SMAD1/5 signaling in osteoclasts regulates bone formation via coupling factors. [PDF]

open access: yesPLoS ONE, 2018
Bone remodeling occurs via coupling between bone resorption by osteoclasts and bone formation by osteoblasts. The mechanisms that regulate osteoclast signals to osteoblasts are not well understood.

Studies on Bone-mass Formation within a Theoretical Model [PDF]

open access: yesIOSR Journal of Pharmacy and Biological Sciences, Volume 9, Issue 4 Ver. II (Jul - Aug 2014), PP 07-20, 2019
Bone-mass formation in human is looked at to understand the underlying dynamics with an eye on healing of bone-fracture and non-unions in non-invasive pathways. Three biological cells osteoblasts, osteoclasts and osteocytes are important players in creating new bone or osseous matter in which quite a few hormones, proteins and minerals have ...

Staphylococcus aureus Infects Osteoclasts and Replicates Intracellularly

open access: yesmBio, 2019
The inflammation of bone tissue is called osteomyelitis, and most cases are caused by an infection with the bacterium Staphylococcus aureus. To date, the bone-building cells, osteoblasts, have been implicated in the progression of these infections, but ...

The Sealing Zone in Osteoclasts: A Self-Organized Structure on the Bone

open access: yesInternational Journal of Molecular Sciences, 2018
Osteoclasts form a specialized cell–matrix adhesion structure, known as the “sealing zone”, during bone resorption. The sealing zone is a dynamic actin-rich structure that defines the resorption area of the bone.

Comparative transcriptomic analysis identifies distinct molecular signatures and regulatory networks of chondroclasts and osteoclasts

open access: yesArthritis Research & Therapy, 2020
Background Chondroclasts and osteoclasts have been previously identified as the cells capable of resorbing mineralized cartilage and bone matrices, respectively.

The influence of bone surface availability in bone remodelling - A mathematical model including coupled geometrical and biomechanical regulations of bone cells [PDF]

open access: yesEng Struct (2013) 47:134-147, 2012
Bone is a biomaterial undergoing continuous renewal. The renewal process is known as bone remodelling and is operated by bone-resorbing cells (osteoclasts) and bone-forming cells (osteoblasts). Both biochemical and biomechanical regulatory mechanisms have been identified in the interaction between osteoclasts and osteoblasts.

An $\textit{in vivo}$ comparison study between strontium nanoparticles and rhBMP2 [PDF]

open access: yesFrontiers in Bioengineering and Biotechnology 2020;8:499, 2020
The osteoinductive property of strontium was repeatedly proven in the last decades. Compelling $\textit{in vitro}$ data demonstrated that strontium hydroxyapatite nanoparticles exert a dual action, by promoting osteoblasts-driven matrix secretion and inhibiting osteoclasts-driven matrix resorption. Recombinant human bone morphogenetic protein 2 (rhBMP2)

Regulation of Osteoclast Differentiation by Myosin X

open access: yesScientific Reports, 2017
Osteoclasts begin as mononuclear cells that fuse to form multinuclear cells able to resorb bone. The mechanisms that regulate all the steps of osteoclast differentiation are not entirely known.

p38α MAPK regulates proliferation and differentiation of osteoclast progenitors and bone remodeling in an aging-dependent manner. [PDF]

open access: yes, 2017
Bone mass is determined by the balance between bone formation, carried out by mesenchymal stem cell-derived osteoblasts, and bone resorption, carried out by monocyte-derived osteoclasts.

Bone refilling in cortical bone multicellular units: Insights into tetracycline double labelling from a computational model [PDF]

open access: yesBiomech Model Mechanobiol (2014) 13:185-203, 2012
Bone remodelling is carried out by `bone multicellular units' (BMUs) in which active osteoclasts and active osteoblasts are spatially and temporally coupled. The refilling of new bone by osteoblasts towards the back of the BMU occurs at a rate that depends both on the number of osteoblasts and on their secretory activity.
