Relationship between bridging and dimensions of sella turcica with classification of craniofacial skeleton [PDF]

open access: yes, 2018
Purpose: In orthodontics, it is essential to determine the craniofacial skeleton pattern (class I, II, III) for planning treatment. Sella turcica bridging that is seen on lateral cephalometric radiographs is considered as a normal finding.

FGF9–FGFR2 Signaling via Osteocytes‐Preosteoblasts Crosstalks to Mediate Mechanotransduction‐Driven Intramembranous Osteogenesis in the Underdeveloped Maxilla

open access: yesAdvanced Science, EarlyView.
This study identifies osteocyte‐derived FGF9 as a mechanosensitive factor that impairs osteogenesis in the underdeveloped maxilla by inducing FGFR2 nuclear translocation in preosteoblasts. Mechanical stimulation reduces FGF9 secretion, relieving its inhibitory effect. These findings reveal a novel osteocyte–preosteoblast FGF9–FGFR2 axis in craniofacial

A Novel Therapeutic Strategy for Bone Marrow Failure: Niche Rejuvenation Using Costal Cartilage‐Derived Stem Cells

open access: yesAdvanced Science, EarlyView.
CDSCs exhibit the potential to differentiate into endothelial cells, vascular pericytes, and osteoblasts. These differentiated cells are capable of secreting additional pro‐hematopoietic cytokines. Furthermore, CDSCs can inhibit apoptosis and reduce DNA damage in injured hematopoietic stem and progenitor cells (HSPCs, including RHSCs and RHPCs), while ...

Decreased levels of insulin-like growth factor-1 and vascular endothelial growth factor relevant to the ossification disturbance in femoral heads spontaneous hypertensive rats. [PDF]

open access: yes, 2006
Ossification disturbance in femoral head reportedly is seen in the Spontaneously Hypertensive rats (SHR) between ages of 10 and 20 weeks. We investigated serum and tissue levels of insulin-like growth factor-1 (IGF-1) and vascular endothelial growth ...

Multimodal Imaging Reveals Cerebral Microcirculation Dynamics and Mechanisms in Mouse Central Nervous System After Intranasal Infection With Recombinant Pseudorabies Virus

open access: yesAdvanced Science, EarlyView.
Multi‐modality imaging strategy applied to PRV‐induced central nervous system infection enables dynamic visualization of cerebrovascular dysfunction, including hyperemia, hypoperfusion, and vascular remodeling. These changes are linked to microglial activation and impaired angiogenesis, providing mechanistic insight into PRV neuropathogenesis and ...

Effectiveness of 3D visualization technologies in planning and performing reconstructive plastic surgeries in patients with elbow contractures caused by ossification [PDF]

open access: yesTravmatologiâ i Ortopediâ Rossii
Background. Open reconstructive plastic surgeries are the most radical method of treating patients with elbow contractures caused by ossification. However, these surgeries pose a serious problem due to the large number of unsatisfactory results.

Centimeter‐Scale Self‐Assembling Tendon Organoids Drive Tissue Regeneration

open access: yesAdvanced Science, EarlyView.
Centimeter‐scale tendon organoids are engineered by mimicking the extracellular matrix and optimizing chemical cues to guide tendon stem/progenitor cells. These large, self‐assembling constructs overcome conventional size limitations and exhibit enhanced tenogenic differentiation, extracellular matrix production, and mechanical resilience. Their tissue‐

The importance of markers of osteolysis and osteogenesis in the pathogenesis of cephalohematoma in newborns

open access: yesActa Biomedica Scientifica
Background. Of particular importance in the repair process for cephalohematomas is the pathological remodeling of the bones of the cranial vault. Local changes in the bones of the skull are accompanied by the processes of osteolysis and osteogenesis and ...

The Sirt1‐Piezo1 Axis Promotes Bone Formation and Repair in Mice

open access: yesAdvanced Science, EarlyView.
Piezo1 upregulates in cartilage callus during bone repair, where its deletion impairs ossification and healing in mice, while activation enhances these processes. Sirt1 positively regulates Piezo1 expression and activity to promote osteogenesis and bone repair in mice.

MSC Membrane‐Coated circPROSC‐siRNA Nanoparticles for Ameliorating Craniosynostosis by Inhibiting Premature Suture Ossification

open access: yesAdvanced Science, EarlyView.
CircPROSC promotes craniosynostosis by sponging miR‐6815‐5p, thereby activating WNT3A/β‐catenin signaling and enhancing RUNX2‐mediated osteogenesis. Targeted silencing of circPROSC with MSC membrane–coated siRNA nanoparticles (MM@Lipo/si‐circPROSC) delivered postnatally into cranial sutures attenuates premature suture closure in Twist1+/– mice ...
