Neurotrophic factors can promote the proliferation and differentiation of neural stem cells (NSCs). Here we report that the possibility of using bFGF in combination with BDNF and NGF to promote proliferation and differentiation of NSCs in vitro. C57BL/6 mouse NSCs were cultured, passaged and stained by immunofluorescence for nestin and GFP. According to different neurotrophic factors added to N...

We have found that the spontaneous migration of bovine aortic endothelial cells from the edge of a denuded area in a confluent monolayer is dependent upon the release of endogenous basic fibroblast growth factor (bFGF). Cell movement is blocked by purified polyclonal rabbit IgG to bFGF as well as affinity purified anti-bFGF IgG and anti-bFGF F(ab')2 fragments. The inhibitory effect of the immun...

Basic fibroblast growth factor (bFGF) and its specific receptors have diverse roles on a variety of cell types, such as the induction of vascular smooth-muscle cell proliferation which contributes to restenosis after coronary balloon angioplasty. bFGF is also known to interact with heparan sulphate proteoglycans present on the cell surface or in the extracellular matrix. In this study, the bind...

OBJECTIVE The distribution and production of basic fibroblast growth factor (bFGF) was examined on the synovium from patients with rheumatoid arthritis (RA) and osteoarthritis (OA). METHODS The localisation of bFGF was determined by an immunohistochemical staining procedure using anti-bFGF monoclonal antibody. The expression of bFGF mRNA was detected by nonradioactive in situ hybridisation us...

The proteoglycan form of macrophage colony-stimulating factor (PG-M-CSF), but not M-CSF with a molecular weight of 85 kD (85-kD M-CSF), bound to immobilized basic fibroblast growth factor (bFGF), and, conversely, bFGF bound to immobilized PG-M-CSF, but not to the 85-kD M-CSF. PG-M-CSF has an additional amino acid sequence at its carboxyl terminus (part of a precursor sequence that is removed in...

OBJECTIVE Intraplaque neovascularization and hemorrhage may facilitate plaque progression. We studied expression of basic fibroblast growth factor (bFGF), a potent angiogenic mediator, by mast cells (MCs) in human coronary plaques with increasing degrees of atherosclerosis. METHODS AND RESULTS Normal and atherosclerotic coronary segments were collected from 30 autopsied subjects. Immunohistoc...

BACKGROUND UV-B-exposed keratinocytes secrete various paracrine factors. Among these factors, basic fibroblast growth factor (bFGF) stimulates the proliferation of melanocytes. Ginsenosides, the major active compounds of ginseng, are known to have broad pharmacological effects. In this study, we examined the antiproliferative effects of ginsenosides on bFGF-induced melanocyte proliferation. M...

Many different culture systems have been developed for expanding human pluripotent stem cells (hESCs and hiPSCs). In general, 4-10 ng/ml of bFGF is supplemented in culture media in feeder-dependent systems regardless of feeder cell types, whereas in feeder-free systems, up to 100 ng/ml of bFGF is required for maintaining long-term culture on various substrates. The amount of bFGF required in na...

Fibronectin (Fn) is involved in early stages of bone formation and basic fibroblast growth factor (bFGF) is an important factor regulating osteogenesis. We here found that bFGF enhanced extracellular assembly from either endogenously released or exogenously applied soluble Fn in primary cultured osteoblasts. bFGF increased protein levels of Fn using Western blotting analysis. Protein kinase C (...

The study demonstrates that basic fibroblast growth factor (bFGF) serves as an inducer of radiation damage repair in bovine aortic endothelial cells (BAEC). Radiation dose-survival curves were generated with plateau-phase BAEC using culture dishes precoated with HR9-bFGF/ extracellular matrix (ECM) for the postradiation colony formation assay. This natural basement membrane-like ECM is enriched...
