A unique family of endothelial cell polypeptide mitogens: the antigenic and receptor cross-reactivity of bovine endothelial cell growth factor, brain-derived acidic fibroblast growth factor, and eye-derived growth factor-II
نویسندگان
چکیده
Bovine brain, hypothalamus, pituitary, and retina contain potent anionic polypeptide mitogens for endothelial cells. Immunological assays using murine monoclonal antibodies against bovine endothelial cell growth factor (ECGF) and radioreceptor assays using [125I]ECGF were performed to determine the cross-reactivity of ECGF with bovine acidic pI brain-derived fibroblast growth factor (acidic FGF) and bovine eye-derived growth factor-II [EDGF-II). We observed that acidic FGF and EDGF-II are recognized by anti-ECGF monoclonal antibodies and compete with [125I] ECGF for receptor occupancy. Furthermore, the biological activity of ECGF, acidic FGF, and EDGF-II is potentiated by the glycosaminoglycan, heparin. These results argue that ECGF, acidic FGF, and EDGF-II belong to a common family of polypeptide growth factors.

متن کاملPure brain-derived acidic fibroblast growth factor is a potent angiogenic vascular endothelial cell mitogen with sequence homology to interleukin 1.
Pure bovine brain-derived acidic fibroblast growth factor is a very potent mitogen for vascular endothelial cells in culture and, in the presence of heparin, induces blood vessel growth in vivo. Partial amino acid sequence determinations confirm that this mitogen is a unique protein having amino acid sequence homology with human interleukin 1.
متن کامل3D study of capillary network derived from human cord blood mesenchymal stem cells and differentiated into endothelial cell with VEGFR2 protein expression
New blood forming vessels are produced by differentiation of mesodermal precursor cells to angioblasts that become endothelial cells (ECs) which in turn give rise to primitive capillary network. Human cord blood (HCB) contains large subsets of mononuclear cells (MNCs) that can be differentiated into endothelial-like cells in vitro. Human mononuclear progenitor cells were purified from fresh umb...

The cDNA encoding human alpha-endothelial cell growth factor (alpha-ECGF) has been engineered for high-level expression in Escherichia coli. Induction of bacterial cultures harboring the recombinant plasmid pMJ26 results in the appearance of a prominent 16-kDa polypeptide. This protein has been purified from bacterial lysates using a rapid, 2-step procedure employing heparin-Sepharose affinity ...

Objective(s): Lung cancer is the main leading cause of cancer death worldwide. Angiogenesis is the main step in proliferation and spreading of tumor cells. Targeting vascular endothelial growth factor (VEGF) is an effective approach for inhibition of cancer angiogenesis. Nanobodies (NBs) are a novel class of antibodies derived from the camel. Unique characteristics of Nbs like their small size ...
