Basic fibroblast growth factor (bFGF) is thought to be a trophic factor for several classes of neurons. Its distribution changes in response to cortical neural injury. We have determined the effect of injury to the optic nerve on localization of bFGF in the rodent retina and visual pathways. Our observations were confirmed by using different antisera and monoclonal antibodies. While photorecept...

Vocal fold scar remains a therapeutic challenge. Basic fibroblast growth factor (bFGF) was reported to have regenerative effects for vocal fold scar, although it has the disadvantage of rapid absorption in vivo. A collagen-gelatin sponge (CGS) can compensate for the disadvantage by providing a sustained release system. The current study evaluated the efficacy of CGS combined with bFGF on vocal ...

Basic fibroblast growth factor (bFGF or FGF2) plays diverse roles in regulating cell proliferation, migration and differentiation during embryo development. In this study, the effect of bFGF on ovarian germ cell development was investigated in the embryonic chicken by in vitro and in vivo experiments. Results showed that a remarkable decrease in bFGF expression in the ovarian cortex was manifes...

We investigated possible involvement of voltage-dependent Ca(2+) channels (VDCCs) and several intracellular signaling mechanisms in multiple actions of basic fibroblast growth factor (bFGF), such as survival promotion, induction of calbindin D(28k) expression as well as acceleration of neuritic branch formation of cultured rat hippocampal neurons. Immunocytochemical staining with anti-gamma-ami...

Fibroblast growth factors (FGFs) are known to stimulate mitogenesis in a variety of non-neuronal cell types and to support the survival in vitro of many neuronal cell types. The physiological role of FGFs in the CNS is currently not known. The present study determined the distribution in the rat CNS of a prominent member of the FGF family, basic FGF (bFGF). Immunohistochemical analysis showed t...

We observed an induction of basic fibroblast growth factor (bFGF) mRNA in the rat retina after systemic administration of the alpha 2-adrenergic agonists xylazine and clonidine. A single injection of xylazine or clonidine transiently increased bFGF mRNA. Preinjection of yohimbine, an alpha 2-adrenergic antagonist, completely inhibited this increase. Higher dosage of yohimbine inhibited the base...

Both basic fibroblast growth factor (bFGF) and CC chemokine ligand 18 (CCL18) are important extracellular molecules in tumor microenvironment. However, their involvement in non-small cell lung cancer (NSCLC) has not been fully elucidated. The aim of the present study was to investigate the expression clinical significance of bFGF and CCL18 in NSCLC. Expression of bFGF and CCL18 protein was dete...

The effect of basic fibroblast growth factor (bFGF) on human breast cancer cells was studied in vitro. Exposure to bFGF resulted in significant growth inhibition, decreased DNA synthesis, and accumulation of cells in G0-G1. The IC50 for growth inhibition in MCF-7 cells was 50 pg/ml, and it was abrogated by neutralizing antibodies against bFGF. Inhibition of growth by bFGF was predominant over t...

Fibroblasts play a pivotal role in the process of cutaneous wound repair, whereas their migratory ability under diabetic conditions is markedly reduced. In this study, we investigated the effect of basic fibroblast growth factor (bFGF) on human dermal fibroblast migration in a high-glucose environment. bFGF significantly increased dermal fibroblast migration by increasing the percentage of fibr...
