In aging society, osteoporotic fractures have become one major social problem threatening the health of elderly population in China. Compared with conventional fractures, low bone mass, defect and retarded healing issues lead to great difficulties treatment rehabilitation. Addressing concerns clinical settings, we proposed “three one” repair strategy focusing on anti-osteoporosis therapies, appropriate grafting fracture accelerating. We summarize misconceptions strategies for management, expecting improvement prognosis outcomes further improve therapeutic effect living quality patients.

Neural-vascular networks are densely distributed through periosteum, cortical bone, and cancellous which is of great significance for bone regeneration remodeling. Although significant progress has been made in tissue engineering, ineffective regeneration, delayed osteointegration still remains an issue due to the ignorance intrabony nerves blood vessels. Herein, inspired by space-filling polyhedra with open architectures, polyhedron-like scaffolds spatial topologies prepared via 3D-printing technology mimic meshwork structure bone. Benefiting from its topologies, greatly promoted osteogenic differentiation mesenchymal stem cells (BMSCs) activating PI3K-Akt signals, exhibiting satisfactory performance on angiogenesis neurogenesis. Computational fluid dynamic (CFD) simulation elucidates that have a relatively lower area-weighted average static pressure, beneficial osteogenesis. Furthermore, vivo experiments further demonstrate obviously promote formation osteointegration, as well inducing vascularization ingrowth nerves, leading innervated vascularized regeneration. Taken together, this work offers promising approach fabricating multifunctional without additional exogenous seeding growth factors, holds potential functional clinical translation.

Abstract Bone formation and deposition are initiated by sensory nerve infiltration in adaptive bone remodeling. Here, we focused on the role of Semaphorin 3A (Sema3A), expressed nerves, mechanical loads-induced withdrawal using orthodontic tooth movement (OTM) model. Firstly, was activated after 3rd day OTM, coinciding with a decrease nerves an increase pain threshold. Sema3A, rather than growth factor (NGF), highly both trigeminal ganglion axons periodontal ligament following OTM. Moreover, vitro loads upregulated Sema3A neurons instead human cells (hPDLCs) within 24 hours. Furthermore, exogenous restored suppressed alveolar osteogenic differentiation hPDLCs induced overload. Mechanistically, prevented overstretching F-actin overload through ROCK2 pathway, maintaining mitochondrial dynamics as fusion. Therefore, exhibits dual therapeutic effects formation, pain-sensitive analgesic positive regulator for formation.

The complexity of repairing large segment defects and eradicating residual tumor cell puts the osteosarcoma clinical management challenging. Current biomaterial design often overlooks crucial role precisely regulating innervation in bone regeneration. Here, we develop a Germanium Selenium (GeSe) co-doped polylactic acid (PLA) nanofiber membrane-coated tricalcium phosphate bioceramic scaffold (TCP-PLA/GeSe) that mimics bone-periosteum structure. This biomimetic offers dual functionality, combining piezoelectric photothermal conversion capabilities while remaining biodegradable. When subjected to ultrasound irradiation, US-electric stimulation TCP-PLA/GeSe enables spatiotemporal control neurogenic differentiation. feature supports early during formation, promoting differentiation Schwann cells (SCs) by increasing intracellular Ca

Abstract Chronic pain continues to be a significant global burden despite the availability of variety nonpharmacologic and pharmacologic treatment options. Thus, there is need for new analgesics with novel mechanisms action. In this regard, antibodies directed against nerve growth factor (NGF-Abs) are class agents in development chronic conditions such as osteoarthritis low-back pain. This comprehensive narrative review summarizes evidence supporting pronociceptive functions NGF that include contributing peripheral central sensitization through tropomyosin receptor kinase A activation stimulation local neuronal sprouting.

Abstract Denervation of skeletal muscles induces severe muscle atrophy, which is preceded by cellular alterations such as increased plasma membrane permeability, reduced resting potential and accelerated protein catabolism. The factors that induce these changes remain unknown. Conversely, functional recovery following denervation depends on successful reinnervation. Here, we show activation nicotinic acetylcholine receptors (nAChRs) quantal release (ACh) from motoneurons sufficient to prevent induced denervation. Using in vitro assays, ACh non-hydrolysable analogs repressed the expression connexin43 connexin45 hemichannels, promote atrophy. In co-culture studies, connexin43/45 hemichannel knockout or knockdown innervation fibers dorsal root ganglion neurons. Our results released exerts a hitherto unknown function independent myofiber contraction. nAChRs connexin hemichannels are molecular targets for therapeutic intervention variety pathological conditions with synaptic neuromuscular transmission.

Abstract Pain is a central feature of soft tissue trauma, which under certain contexts, results in aberrant osteochondral differentiation tissue-specific stem cells. Here, the role sensory nerve fibers this abnormal cell fate decision investigated using severe extremity injury model mice. Soft trauma NGF (Nerve growth factor) expression, particularly within perivascular types. Consequently, NGF-responsive axonal invasion occurs precedes osteocartilaginous differentiation. Surgical denervation impedes ingrowth, with significant delays cartilage and bone formation. Likewise, either deletion Ngf or two complementary methods to inhibit its receptor TrkA (Tropomyosin kinase A) lead similar Mechanistically, single-cell sequencing suggests shift from TGFβ FGF signaling activation among pre-chondrogenic cells after denervation. Finally, analysis human pathologic specimens databases confirms relevance NGF-TrkA disease. In sum, NGF-mediated TrkA-expressing ingrowth drives trauma. inhibition may have dual therapeutic use both as an analgesic negative regulator
