From the dichloromethane extract of Ulex airensis three new isoflavonoids, ulexin C (1), ulexin D (2), and 7-O-methylisolupalbigenin (3), were isolated and characterized by spectroscopic methods. Ulexin D (2) was also identified from the dichloromethane extract of Ulex europaeus ssp. europaeus.
Aleuria aurantia lectin (AAL) is an L-fucose-specific lectin produced in the mycelia and fruit-bodies of the widespread ascomycete fungus Aleuria aurantia. It is extensively used in the detection of fucose, but its physiological role remains unknown. To investigate this, we analyzed the interaction
OBJECTIVE
Salvia miltiorrhiza (SM, also known as DanShen) is one of the well-known widely-used Chinese herbal medicines in clinical practice. In this study we aimed to demonstrate the pro-angiogenic effects of Salvianolic acids (SAs) to treat illnesses such as ischemic cardiovascular diseases, the
Tumor metastasis is usually a serious problem in tumor patients because of the lack of therapeutic approaches. A new compound, N-all-trans-retinoyl-L-proline (ATRP), has been developed and its metastasis inhibition activity has been studied. Low concentrations of ATRP have already been found to
We have used rhesus monkey embryonic stem (ES) cells to study endothelial cell development. Rhesus ES cells (R366.4 cell line) exposed to medium containing vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), insulin-like growth factor (IGF), and epidermal growth factor
BACKGROUND
Recent studies have suggested that bone marrow stromal cells (BMSC) have the potential to differentiate into endothelial cells. However, the physiologic functions of the endothelial-like cells derived from BMSC have not been well studied.
METHODS
Human BMSC were induced to differentiate
Nanoparticles (NP) are employed in various therapeutic approaches for innovative drug delivery strategies. Among them, there is drug delivery to the brain and sustained release forms for intravenous drug delivery. In order to optimize drug carriers and to elucidate involved mechanisms such as
We recently identified ABO(H) blood group structures in Asn-linked sugar chains of human von Willebrand factor (vWF) purified from factor VIII concentrates (J Biol Chem 267:8723, 1992). We surveyed plasma glycoproteins carrying ABO(H) blood group antigens by Western blotting analysis and sandwich
The endothelial progenitor cells (EPCs) are responsible for postnatal vasculogenesis in physiological and pathological neovascularization and have been used for attenuating ischemic diseases. However, EPCs from umbilical cord blood (CB) were not well understood and the homing mechanisms of EPCs
OBJECTIVE
To investigate the feasibility of transplanting cord blood CD133+ cells derived endothelial progenitor cells (EPC) in therapeutic vasculogenesis.
METHODS
CD133+ cells from the cord blood of 52 neonates were cultured in fibronectin-coated flask in M199 medium supplemented with 10% fetal
Circulating endothelial progenitor cells (EPCs) provide revascularisation for cardiovascular disease and the expansion of these cells opens up the possibility of their use as a cell therapy. Herein we show that interleukin-3 (IL3) strongly expands a population of human non-adherent endothelial
We have reported the production of human monoclonal antibodies (mAb), by the fusion of lymph node lymphocytes from a primary carcinoma patient with murine myeloma cells. Seven heterohybridomas showed reactivity with class III antigens, and five hybridomas (1G12, 2D4, 4H5, 5D10 and 3B10) were
Neoplastic angioendotheliomatosis is a rare disorder usually characterized by primarily cutaneous or neurological symptoms. Approximately 40 cases of malignant angioendotheliomatosis with primary central nervous system (CNS) symptoms have been reported. Some investigators have postulated a
OBJECTIVE
To determine whether mobilized peripheral blood mononuclear cells (M-PBMNCs) obtained from patients with diabetes was impaired in therapeutic neovascularization in limb ischemia, and to explore the pathological mechanisms of the impairment.
METHODS
Endothelial progenitor cells (EPC) were
BACKGROUND
Cell-based vascular therapies of endothelial progenitor cells (EPCs) mediated neovascularization is still a novel but promising approach for the treatment of ischemic disease. The present study was designed to investigate the therapeutic potentials of human umbilical cord blood-derived
