Clinical and radiographic findings without the use of bone substitute materials in extraction sockets and delayed implant placement- A case series

open access: yesJournal of Oral Biology and Craniofacial Research, 2020
Aim: To observe clinically and radiographically (CBCT), the extent of bone resorption in extraction socket without the use of bone graft substitutes and delayed implant placement. Material and methods: 50 compliant patients were selected for study.

Mechanical sensing protein PIEZO1 regulates bone homeostasis via osteoblast-osteoclast crosstalk

open access: yesNature Communications, 2020
Wolff’s law and the Utah Paradigm of skeletal physiology state that bone architecture adapts to mechanical loads. These models predict the existence of a mechanostat that links strain induced by mechanical forces to skeletal remodeling.

Fluid Shear‐Controlled Pro/Anti‐Inflammatory Osteomodulatory Construct for Drug‐Free Immune Activation Through Cationic Ion Channel Activation

open access: yesAdvanced Healthcare Materials, EarlyView.
A 3D‐printed PCL scaffold coated with Arginine was laminated with electrospun polyvinyl alcohol (PVA) nanofibers containing cationic cellulose nanocrystals (PVA@cCNC). This created nanoisland‐like regions of aligned and random cCNC‐rich fibers. The composite scaffold, under fluid shear stimulation, modulated macrophage polarization from M1 to M2 ...

Microphysiological Systems for Comorbidity Studies: Chronic Kidney Disease and Osteoarthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
This review highlights the potential of organ‐on‐a‐chip systems for studying comorbidities, using chronic kidney disease (CKD) and osteoarthritis (OA) as examples. It summarizes recent advances in kidney‐on‐a‐chip and joint‐on‐a‐chip models and discusses their current and potential application in investigating CKD, OA, and CKD‐OA comorbidity, aiming to

Identification of osteoclast-osteoblast coupling factors in humans reveals links between bone and energy metabolism

open access: yesNature Communications, 2020
Anti-resorptive bone therapies also inhibit bone formation, as osteoclasts secrete factors that stimulate bone formation by osteoblasts. Here, the authors identify osteoclast-secreted factors that couple bone resorption to bone formation in healthy ...

The reversal phase of the bone-remodeling cycle: cellular prerequisites for coupling resorption and formation

open access: yesBoneKEy Reports, 2014
The reversal phase couples bone resorption to bone formation by generating an osteogenic environment at remodeling sites. The coupling mechanism remains poorly understood, despite the identification of a number of ‘coupling' osteogenic molecules.

Conditioned Media from Mechanically Stimulated Macrophages Upregulate Osteogenic Genes in Human Mesenchymal Stromal Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Bone fracture healing is a complex, timely orchestrated scenario involving multiple cell types and a plethora of cytokines and regulatory factors. To gain further insight, an in vitro model to a) study macrophage polarization under mechanical load in a fibrin hydrogel and b) subsequently assess the effect of conditioned media derived from macrophages ...

Electron Microscopic Studying of Rat Bone Cells Under Microgravity Conditions [PDF]

open access: yes, 2016
In the experiments on rats (SLS-2) with the use of electron microscopy there was made the study of the osteoclasts population and the peculiarities of resorptive processes in a spongy bone of the epiphyses and the iliac crest.The results of investigation

RACK1 interaction with c-Src is essential for osteoclast function

open access: yesExperimental and Molecular Medicine, 2019
Bone disease: scaffolding protein essential for bone resorption The interaction between RACK1, a so-called scaffolding protein that can assemble components of a signaling pathway into complexes, and c-Src, an enzyme involved in the re-organization of the
