Knockdown of DANCR reduces osteoclastogenesis and root resorption induced by compression force via Jagged1

Cell Cycle, 2019
LncRNA DANCR has been proven to be involved in osteoblast differentiation. This study aims to investigate the role of DANCR in osteoclast formation and root resorption in periodontal ligament (PDL) cells induced by compression force (CF). Rat orthodontic

Glucocorticoids Alter Bone Microvascular Barrier via MAPK/Connexin43 Mechanisms

Advanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
Osteoporosis induced by Glucocorticoids (GCs) is a common complication of long‐term GC use in patients with inflammatory and autoimmune conditions, often leading to an increased fracture risk. A 3D bicellular endo‐osteo microfluidic platform is developed to explore pathogenic mechanisms underlying GCs‐induced osteoporosis, highlighting a novel MAPK ...

An Animal‐Free Patient‐Derived Tissue‐Mimetic Biochip Model of the Human Synovial Membrane for Human‐Relevant Osteoarthritis Research

Advanced Healthcare Materials, EarlyView.
Reihs et al. present the development of a humanized, animal‐free synovial membrane model for osteoarthritis. Methods include 3D biochip cultures of human‐primary OA synoviocytes with matrix and serum surrogates. Results show replication of synovial architecture and increased Yap1 expression.

Cervical root resorption. [PDF]

ARS Medica Tomitana, 2013
Abstract Cervical resorption is an inflammatory-mediated external resorption of the root, which can be seen after trauma and following internal bleaching techniques. It is initiated in the periodontal ligament, but the exact pathogenesis is not known.

Use of mineral trioxide aggregrate in the non-surgical repair of perforating invasive cervical resorption [PDF]

, 2008
Mineral trioxide aggregate (MTA) has shown potential as a repair material for perforations. This clinical case demonstrates that when MTA was used as a repair material for root perforation due to invasive cervical resorption, the tooth was well in ...

Microphysiological Systems for Comorbidity Studies: Chronic Kidney Disease and Osteoarthritis

Advanced 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
