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

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

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

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 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.

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
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 ...
