The Osteoblastic Microenvironment Determines the Fate of Breast Cancer Cells Disseminated in the Bone Marrow

Advanced Science, EarlyView.
This study revealed how the osteoblastic microenvironment determines the fate of cancer cells disseminated in bone, with a focus on whether they colonize, reside in quiescence, or reactivate from dormancy. Targeting integrin signaling may offer promising strategies for preventing quiescent cancer cells reactivation and bone colonization.

Promoting implant osseointegration via the osteoblast-selective β-amino acid polymer strategy

Nature Communications
Osseointegration for implants, especially bioinert implants, poses significant clinical challenges. Overcoming fibrotic encapsulation and promoting osseointegration at the implant interface are critical for successful bone repair, which highly expected ...

Gαi1/3 Is a Novel Regulatory Target for RANKL Signal Transduction and Osteoporosis

Advanced Science, EarlyView.
ABSTRACT Osteoporosis, characterized by progressive bone loss and increased fracture risk, is a growing concern as the population ages. Current treatments, though advanced, remain limited, underscoring the necessity for novel therapeutic targets. Recent studies have shown that the immune system plays a key role in osteoporosis, with osteoclasts driving

Engineering Osteoimmune Responses with Functionalized Orthopedic Implants for Post‐Operative Osteosarcoma Treatment

Advanced Science, EarlyView.
Osteosarcoma is the most common primary bone tumor with limited treatment options and a terrible prognosis. This review provides a comprehensive summary of the recent development of osteoimmunomodulatory implants for post‐operative osteosarcoma treatment, of which the potential utility in evoking durable anti‐osteosarcoma immunity and accelerating bone

Induction of osteoblast apoptosis stimulates macrophage efferocytosis and paradoxical bone formation

Bone Research
Apoptosis is crucial for tissue homeostasis and organ development. In bone, apoptosis is recognized to be a main fate of osteoblasts, yet the relevance of this process remains underexplored.

Modulating Integrin and Growth Factor Signaling With Peptides: Strategies to Synergistically Enhance Bone Tissue Regeneration

Advanced Science, EarlyView.
It has been demonstrated that, in the bone extracellular matrix (ECM), integrins and growth factor receptors (GFRs) engage in synergistic signaling to guide bone healing and regeneration. This review provides a comprehensive overview of current strategies using ECM‐derived peptides to recreate the cellular microenvironment and harness synergistic ...

Atrophic Skeletal Muscle‐Derived Extracellular Vesicles Transfer miR‐125a‐5p to Inhibit Bone Formation in Osteoporosis during Aging

Advanced Science, EarlyView.
A muscle‐bone endocrine pathway in aging is revealed in which extracellular vesicles released from atrophic skeletal muscle (Aged‐SKM‐EVs) inhibit bone formation. These EVs deliver miR‐125a‐5p to osteoblasts, thereby suppressing the SIRT7‐Sp7 signaling axis and osteogenic differentiation.

HSP90AB1‐Mediated Ubiquitin‐Proteasome Degradation of ITGBL1 Promotes Osteosarcoma Progression by Inhibiting Endoplasmic Reticulum Stress‐Induced Autophagy

Advanced Science, EarlyView.
This study delineates a novel HSP90AB1‐ITGBL1 signaling axis governing osteosarcoma. HSP90AB1 promotes K63‐linked ubiquitination and proteasomal degradation of ITGBL1. Restoring ITGBL1 induces reactive oxygen species‐dependent endoplasmic reticulum stress and pro‐death autophagy, suppressing tumor growth and metastasis.

miR‐185‐5p Derived From hUC‐MSC Exosomes via Suspension Culture Under Hypoxic Conditions Promotes Scarless Wound Healing in Mice by Precisely Regulating Collagen I/III Regeneration

Advanced Science, EarlyView.
miR‐185‐5p derived from UC‐MSC exosomes via hypoxic suspension culture promotes scarless wound healing in mice by precisely regulating collagen I/III regeneration. Exosomes derived from UC‐MSCs under a three‐dimensional bioreactor and hypoxic conditions were injected into the skin wounds of mice.
