Bone is a highly vascularized tissue, but the function of angiogenesis in bone modeling and remodeling is still poorly defined, and the molecular mechanisms that regulate angiogenesis in bone are… (More)
VEGF is crucial for metaphyseal bone vascularization. In contrast, the angiogenic factors required for vascularization of epiphyseal cartilage are unknown, although this represents a developmentally… (More)
Vascular endothelial growth factor (VEGF)-mediated angiogenesis is an important part of bone formation. To clarify the role of VEGF isoforms in endochondral bone formation, we examined long bone… (More)
Adaptation to hypoxia is a critical cellular event both in pathological settings, such as cancer and ischaemia, and in normal development and differentiation. Oxygen is thought to be not only an… (More)
Hemizygous deletion of chromosome 22q11 (del22q11) causes thymic, parathyroid, craniofacial and life-threatening cardiovascular birth defects in 1 in 4,000 infants. The del22q11 syndrome is likely… (More)
Genomic actions induced by 1alpha25-dihydroxyvitamin D(3) [1,25(OH)(2)D(3)] are crucial for normal bone metabolism, mainly because they regulate active intestinal calcium transport. To evaluate… (More)
Vascular endothelial growth factor (VEGF) and beta-catenin both act broadly in embryogenesis and adulthood, including in the skeletal and vascular systems. Increased or deregulated activity of these… (More)

To ensure a multitude of essential cellular functions, the extracellular concentration of calcium is maintained within a narrow physiological range. This depends on integrated regulation of calcium… (More)
Adequate vascularization is an absolute requirement for bone development, growth, homeostasis, and repair. Endochondral ossification during fetal skeletogenesis is typified by the initial formation… (More)
Current therapies for delayed- or nonunion bone fractures are still largely ineffective. Previous studies indicated that the VEGF homolog placental growth factor (PlGF) has a more significant role in… (More)
