Abstract Bone tissue relies on the intricate interplay between blood vessels and nerve fibers, both are essential for many physiological pathological processes of skeletal system. Blood provide necessary oxygen nutrients to bone tissues, remove metabolic waste. Concomitantly, fibers precede during growth, promote vascularization, influence cells by secreting neurotransmitters stimulate osteogenesis. Despite critical roles components, current biomaterials generally focus enhancing intraosseous vessel repair, while often neglecting contribution nerves. Understanding distribution main functions in is crucial developing effective engineering. This review first explores anatomy highlighting their vital embryonic development, metabolism, repair. It covers innovative regeneration strategies directed at accelerating intrabony neurovascular system over past 10 years. The issues covered included material properties (stiffness, surface topography, pore structures, conductivity, piezoelectricity) acellular biological factors [neurotrophins, peptides, ribonucleic acids (RNAs), inorganic ions, exosomes]. Major challenges encountered neurovascularized materials clinical translation have also been highlighted. Furthermore, discusses future research directions potential developments aimed producing repair that more accurately mimic natural healing tissue. will serve as a valuable reference researchers clinicians novel into practice. By bridging gap experimental practical application, these advancements transform treatment defects significantly improve quality life patients with bone-related conditions.

We used Mendelian randomization (MR) approach to examine whether genetically determined inflammation-related risk factors play a role in the onset of osteoporosis (OP) European population. Genome-wide association studies (GWASs) summary statistics estimated bone mineral density (eBMD) obtained from public database GEnetic Factors for OSteoporosis Consortium (GEFOS) including 142,487 people. For exposures, we utilized GWAS data 9 diseases chronic kidney disease (CKD) (41,395 cases and 439,303 controls), type 2 diabetes (T2D) (88,427 566,778 Alzheimer's (AD) (71,880 cases, 383,378 controls) major depression disorder (MDD) (9240 9519 lifestyle behaviors are different consortiums.
