Terminal alpha (1,3) galactosyl galactoside epitopes (alpha-gal) on membrane glycoproteins expressed by vascular endothelial cells represent the major xenoreactive antigens in pig to primate xenotransplantation. In other discordant xenotransplantation combinations, such as from guinea pig to rat,
Normal human colonic microvascular endothelial cells (HUCMEC) have been isolated from surgical specimens by their adherence to Ulex europaeus agglutinin bound to magnetic dynabeads that bind alpha-L-fucosyl residues on the endothelial cell membrane. Immunocytochemistry demonstrated the presence of a
The circular dichroism (CD) spectra of lectins from Dolichos biflorus, Helix pomatia, Lotus tetragonolobus, Phaseolus vulgaris (erythroagglutinin), Pisum sativum, Sophora japonica, and Ulex europaeus I were analyzed, before and after the conformational transitions which were effected by sodium
The binding of the fucose-specific lectin, Ulex europaeus agglutinin (UEA-I), to entero-endocrine cells was studied in the ileum and caecum of humans, rabbits, rats, and mice. In all species investigated, numerous cells scattered in the crypt and villus epithelia intensely bound the UEA-I lectin.
Endothelial colony-forming cells (ECFCs) are a population of endothelial progenitor cells (EPCs) that display robust proliferative potential and vessel-forming capability. Previous studies have demonstrated that a limited number of ECFCs may be obtained from adult bone marrow, peripheral blood and
Enteroendocrine cells are solitary epithelial cells scattered throughout the gastrointestinal tract and produce various types of hormones, constituting one of the largest endocrine systems in the body. The study of these rare epithelial cells has been hampered by the difficulty in isolating them
We earlier reported that Fischer 344/jcl strain (F344) rats carrying a unique pX gene of human T lymphocyte virus type I (HTLV-I) under control of a rat lymphocyte-specific protein tyrosine kinase (p56lck) type I promoter (lck-pX rats) spontaneously developed epithelial thymomas from the thymic
In vitro primary cultures of microvascular endothelial cells from endocrine pancreas are difficult to obtain, but can be a very helpful tool for studies of islet biology, transplantation and regenerative medicine.
We applied a protocol recently described for the isolation and culture of brain
A novel human endothelial cell line, AS-M, has been established from a cutaneous angiosarcoma on the scalp. The cells expressing platelet endothelial cell adhesion molecule-1 (CD31) were isolated using magnetic beads and subsequently cultured for a year. To date, the cells have undergone more than
BACKGROUND
Endothelial progenitor cells (EPCs) provide paracrine support to the vascular endothelium and may also replace damaged or senescent endothelial cells. Low numbers of endothelial progenitor colony-forming units (CFU-ECs) in culture are a predictive biomarker of vascular disease. We
Galectin-1 is known to be one of the extracellular matrix proteins. To elucidate the biological roles of galectin-1 in cell adhesion and invasion of human anaplastic large cell lymphoma, we performed cell adhesion and invasion assays using the anaplastic large cell lymphoma cell line H-ALCL, which
