The role of angiogenesis as a prognostic indicator in cancer has been extensively studied in recent times with several studies demonstrating a positive correlation for various malignant tumours. However, the role of angiogenesis in osteosarcoma remains a topic of debate. In this study, we aim to evaluate the significance of intratumoural microvessel density(More)
OBJECTIVES Epiphyseal cartilage is a barrier to osteosarcoma invasion, however the mechanisms behind this resistance remain unclear. The aim of this study was to examine the chronological and spatial patterns of osteosarcoma growth and invasion of local tissue structures including epiphyseal cartilage. METHODS We used an in vivomouse model of osteosarcoma(More)
Pigment epithelium-derived factor (PEDF) is a potent anti-angiogenic factor found in a wide range of fetal and adult tissues, where it is thought to play a role in the regulation of angiogenesis during development. The temporal expression of PEDF during endochondral bone formation has not previously been reported. In this study, we analysed the expression(More)
BACKGROUND Osteosarcoma predominantly afflicts young people in their second and third decades of life. When osteosarcoma arises in patients older than 40 years, the prognosis is usually poorer compared to their younger counterparts. Although the clinical, histopathologic features and prognostic indicators are well defined for young patients, much less is(More)
