A chondrosarcoma is a common, primary malignant bone tumor that can grow to destroy the bone, produce fractures and develop soft tissue masses. Left untreated, chondrosarcomas metastasize through the vascular system to the lungs and ultimately lead to large metastatic deposits of the malignant cartilage taking over lung volume and function. Vascular endothelial growth factor (VEGF)-C has been i...

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...

Autophagy is involved in the development and/or progression of many diseases, including myocardial ischemia/reperfusion (I/R). In this study, we hypothesized a protective role of basic fibroblast growth factor (bFGF) both in vivo and in vitro and demonstrated that excessive autophagy and ubiquitinated protein accumulation is involved in the myocardial I/R model. Our results showed that bFGF imp...

BACKGROUND AIMS Recently, it has been found that effective periodontal regeneration can be induced by bone marrow mesenchymal stromal cell (BMSC) transplantation or local application of basic fibroblast growth factor (bFGF). The aim of the present study was to assess, in dogs, the efficacy of periodontal regeneration via the delivery of BMSC transfected with bFGF to repair destruction of period...

Plasminogen activator inhibitor-1 (PAI-1) inhibits fibrinolysis and proteolysis. Basic fibroblast growth factor (bFGF) stimulates angiogenesis, which requires regional proteolysis. Because modulation of vasculopathy requires tight control of proteolysis, effects of bFGF on PAI-1 expression in endothelial cells (ECs) were characterized. bFGF increased PAI-1 mRNA and accumulation of PAI-1 protein...

De novo adipogenesis at the implanted site of a basement membrane extract (Matrigel) was induced through controlled release of basic fibroblast growth factor (bFGF). bFGF was incorporated into biodegradable gelatin microspheres for its controlled release. When the mixture of Matrigel and bFGF-incorporated gelatin microspheres was implanted subcutaneously into the back of mice, a clearly visible...

Basic fibroblast growth factor (bFGF) regulates skin wound healing; however, the underlying mechanism remains to be defined. In the present study, we determined the effects of bFGF on the regulation of cell growth as well as collagen and fibronectin expression in fibroblasts from normal human skin and from hypertrophic scars. We then explored the involvement of mitochondria in mediating bFGF-in...

OBJECTIVE One of the major obstacles to ovarian tissue preservation is delayed angiogenesis that leads follicles lost after transplantation. The aim of the present study was to investigate the effects of bFGF and VEGF on heterotopic transplanted ovarian tissue using a mouse model. METHODS Female mice underwent bilateral ovariectomy. Ovarian tissues encapsulated by fibrin hydrogels were transp...

Basic fibroblast growth factor (bFGF) is a potent trophic factor for neurons and astrocytes and recently has been implicated in the pathology of Alzheimer's disease. In order to better understand the role of bFGF in normal brain function and during pathology, we have analyzed its anatomical distribution and its response to injury in the CNS. Double-staining immunohistochemistry showed that bFGF...

Basic fibroblast growth factor (bFGF, FGF-2) is one of the potent mitogens for periodontal ligament (PDL) cells. However, the role of bFGF on the matrix metalloproteinase (MMP) -3 expression in PDL cells is unknown. In this study, the effect of bFGF on MMP-3 expression in PDL cells and the mechanism of this process were examined. Human PDL cells were exposed to bFGF at various concentrations (0...
