Osteoporosis is an age-related disorder characterized by bone loss and increased fracture susceptibility. Whether this is due to reduced loading in less active elderly individuals or inherent modifications in bone cells is uncertain. We suppose that...

Mineralization of bone is achieved by the sequential maturation of the immature amorphous calcium phase to mature hydroxyapatite and is central to the process of bone development and repair. To study normal and dysregulated mineralization in vitro, s... Read More about Raman spectroscopy links differentiating osteoblast matrix signatures to pro-angiogenic potential.

Propagation phase-contrast micro-computed tomography allows laboratory-based three-dimensional imaging of articular cartilage down to the cellular level (2019)
Journal Article

Osteoarthritis and Cartilage, 28, 102-111. https://doi.org/10.1016/j.joca.2019.10.007

High-resolution non-invasive three-dimensional (3D) imaging of chondrocytes in articular cartilage remains elusive. The aim of this study was to explore whether laboratory micro-computed tomography (micro-CT) permits imaging cells within articular ca...

Dchs1-Fat4 regulation of osteogenic differentiation in mouse (2019)
Journal Article

In human, mutations of the protocadherins FAT4 and DCHS1 result in Van Maldergem syndrome, which is characterised, in part, by craniofacial abnormalities. Here, we analyse the role of Dchs1-Fat4 signalling during osteoblast differentiation in mouse.... Read More about Dchs1-Fat4 regulation of osteogenic differentiation in mouse.

Regulation of the bone vascular network is sexually dimorphic (2019)
Journal Article

Osteoblast (OB) lineage cells are an important source of vascular endothelial growth factor (VEGF), which is critical for bone growth and repair. During bone development, pubertal differences in males and females exist, but little is known about whet... Read More about Regulation of the bone vascular network is sexually dimorphic.

Osteoarthritis (OA) is a global disease that, despite extensive research, has limited treatment options. Pet dogs share both an environment and lifestyle attributes with their owners, and a growing awareness is developing in the public and among rese...

American Journal of Pathology, 189(4), 753-761. https://doi.org/10.1016/j.ajpath.2018.12.007

Glucocorticoid-induced secondary osteoporosis is the most predictable side-effect of this anti-inflammatory. One of the main mechanisms by which glucocorticoids achieve such deleterious outcome in bone is by antagonizing Wnt/β-catenin signalling. Scl...
