Abstract Cellular senescence is a significant contributor to intervertebral disc aging and degeneration. However, the application of senotherapies, such as senomorphics targeting markers senescence‐associated secretory phenotype (SASP), remains limited due challenges in precise delivery. Given that natural killer group 2D (NKG2D) ligands are increased on surface senescent nucleus pulposus (NP) cells, NKG2D‐overexpressing NP cell membranes (NNPm) constructed, which expected achieve dual effect toward cells based homologous membrane fusion NKG2D‐mediated immunosurveillance mechanism. Then, mesoporous silica nanoparticles carrying peroxisome proliferator‐activated receptor‐ɣ coactivator 1α (PGC1α)inducer (SP) coated with NNPm (SP@NNPm) it found SP@NNPm selectively targets SP cores exhibit pH‐responsive drug release. Moreover, effectively induces PGC1α‐mediated mitochondrial biogenesis mitigates induced by oxidative stress SASP, thereby alleviating puncture‐induced This dual‐targeting nanotherapeutic system represents novel approach delivery for degeneration treatment.

The extracellular matrix (ECM) stores signaling molecules and facilitates mechanical biochemical in cells. However, the influence of biomimetic "rejuvenation" ECM structures on aging- degeneration-related cellular activities tissue repair is not well understood. We combined physical extrusion precise "on–off" alternating cross-linking methods to create anisotropic biomaterial microgels (MicroRod MicroSphere) explored how they regulate cell nucleus pulposus (NP) their potential antidegenerative effects intervertebral discs. NP cells exhibited aligned growth along surface MicroRod, enhanced proliferation, reduced apoptosis. This suggests an adaptive response involving adhesion mechanosensing, which causes cytoskeletal extension via environmental cues. maintain nuclear membrane integrity through YAP/TAZ pathway, activates cGAS-STING pathway rectify aging mechanisms. In vivo, MicroRod carries reduces inflammatory factor protease secretion degenerated discs, inhibiting degeneration promoting regeneration. Our findings highlight role stress maintaining activity antiaging harsh environments, providing a foundation for further research development biomaterials.
