To increase our understanding of the potential role of basic fibroblast growth factor (bFGF) in malignant progression of prostate cancer, we determined the production of bFGF, the expression of FGF receptor (flg), and the response to exogenous bFGF in LNCaP, DU 145, and PC 3 cells. We observed that these three prostate cancer cell lines, which differed in their dependence on androgens for growt...

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...

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...

The three-dimensional structure of human basic fibroblast growth factor (bFGF) has been determined by x-ray crystallography and refined to a crystallographic residual of 17.4% at 2.2-A resolution. The structure was initially solved at a nominal resolution of 2.8 A by multiple isomorphous replacement using three heavy-atom derivatives. Although the map clearly showed the overall fold of the mole...

Osteonectin (secreted protein acidic and rich in cysteine, 40-kDa basement membrane) is a glycoprotein abundantly expressed in bone and in other tissues undergoing active remodeling. Fibroblast growth factors (FGFs) are important in skeletal development and fracture repair, events associated with extracellular matrix remodeling. We used the murine osteoblastic cell line MC3T3 to determine wheth...

This report describes favorable outcomes in 9 patients with skin avulsion injuries of the extremities who underwent full-thickness skin grafting and basic fibroblast growth factor (bFGF) application. Following removal of contaminated subcutaneous fat tissue on the inside of skin, the avulsed skin was processed into a full-thickness skin graft, with as much of the skin used as possible irrespect...

Basic fibroblast growth factor (bFGF) may act to modulate hematopoiesis in addition to its effects on mesenchymal cells. We studied the effects of bFGF on human and murine primary marrow megakaryocytes. bFGF modestly enhanced the size of the human megakaryocyte colony-forming unit (CFU-MK) and cell numbers per colony, in combination with interleukin-3 (IL-3) or granulocyte-macrophage colony sti...

Cultured monolayers of bovine pituitary follicular cells, which transport ions, contain high amounts of mitogenic activity for endothelial cells which, on the basis of gene expression analysis, heparin-Sepharose elution profile, bioassay, immunoblotting, radioimmunoassay, and radioreceptor assay, has been identified as basic fibroblast growth factor (bFGF). These data indicate that follicular c...
