Retroperitoneal Extraskeletal Osteosarcoma without Calcification Mimicking Pancreas Tumor: CT Imaging of a Case Report

대한영상의학회지, 2018
Retroperitoneal extraskeletal osteosarcoma is a rare tumor. Typical imaging findings include a soft tissue mass accompanied with internal calcifications.

Hedgehog Signaling in Endochondral Ossification

Journal of Developmental Biology, 2016
Hedgehog (Hh) signaling plays crucial roles in the patterning and morphogenesis of various organs within the bodies of vertebrates and insects. Endochondral ossification is one of the notable developmental events in which Hh signaling acts as a master ...

An Injectable BMP‐2‐Releasing Porous Hydrogel Regulating the Paracrine Effects of ADSCs Promotes Tendon‐to‐Bone Healing in Rotator Cuff Repair

Advanced Science, EarlyView.
This study designs an injectable porous hydrogel (HMs/MBs/ADSCs) integrating hollow microspheres for sustained BMP‐2 release to enhance adipose‐derived stem cells' paracrine effect. It accelerates tendon‐bone healing in rat rotator cuff injuries via spatiotemporal regulation: early AMPK‐mediated mitochondrial protection and late TGF‐β/Smad2/3‐driven ...

Orosomucoid 1 Ameliorates Temporomandibular Joint Osteoarthritis by Maintaining Cartilage Homeostasis

Advanced Science, EarlyView.
The present study identified the key protein ORM1 through the proteomic analysis of synovial fluid samples from patients with temporomandibular joint osteoarthritis (TMJOA), and demonstrated the important role of ORM1 in maintaining cartilage homeostasis via the suppression of VIM/MAPK/MMP signalling.

Identifying Myeloid‐Derived Suppressor Cells and Lipocalin‐2 as Therapeutic Targets for Intervertebral Disc Degeneration

Advanced Science, EarlyView.
Inflammatory dysregulation drives intervertebral disc degeneration via stage‐dependent immune cellular dynamics. Single‐cell transcriptomics and genetic risk mapping revealed a shift from LCN2high myeloid‐derived suppressor cells maintaining disc repair in early stages to IL1B+ macrophage‐dominated pathology in advanced disease.

Yap/Taz transcriptional activity in endothelial cells promotes intramembranous ossification via the BMP pathway

Scientific Reports, 2016
Osteogenesis is categorized into two groups based on developmental histology, intramembranous and endochondral ossification. The role of blood vessels during endochondral ossification is well known, while their role in intramembranous ossification ...

PIEZO1‐GPX4 Axis Mediates Mechanical Stress‐Induced Vertebral Growth Plate Dysplasia via Ferroptosis Activation

Advanced Science, EarlyView.
Mechanical stress activates PIEZO1 in vertebral growth plate chondrocytes, triggering ferroptosis through direct binding and inhibition of GPX4. This axis promotes lipid peroxidation and pathological ossification, accelerating spinal deformities. Clinical and genetic evidence (Piezo1‐cKO) confirms its role in scoliosis progression.

Recapitulating endochondral ossification: a promising route to in vivo bone regeneration

Journal of Tissue Engineering and Regenerative Medicine, 2015
Despite its natural healing potential, bone is unable to regenerate sufficient tissue within critical‐sized defects, resulting in a non‐union of bone ends. As a consequence, interventions are required to replace missing, damaged or diseased bone.

Bidirectional Interaction Between the Brain and Bone in Traumatic Brain Injury

Advanced Science, EarlyView.
Traumatic brain injury (TBI) disrupts the blood–brain barrier and activates neuroimmune responses, causing metabolic disturbances and long‐term bone mass loss. Concurrent fractures accelerate healing and enhance osteogenesis but disrupt regulatory mechanisms, leading to altered bone dynamics and exacerbating neuroinflammation, complicating recovery ...

Ossification of Cranial Epidural Hematomas: A Systematic Review of Management Strategies and Presentation of an Illustrative Case

Neurotrauma Reports
The presence of a calcified or ossified chronic cranial epidural hematoma (EDH) is rare and has been described in only a few case reports in the literature.
