研究问题
The central challenge lies in the disrupted communication between senescent NP cells and local immune cells within this confined, immune-privileged niche.；Therefore, how to breach the disc’s physical and biological barriers and precisely rewire beneficial intercellular communication remains a key scientific challenge for addressing IVDD.；To address this challenge, we propose a spatially precise therapeutic paradigm based on a Chinese microneedle system.
方法
Cell Cycle and Apoptosis Kit, Calcein/PI Cell Viability/Cytotoxicity Assay kit, Senescence β-Galactosidase Staining kit, Reactive Oxygen Species kit, and 2′,7′-dichlorodihydrofluorescein diacetate (DCFH-DA) probe and JC-1 mitochondrial membrane potential detection kit were provided by Beyotime Biotechnology (Shanghai, China).；Live and Dead Cell Staining kit was obtained from Abbkine Scientific Co.；The morphology of liposomes was characterized by negative staining.；Subsequently, 10 μl of 2% (w/v) uranyl acetate (TED PELLA, catalog no. 19481) was applied to the grid for negative staining for 1 min, and the excess stain was removed with filter paper.
核心结论
Under ultrasound stimulation, films of varying thicknesses (16, 32, and 64 μm) generated stable voltage outputs, which increased with ultrasound power (0.1, 0.5, and 1 W) (Fig.；As the culture duration increased to 72 and 120 h, cell numbers continued to increase, and no obvious accumulation of red dead-cell signals was observed (Fig.；In contrast, ES substantially reprogrammed the transcriptional landscape: RNA-seq identified 224 genes significantly up-regulated in the ES group, whereas 411 genes were up-regulated in the Aging group (Fig. ‖ 结论：Collectively, this work proposes an “electro-immunometabolic axis” as a new therapeutic paradigm for disc regeneration, providing a platform for deep-tissue repair and next-generation regenerative therapies.
局限
These risks were not captured within the present study and warrant systematic long-term evaluation.；Future work will focus on monitoring PLLA degradation kinetics and exploring copolymer or surface-modified designs to mitigate potential adverse effects.；Future studies employing microelectrode array mapping or fluorescence-labeled glycine tracking will be required to quantitatively define the spatial extent and gradient of the dual-field within the disc microenvironment.
