Abstract
The aim of the study was to construct small-diameter vascular grafts using canine mesenchymal stem cells (cMSCs) and a pulsatile flow bioreactor. cMSCs were isolated from canine bone marrow and expanded ex vivo. cMSCs were then seeded onto the luminal surface of decellularized arteri...

Abstract
We employed EPCs seeded in PCL scaffold with surface-immobilized heparin and vascular endothelial growth factor (VEGF). EPCs seeded on scaffolds with VEGF exhibited phosphorylation of the receptor. After 7 days of subcutaneous implantation in immunodeficient mice, heparin-immobilized PCL scaffolds w...

We investigated the molecular mechanism of the effects of this combination therapy on melanoma tumor growth. In B16 tumor-bearing mice, the addition of IFN-α to DTIC treatment significantly reduced tumor volume, compared with control or DTIC alone. Consistently, Digital Radiography data showed less...

Abstract
We recently reported that apolipoprotein A-I (apoA-I) and apoA-I mimetic peptides inhibit tumor growth and improve survival in a mouse model of ovarian cancer. The current study was designed to examine whether inhibition of angiogenesis is one of the mechanisms for the observed anti-tumorigenic effe...

Abstract
We describe the design, production and characterization of a novel immunocytokine, in which murine interferon-alpha2 was sequentially fused with the tumor-targeting antibody fragment scFv(F8), specific to the alternatively-spliced EDA domain of fibronectin. The resulting fusion protein (F8-IFNa) cou...

We performed a protein-protein interaction screen with the Robo4 extracellular domain. We find that Robo4 specifically binds to UNC5B, a vascular Netrin receptor, revealing unexpected interactions between two endothelial guidance receptors. We show that Robo4 maintains vessel integrity by activating...

We show that SDF-1 and VEGF, which are produced by tumors, increase Dll4 expression on recruited BM-VPC. Mechanistically, BM-VPC activated, in a Dll4-dependent manner, a transcriptional program on mature EC suggestive of EC activation and stabilization. BM-VPC induced ICAM-2 and Fibronectin expressi...

We have generated a zebrafish line carrying a stop mutation in the kinase domain of the Tie-2 receptor. Mutant embryos lack Tie-2 protein, but do not display any defect in heart and vessel development. Simultaneous loss of Tie-1 and Tie-2, however, leads to a cardiac phenotype. Our study shows that...

Abstract
We studied their expression and localization in normal subjects and in genetically characterized UCMD and BM patients. We found that localization of α5, and to a lesser extent α6, is restricted to the papillary dermis, where the protein mainly colocalizes with collagen fibrils. In addition, both c...
