Background: Basic fibroblast growth factor (bFGF) is a glycoprotein with stimulating ability of angiogenesis. In addition, bFGF plays an important role in wound healing process in some tissues for example gastrointestinal tract, but its ability for discrimination of various stages of wound severity in these diseases was not reported. Therefore, we aimed to determine the bFGF levels in gastric u...

Basic fibroblast growth factor (bFGF)-loaded liposome (bFGF-lip) combined with ultrasound-targeted microbubble destruction (UTMD) technique was investigated to prevent diabetic cardiomyopathy (DCM). Cardiac function and myocardial ultrastructure were assessed. Terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick-end labeling (TUNEL) staining, immunohistochemistry staining, and Western...

Basic fibroblast growth factor (bFGF) was radiolabeled and used in axonal transport studies to determine whether certain neuronal populations express functional receptors for bFGF. Unlike 125I-NGF, 125I-bFGF was not retrogradely transported in the adult rat sciatic nerve or from iris to trigeminal ganglion or superior cervical ganglion. However, after intraocular injection of 125I-bFGF into the...

To study possible functional differences of the 18-kD and high molecular weight forms of basic fibroblast growth factor (bFGF), we have examined the effect of endogenous production of different bFGF forms on the phenotype of NIH 3T3 cells. Cells transfected with cDNAs coding for either 18-kD bFGF (18-kD bFGF) or all four molecular forms (18, 22, 22.5, 24 kD; wild type [WT] bFGF) exhibit increas...

When NIH 3T3 cells were transfected with the cDNA for basic fibroblast growth factor (bFGF), most cells displayed a transformed phenotype. Acquisition of a transformed phenotype was correlated with the expression of high levels of bFGF (Quarto et al., 1989). Cells that had been transformed as a result of transfection with bFGF cDNA had a decreased capacity to bind 125I-bFGF to high affinity rec...

The present study characterizes whether basic fibroblast growth factor (bFGF) is present and released from astroglia, microglia, and hippocampal neurons in vitro. For cell content, bFGF-like immunoreactivity (IR) of cell extracts was measured, whereas release was determined by assessing the levels of bFGF-like IR in media. In addition, the effects of lymphokines and trophic factors that are kno...

Background Fertility preservation is an important part of scientific study in the field of reproductive medicine. Ovarian cryopreservation and in vitro follicles culture provide option for fertility conservation in older women or cancer patients. Basic fibroblast growth factor (bFGF) or FGF-2, is member of fibroblast growth factors family which play critical roles in cell migration proliferatio...

Basic fibroblast growth factor (bFGF or FGF-2) is abnormally elevated in the serum and urine of patients with many types of cancer. However, the source of the bFGF is unclear. We developed a model that could distin guish between tumor-derived and host-derived bFGF. We gave athymic mice s.c. injections of cells of the murine K1000 tumor, which secretes a bFGF mutein (bFGF CS23) as its dominant a...

Mesangial injury and cell proliferation are frequent findings in various glomerular diseases in man. Previous studies have demonstrated that basic fibroblast growth factor (bFGF) is a potent mesangial cell mitogen in vitro. To further elucidate the role of bFGF in rat mesangial cell (RMC) proliferation, we examined whether RMC synthesize bFGF in vitro and whether bFGF is involved in mesangial p...
