During kidney organogenesis the development of renal vessels must be synchronized with the maturation of nephrons and the collecting duct system. Several reports showed that hormones and mitogenic peptides as basic fibroblast growth factor (bFGF) or vascular endothelial growth factor (VEGF) are involved in this regulatory process. It is a known fact that bFGF receptors are expressed by differen...

Basic fibroblast growth factor (bFGF) stimulates angiogenesis and induces neural cell regeneration. We investigated the effects of bFGF on diabetic neuropathy in streptozotocin-induced diabetic rats. Diabetic rats were treated with human recombinant bFGF as follows: 1) intravenous administration, 2) intramuscular injection into thigh and soleus muscles with cross-linked gelatin hydrogel (CGH), ...

Two monoclonal antibodies (mAbs) against bovine heparin-binding growth factor II (HBGF-II)/basic fibroblast growth factor (bFGF) were obtained from mouse hybridoma cell lines. They were highly specific for bFGF from bovine, human, and mouse sources and did not cross-react with bovine heparin-binding growth factor I (HBGF-I)/acidic fibroblast growth factor (aFGF). The immunoglobulin class and su...

Basic fibroblast growth factor (bFGF) has been previously shown to be mitogenic for vascular smooth muscle cells (VSMCs) in vivo, but only after vascular injury. We show in the present study that the regulation of bFGF-stimulated VSMC proliferation, by vascular cell-secreted heparin-like compounds, correlates with inhibition of bFGF binding to cell-associated heparin sulfate proteoglycans. The ...

Several studies have demonstrated that basic fibroblast growth factor (bFGF) can induce neural differentiation of mesenchymal stem cells. In this study, we investigated the neural differentiation of muscle-derived stem cells (MDSCs) following treatment with bFGF and ethosuximide, a small molecule used as an anticonvulsant in humans. Stem cells isolated from rat skeletal muscle (rMDSCs) were pre...

Basic fibroblast growth factor (bFGF) is a polypeptide that is mitogenic for a wide variety of cell types. We used Northern blot analysis and immunohistochemistry to determine if bFGF is expressed in the nasal polyp tissue; bFGF messenger RNA was detectable in the polyps examined by Northern blot analysis. Strong immunostaining for bFGF was found in blood vessels and along the basement membrane...

mRNA for basic Fibroblast Growth Factor (bFGF) was expressed in a series of SV40-transformed human mammary cell lines as molecules of 7.1, 3.6, 2.0 and 1.2 kb. This expression was much weaker in those lines of epithelial morphology than in myoepithelial-like cell lines derived from them. It was confirmed, using northern hybridization to single-stranded RNA probes, that the multiple mRNAs were t...

A 6.75-kilobase human hepatoma-derived basic fibroblast growth factor (bFGF) cDNA was cloned and sequenced. An amino-terminal sequence generated from a purified hepatoma bFGF was found to correspond to the nucleotide sequence and to begin 8 amino acids upstream from the putative methionine start codon thought to initiate a 154-amino acid bFGF translation product. This sequence suggests that a f...

Clinical and histopathological factors fail to adequately predict outcomes in children with high-grade gliomas, indicating a need to identify relevant biological markers of tumor behavior to guide therapeutic decision-making. Basic fibroblast growth factor (bFGF) is a mitogenic and angiogenic factor that has been observed to be overexpressed in a significant percentage of malignant gliomas, alt...

The interphotoreceptor matrix (IPM) occupies the extracellular space between the photoreceptors of the retina and the apical surface of the retinal pigmented epithelium. A large proportion of the IPM is composed of aqueous-insoluble glycoconjugates, including chondroitin sulfate-containing proteoglycans, the distribution of which exhibits both apical-basal and photoreceptor cell type-specific h...
