There is a critical need for quantifiable models of angiogenesis in vivo, and in general, differential effects of angiogenic regulators on vascular morphology have not been measured. Because the potent angiogenic stimulators fibroblast growth factor (FGF)-2 (basic FGF) and vascular endothelial growth factor (VEGF) are reported to stimulate angiogenesis through distinct signaling pathways, we hy...

Fibroblast growth factor-2 (FGF-2) interacts with a dual receptor system consisting of tyrosine kinase receptors and heparan sulfate proteoglycans (HSPGs). In rat mammary fibroblasts, FGF-2 stimulated DNA synthesis and induced a sustained phosphorylation of p42/ 44 and of its downstream target, p90. Moreover, FGF-2 also stimulated the transient degradation of IkBa and IkBb. PD098059, a specific...

AIMS To assess fibroblast growth factor-2 (FGF-2) and vascular endothelial growth factor-B (VEGF-B) effects on flow reserve and morphological adaptation in the rabbit ischemic hind limb. METHODS Following bilateral femoral artery ligation, calf blood pressure (C(BP)), flow reserve, collateral artery numbers and capillary numbers were assessed. Treatment consisted of rabbit serum albumin (RSA)...

Fibroblast growth factors (FGFs) have mitogenic activity toward a wide variety of cells of mesenchymal, neuronal, and epithelial origin and regulate events in normal embryonic development, angiogenesis, wound repair, and neoplasia. FGF-2 is expressed in many normal adult tissues and can regulate migration and replication of intestinal epithelial cells in culture. However, little is known about ...

The telencephalon is formed in the most anterior part of the central nervous system (CNS) and is organised into ventral subpallial and dorsal pallial domains. In mice, it has been demonstrated that Fgf signalling has an important role in induction and patterning of the telencephalon. However, the precise role of Fgf signalling is still unclear, owing to overlapping functions of Fgf family genes...

Basic fibroblast growth factor (FGF) is synthesized as a phosphoprotein by both bovine capillary endothelial and human hepatoma cells in culture. Because basic FGF is characterized by its high affinity for heparin and its association in vivo with the extracellular matrix, we examined the possibility that the phosphorylation of this growth factor by purified protein kinase C (PK-C) and the catal...

PURPOSE Fibroblast growth factor 2 (FGF-2) is not only a potent mitogen, it is a modulator for corneal endothelial cells. To define how the modulation activities of FGF-2 are mediated, we used pharmacologic inhibitors to examine the association of phospholipase C-gamma 1 (PLC-gamma) with FGF receptor or with cytoskeleton. METHODS Cell proliferation was determined either by the incorporation o...

BACKGROUND The wide range of fresh gas flow - vaporizer setting (FGF - FD) combinations used by different anesthesiologists during the wash-in period of inhaled anesthetics indicates that the selection of FGF and FD is based on habit and personal experience. An empirical model could rationalize FGF - FD selection during wash-in. METHODS During model derivation, 50 ASA PS I-II patients receive...

Acidic and basic fibroblast growth factors (FGF) were identified in bovine cheese whey after partial purification using a two step procedure. Cation-exchange chromatography produced a mitogen-rich extract which was loaded on to a heparin-sepharose column and eluted stepwise with 0.8, 1.2 and 2.0 M-NH4HCO3. Mitogenic activity was found in all three fractions by cell growth assays using Balb/c-3T...

The FGF-4 (fibroblast growth factor 4, known as HST-1) protein is an important mitogen for a variety of cell types. However, only limited information is available concerning tissue distribution and the biological role of FGF-4 in the brain. In situ hybridization analysis revealed localization of mouse Fgf-4 mRNA in the normal postnatal mouse hippocampus, subventricular zone (SVZ), and the rostr...
