Cb1 Enhanced Osteogenic Differentiation Of Bmscs By Rescue Mitochondrial Metabolism

open access: yesInternational Dental Journal
Aim or purpose: CB1 is the main effector of endogenous cannabinoid system, and our previous study verified CB1 enhanced the osteo/dentinogenic differentiation of dental mesenchymal stem cells (MSCs), which might be a target for alveolar bone regeneration.

[Cardiac osteogenic sarcoma with chondroblastic differentiation].

open access: yesAnales de medicina interna (Madrid, Spain : 1984), 1996
Cardiac tumors are a rare disease. We show here one patient with a heart osteogenic sarcoma with chondroblastic differentiation. The clinical status was initiated with a cadre of cardiac tamponade. Transesophageal echocardiography and thoracic scanner were used to diagnose the cardiac tumor. The definitive diagnosis was confirmed with biopsy.

Distinct Immunomodulatory Strategies Guide Mesenchymal Stromal/Stem Cell‐Mediated Bone Regeneration

open access: yesAdvanced Science, EarlyView.
Bone regeneration by mesenchymal stem cells is strongly influenced by immune signals. This study shows that priming stem cells with regulatory immune cells or an inflammation‐resolving lipid molecule enhances bone formation through distinct immune pathways.

A BioLiving Periosteum Evokes Centripetal Regeneration in Challenging Bone Defects

open access: yesAdvanced Science, EarlyView.
Large bone defects often suffer from insufficient central healing. This study engineers a BioLiving periosteum that mimics the native structure. It sequentially delivers remote chemical cues and contact physical cues in a signaling‐relay manner, effectively recruiting and guiding endogenous cells toward the defect center.

Bone Organoids: A Novel Tool for Modeling and Managing Skeletal Disorders in Diabetes

open access: yesAdvanced Science, EarlyView.
This review synthesizes advances in bone organoid engineering and evaluates their potential to model diabetic bone fragility. Current in vitro and animal models do not fully recapitulate diabetes‐associated skeletal phenotypes. Cell‐based and scaffold‐based bone organoids are discussed as complementary approaches to reconstruct multicellular bone ...

A Dual‐Responsive Versatile Nanohybrid Orchestrating Tumor Elimination and Tumor‐Associated Osteolysis Restoration via Sequential Release

open access: yesAdvanced Science, EarlyView.
The versatile CaO2@CuMOF@HAP nanohybrid demonstrates an outstanding MMP9/pH‐triggered release performance for sequential release of osteogenic growth peptide into deep‐seated tumor‐infiltrated bone destruction areas and dual ions into tumor cells, enabling efficient tumor‐associated osteolysis restoration and tumor elimination for more comprehensive ...

Myeloid‐Derived Grancalcin Promotes Periodontal Inflammation and Pathological Bone Remodeling in Periodontitis

open access: yesAdvanced Science, EarlyView.
Grancalcin (GCA), a myeloid‐derived protein, is enriched in gingival tissues of periodontitis patients and mouse models. Through interactions with CD44 and activation of MYH9, GCA promotes NF‐κB signaling and exacerbates periodontal inflammation and bone loss.

Identification of a Force‐Induced Sox9+Acan+ Transitional Subpopulation Linked to FGF2–FGFR2–ERK Signaling in Orthodontic Bone Remodeling

open access: yesAdvanced Science, EarlyView.
Mechanical loading induces a previously unrecognized Sox9+Acan+ transitional mesenchymal cell population in the periodontal ligament that promotes osteoclastogenesis via the FGF2–FGFR2–ERK axis. Targeting this mechanoresponsive stromal population using a localized GelMA@siRNA delivery strategy attenuates pathological osteoclast overactivation and root ...

Y‐Box‐Binding Protein 1 Facilitates the Proliferation and Osteogenic Differentiation of Periodontal Ligament Stem Cells Through the Transcriptional Activation of FGF2‐Mediated Akt/GSK3β/β‐Catenin Signaling

open access: yesKaohsiung Journal of Medical Sciences
Periodontal ligament stem cells (PDLSCs) are derived from periodontal tissue and can differentiate into osteoblasts, which are ideal materials for alveolar bone repair and periodontal tissue regeneration. In this study, we aimed to explore the effects of

A Photothermal Transducer Regulates Transmembrane Calcium Flow for Synergistic Osteoarthritis Therapy

open access: yesAdvanced Science, EarlyView.
Upon NIR irradiation at 808 nm, the activity of TRPV4 was inhibited by M2M@BPSC, which led to reduced calcium influx, mitochondrial protection, and, importantly, the transcriptional activation of the STAT6‐EGR2 pathway. The improved macrophage function indirectly readjusts the equilibrium between C‐ECM and F‐ECM to reconstruct a suitable ...
