The bone remodelling cycle [PDF]

Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 2018
The bone remodelling cycle replaces old and damaged bone and is a highly regulated, lifelong process essential for preserving bone integrity and maintaining mineral homeostasis. During the bone remodelling cycle, osteoclastic resorption is tightly coupled to osteoblastic bone formation.

3D porous architecture of stacks of β-TCP granules compared with that of trabecular bone: a microCT, vector analysis and compression study

Frontiers in Endocrinology, 2015
The 3D arrangement of porous granular biomaterials usable to fill bone defects has received little study. Granular biomaterials occupy 3D space when packed together in a manner that creates a porosity suitable for the invasion of vascular and bone cells.

Experimental study of dexamethasone-loaded hollow hydroxyapatite microspheres applied to direct pulp capping of rat molars

Frontiers in Endocrinology, 2023
BackgroundDexamethasone (DEX) exerts anti-inflammatory and osteogenic effects. Hydroxyapatite is commonly used in bone repair due to its osteoconductivity, osseointegration, and osteogenesis induction. Hollow hydroxyapatite (HHAM) is often used as a drug

Chemokines and Bone Remodeling

International Journal of Immunopathology and Pharmacology, 2008
Bone remodeling is characterized by spatial and temporal coupling of bone resorption and formation and is necessary for skeletal growth and normal bone structure maintenance. Imbalance of this process is related to metabolic bone disorders such as osteoporosis or rheumatoid arthritis.

Bone remodelling at a glance [PDF]

Journal of Cell Science, 2011
The bone remodelling cycle (see Poster panel “The bone remodelling cycle”) maintains the integrity of the skeleton through the balanced activities of its constituent cell types. These are the bone-forming osteoblast, a cell that produces the organic bone matrix and aids its mineralisation ([

Macrophages and Bone Remodeling

Journal of Bone and Mineral Research, 2023
ABSTRACT Bone remodeling in the adult skeleton facilitates the removal and replacement of damaged and old bone to maintain bone quality. Tight coordination of bone resorption and bone formation during remodeling crucially maintains skeletal mass. Increasing evidence suggests that many cell types beyond osteoclasts

Endothelialized tissue engineered 3D-construct for bone repair [PDF]

, 2005
One of the main problems arising when implanting a graft into a large bone gap is its insufficient vascularization in the central region. This results in impaired bone healing and often leads to necrosis in the graft.

The clock genes Period 2 and Cryptochrome 2 differentially balance bone formation [PDF]

, 2010
Background: Clock genes and their protein products regulate circadian rhythms in mammals but have also been implicated in various physiological processes, including bone formation.

Bone Remodeling and the Microbiome [PDF]

Cold Spring Harbor Perspectives in Medicine, 2017
Exposed surfaces of mammals are colonized with 100 trillion indigenous bacteria, fungi, and viruses, creating a diverse ecosystem known as the microbiome. The gastrointestinal tract harbors the greatest numbers of these microorganisms, which regulate human nutrition, metabolism, and immune system function.
