EGR1 Promotes Craniofacial Bone Regeneration via Activation of ALPL⁺PDGFD⁺ Periosteal Stem Cells

open access: yesAdvanced Science, EarlyView.
ALPL+PDGFD+ (AP+) cells are distinct calvarial periosteal stem cells (PeSCs) with diminished postnatal activity. EGR1 drives PeSCs development via BMP signaling through its Znf2 domain and activates them via CTNNB1/WNT10B signaling through its Znf2/3 domains.

Presbycusis: Pathology, Signal Pathways, and Therapeutic Strategy

open access: yesAdvanced Science, EarlyView.
In ARHL, the stria vascularis, acting as a cochlear battery, gradually loses its ability to maintain the endocochlear potential, leading to impaired hair cell function and progressive hearing loss. Single‐cell sequencing reveals age‐related cellular changes in the cochlea, providing insights into the underlying mechanisms of aging and potential ...

Exome Sequencing Reveals the Genetic Architecture of Non‐syndromic Orofacial Clefts and Identifies BOC as a Novel Causal Gene

open access: yesAdvanced Science, EarlyView.
Nonsyndromic orofacial clefts (NSOFCs) are the most common craniofacial defects. Exome sequencing of 214 sporadic cases sheds new light on its genetic architecture and identifies many candidate pathogenic variants. Furthermore, functional studies establish BOC as a novel causal gene and reveal an unusual two‐locus model of inheritance via the epistatic

Structure, Mechanics, and Mechanobiology of Fibrocartilage Pericellular Matrix Mediated by Type V Collagen

open access: yesAdvanced Science, EarlyView.
This study defines the structure, mechanics, and mechanobiology of the fibrocartilage pericellular matrix (PCM) using the murine meniscus, showing how collagen V deficiency alters PCM properties and disrupts cell mechanosensitive signaling. Findings emphasize the critical role of PCM in fibrocartilage mechanobiology and suggest targeting it can enhance

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

open access: yesAdvanced 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 ...

Eosinophils‐Induced Lumican Secretion by Synovial Fibroblasts Alleviates Cartilage Degradation via the TGF‐β Pathway Mediated by Anxa1 Binding

open access: yesAdvanced Science, EarlyView.
Eosinophils play a crucial role in the progression of temporomandibular joint osteoarthritis (TMJOA). This study demonstrates that eosinophils, induced by OVA/IL‐5, promote Lumican secretion in the synovium, which binds to Annexin A1 in chondrocytes, inhibiting transforming growth factor β2 and Smad2/3 phosphorylation.

Polyphenols suppress inducible oxidative stress in human osteoarthritic and bovine chondrocytes

open access: yesOsteoarthritis and Cartilage Open, 2020
Reactive oxygen species (ROS) and nitric oxide (NO) have been implicated in chondrocyte senescence and cartilage aging, pathogenesis of osteoarthritis (OA), and rheumatoid arthritis.

Orosomucoid 1 Ameliorates Temporomandibular Joint Osteoarthritis by Maintaining Cartilage Homeostasis

open access: yesAdvanced 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.

Transdifferentiation of Fibroblast into Chondrocytes

open access: yes, 2015
Great strides have been made in generating autologous induced pluripotent stem cells (iPSCs) via the process of cellular reprogramming. A key step in cellular reprogramming is the opening of chromatin. In newer transdifferentiation schemes, instead of reverting cells all the way to the embryonic state, cells can instead be redirected to specific cell ...
