Preventative ibandronate treatment has the most beneficial effect on the microstructure of bone in experimental tumor osteolysis [PDF]

, 2018
We investigated the effect of ibandronate on three-dimensional (3-D) microstructure and bone mass in experimentally induced tumor osteolysis. Walker carcinosarcoma cells were implanted into the left femur of female rats that received 26-day ibandronate ...

Multifunctional Bioactive Scaffold Facilitating BMSCs‐Driven Osteogenesis and Vascularization in Critical‐Sized Bone Defect Repair

Advanced Science, EarlyView.
A dual‐network bFGF@CB‐gel integrates: i) ChSMA scaffold (mechanical support/BMSCs delivery); ii) BC carrier (sustained bFGF release via EGFL/Itga2b and COMP/PI3K/AKT for adhesion/osteogenesis); iii) bFGF/PI3K/AKT/eNOS for angiogenesis. This rational, synergistic design addresses CSD bone regeneration challenges.

Alzheimer's Disease Risk Factor APOE4 Exerts Dimorphic Effects on Female Bone

Advanced Science, EarlyView.
In aging bone, osteocytes accumulate neurodegenerative risk factor Apolipoprotein E (APOE). A humanized version of the Alzheimer's disease risk allele APOE4 altered the mouse bone transcriptome and proteome, with effects in female bone surpassing the brain, including bone fragility due to suppressed osteocytic maintenance of bone quality, identifying ...

Senomorphic Small Extracellular Vesicles Delivered by a Tissue‐Adhesive α‐Lipoic‐Acid Hydrogel Enable Immuno‐Rejuvenation for Bone‐Tendon Interface Regeneration

Advanced Science, EarlyView.
This work identifies M1 macrophage‐mediated inflammation as a key driver of BMSC senescence and bone microstructural deterioration at the enthesis. A tissue‐adhesive hydrogel delivering senomorphic small extracellular vesicles suppresses this inflammatory‐senescent cascade and enhances BMSC resilience by inhibiting the cGAS‐STING‐NF‐κB pathway.

Tumor‐Induced Splenic Remodeling: Mechanisms of Systemic Immunosuppression and Emerging Therapeutic Opportunities

Advanced Science, EarlyView.
ABSTRACT Despite the transformative impact of cancer immunotherapies such as immune checkpoint blockade, durable clinical responses remain limited. Increasing evidence indicates that antitumor immunity is governed not only by the tumor microenvironment, but also by systemic immune regulation mediated by peripheral immune organs. Among these, the spleen

Iliac trabecular bone formation predicts radial trabecular bone density changes in type 1 osteoporosis

Journal of Bone and Mineral Research, 1991
Abstract In 28 patients with idiopathic or postmenopausal type 1 (spinal crush fracture) osteoporosis, resorption indices and dynamic measurements of trabecular bone formation based on in vivo tretracycline labeling in 7.5 mm transiliac biopsies have been compared with trends in radial cortical and trabecular bone density measured with ...

Harnessing Phase Separation for the Development of High‐Performance Hydrogels

Advanced Science, EarlyView.
ABSTRACT Hydrogels are indispensable for the development of next‐generation bioelectronics, soft robotics, and biomedical devices, where their mechanical properties determine performance and reliability. Among strategies to enhance hydrogel mechanics, phase separation enables controlled heterogeneity resulting in gel networks that are reinforced by ...

Injectable Porous Microspheres Loaded With Biomimetic Preconditioned Bone Marrow Mesenchymal Stem Cell‐Derived Exosomes for Vascularized Bone Regeneration

Advanced Science, EarlyView.
Schematic illustration of injectable PDA‐modified GelMA microspheres loaded with BioPre‐Exos for vascularized bone regeneration. ABSTRACT Critical‐sized bone defects remain a highly challenging clinical problem due to insufficient intrinsic self‐healing capacity.
