Journal of Cellular Physiology, 231(6), 1392-1404. https://doi.org/10.1002/jcp.25282

The transmembrane glycoprotein E11 is considered critical in early osteoblast–osteocyte transitions (osteocytogenesis), however its function and regulatory mechanisms are still unknown. Using the late osteoblast MLO-A5 cell line we reveal increased E...

The development of predictive mathematical models can contribute to a deeper understanding of the specific stages of bone mechanobiology and the process by which bone adapts to mechanical forces. The objective of this work was to predict, with spatia... Read More about Predicting cortical bone adaptation to axial loading in the mouse tibia.

BONE, 81, 277-291. https://doi.org/10.1016/j.bone.2015.07.035

PHOSPHO1 is one of principal proteins involved in initiating bone matrix mineralisation. Recent studies have found that Phospho1 KO mice (Phospho1-R74X) display multiple skeletal abnormalities with spontaneous fractures, bowed long bones, osteomalaci...

Occipital foramina development involves localised regulation of mesenchyme proliferation and is independent of apoptosis (2015)
Journal Article
Akbareian, S. E., Pitsillides, A. A., Macharia, R. G., & McGonnell, I. M. (2015). Occipital foramina development involves localised regulation of mesenchyme proliferation and is independent of apoptosis. Journal of Anatomy, 226(6), 560-574. https://doi.org/10.1111/joa.12304

Cranial foramina are holes within the skull, formed during development, allowing entry and exit of blood vessels and nerves. Once formed they must remain open, due to the vital structures they contain, i.e. optic nerves, jugular vein, carotid artery,...
