggest that HIV-1 infection in older persons can have de...

لایه اندومتریال رحم شامل جمعیتی از سلول ها است که خاصیت خود نوزایی داشته و ویژگی هایی شبیه سلول های بنیادی مزانشیمی را نشان می دهند. در این مطالعه هدف بررسی توان تمایزی سلول های بنیادی اندومتریال به رده های مختلف سلولی می باشد. سلول های اندومتریال از نمونه های بافتی بدست آمده از رحم انسان به صورت آنزیمی جداسازی شده و در محیط کشت dmem/f12 حاوی 10% سرم کشت داده شدند. بعد از پاساژ سوم سلول ها برای...
