Basic fibroblast growth factor (bFGF) is known to play a critical role in tumorigenesis of solid tumors. The importance of bFGF in hematological malignancies such as acute myeloid leukemia (AML) remains to be elucidated. Therefore, we determined bFGF protein expression by immunohistochemical analyses in bone marrow biopsies of patients with newly diagnosed, untreated AML. The expression of bFGF...

Basic fibroblast growth factor (bFGF), a potent inducer of angiogenesis in vivo, stimulates the production of both urokinase- and tissue-type plasminogen activators (PAs) in cultured bovine capillary endothelial cells. The observed increase in proteolytic activity induced by bFGF was effectively diminished by picogram amounts of transforming growth factor beta (TGF beta), but could not be aboli...

Basic fibroblast growth factor (bFGF) has minimal pharmacological effects in the central nervous system in the absence of blood-brain barrier (BBB) disruption. BBB transport of bFGF occurs via an absorptive-mediated transcytosis mechanism, which is relatively inefficient. To enhance the BBB transport of bFGF, this neurotrophin was reformulated to enable receptor-mediated transport across the BB...

Basic fibroblast growth factor (bFGF) is a pleiotropic cytokine with pro-angiogenic and neurotrophic effects. The angioregulatory role of this molecule may become especially significant in retinal neovascularization, which is a hallmark of a number of ischemic eye diseases. This study was undertaken to reveal expression characteristics of bFGF, produced by retinal glial (Müller) cells, and to d...

OBJECTIVE In preparation for clinical trials of basic fibroblast growth factor (bFGF) to treat ischemic heart disease, we sought to identify a clinically feasible method of bFGF administration. BACKGROUND Basic FGF has been shown to promote collateral development after experimentally induced coronary occlusion; however, methods of bFGF delivery that have been shown to be effective in previous...

To investigate the effect of basic Fibroblast Growth Factor (bFGF) on fibrovascular ingrowth into porous polyethylene orbital implants (Medpor) and to investigate any differences according to the method of administration. For the treated groups, after evisceration and Medpor implantation, bFGF was administered by soaking Medpor in the bFGF solution, and/or by injecting bFGF into the Medpor 1 we...

Heparin-immobilized porous biodegradable scaffolds were fabricated to release basic fibroblast growth factor (bFGF) in a sustained manner. Heparin was covalently conjugated onto the surface of macroporous PLGA scaffolds fabricated by a gas-foaming/salt-leaching method. Sustained release of bFGF was successfully achieved for over 20 days due to high affinity of bFGF onto the immobilized heparin....

Chronic lymphocytic leukemia (CLL) is characterized by delayed senescence and slow accumulation of monoclonal, small lymphocytes. Basic fibroblast growth factor (bFGF) is a pleiotropic cytokine that plays a role in hematopoiesis and apoptosis. Elevated bFGF levels have been detected in urine from patients with a variety of neoplastic diseases including various leukemias; however, the cellular s...

Arteries enlarge in response to increased blood flow, but the molecular signals controlling this enlargement are not well understood. Basic fibroblast growth factor (bFGF) is a potent mitogen for endothelial cells (EC) and smooth muscle cells (SMC) and promotes cellular proliferation and differentiation. In order to determine whether bFGF is expressed in response to increased blood flow in vivo...

STUDY DESIGN Reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistological analysis of spinal cord and pain behavior analysis in a rat neuropathic pain model were conducted to examine the function of microglial basic fibroblast growth factor (bFGF) in the development of neuropathic pain. OBJECTIVE To investigate the role of bFGF in spinal microglia during the development of ...
