objective: in this investigation murine embryonic stem (es) cells were differentiated into endothelial cells. materials and methods: murine es cells (cce cell line) exposed to alpha-mem medium containing 10% fbs for 4 days. then obtained flk-1 (flk-1: vascular endothelial growth factor receptor 2) positive cells were cultuted in endothelial growth medium-2 (egm-2) until the last day of experime...

objective: immunotoxins (its) have been developed for the treatment of cancer, and comprise of antibodies linked to toxins. also vascular endothelial growth factor (vegf) plays a key role in tumor angiogenesis, and the blockade of vegf receptor-2 (vegfr2) inhibits angiogenesis and tumor growth. the aim of this study was to produce anti-vegfr2/rpe (pseudomonas exotoxin) 38 it to test its cytotox...

Circulating endothelial cells (CECs) are a reliable biomarker for cardiovascular diseases (CVDs). A major unresolved challenge limiting the widespread use of CECs diagnosis and monitoring CVDs is their unreliable detection. This problem mainly attributed to low sample volume (5–10 mL) commonly used ex vivo CEC isolation methods. To overcome this limitation, BMProbe in proposed. It consists twis...

Background: Radiation-induced molecular changes on the endothelial surface of brain arteriovenous malformations (AVM) may be used as markers for specific vascular targeting agents. In this study, we examined the level of expression of platelet endothelial cell adhesion molecule-1 (PECAM-1) on brain endothelial cell surface after radiation treatment, with the aim of targeting the radiation-induc...

Despite considerable progress in the design of multifunctionalized nanoparticles (NPs) that selectively target specific cell types, their systemic application often results unwanted liver accumulation. The exact mechanisms for this general observation are still unclear. Here we asked whether number cell-targeting antibodies per NP determines extent accumulation and also addressed by which antib...

Angiostatin blocks tumor angiogenesis in vivo, almost certainly through its demonstrated ability to block endothelial cell migration and proliferation. Although the mechanism of angiostatin action remains unknown, identification of F(1)-F(O) ATP synthase as the major angiostatin-binding site on the endothelial cell surface suggests that ATP metabolism may play a role in the angiostatin response...

littoral cell angioma is a splenic vascular tumor of splenic sinus lining cells that is considered benign in general. this report describes a case of littoral cell angioma with no malignant histological features. the lesion is composed of anastomosing vascular channels resembling splenic sinus; they are lined by endothelial cells which show mitotic activity very rare. immunohistochemically, the...

introduction: human adipose-derived mesenchymal stem cells (hadscs) are easily accessible in the body, and under appropriate conditions, they can be directed toward various phenotypes. therefore, hadscs have been considered as a potential cell source for tissue engineering applications. hadscs are able to differentiate into endothelial cells which covers the interior surface of vessels, in vivo...

We have previously described a series of monoclonal antibodies against platelet membrane glycoproteins. Two of the antibodies, B59.2 and B2.12, recognize the glycoprotein IIb-IIIa complex. These two antibodies react specifically with glycoprotein (GP) IIIa, as shown by immunoblotting of sodium dodecyl sulfate-polyacrylamide gels of solubilized platelet membranes. Monoclonal B2.12, but not B59.2...
