Recent advances in the combined delivery platform that integrate nano-/microscale carriers and with 3D hydrogel network for bone regeneration are *** strategies for bioactive molecules delivery involving nanoparticles, nanosheets, and microspheres, along with extra stimuli such as near-infrared light, temperature changes, ultrasonication, and inflammatory conditions, are *** prospects and challenges for the clinical translation and the development of nano-/microscale incorporated hydrogel-based delivery platform are discussed. Bioactive molecules have shown great promise for effectively regulating various bone formation processes, rendering them attractive therapeutics for bone regeneration. However, the widespread application of bioactive molecules is limited by their low accumulation and short half-lives in vivo. Hydrogels have emerged as ideal carriers to address these challenges, offering the potential to prolong retention times at lesion sites, extend half-lives in vivo and mitigate side effects, avoid burst release, and promote adsorption under physiological conditions. This review systematically summarizes the recent advances in the development of bioactive molecule-loaded hydrogels for bone regeneration, encompassing applications in cranial defect repair, femoral defect repair, periodontal bone regeneration, and bone regeneration with underlying diseases. Additionally, this review discusses the current strategies aimed at improving the release profiles of bioactive molecules through stimuli-responsive delivery, carrier-assisted delivery, and sequential delivery. Finally, this review elucidates the existing challenges and future directions of hydrogel encapsulated bioactive molecules in the field of bone regeneration.

Characteristic changes in astrocyte properties during astrocyte-to-neuron conversion induced by NeuroD1/Ascl1/Dlx2

引用

Neural Regeneration Research 2025年第6期20卷 1801-1815页

作者： Qing he Zhen Wang Yuchen Wang Mengjie Zhu Zhile Liang Kanghong Zhang Yuge Xu Gong Chen GHM Institute of CNS Regeneration Jinan UniversityGuangzhouGuangdong ProvinceChina

Direct in vivo conversion of astrocytes into functional new neurons induced by neural transcription factors has been recognized as a potential new therapeutic intervention for neural injury and degenerative disorders. However, a few recent studies have claimed that neural transcription factors cannot convert astrocytes into neurons, attributing the converted neurons to pre-existing neurons mis-expressing transgenes. In this study, we overexpressed three distinct neural transcription factors––NeuroD1, Ascl1, and Dlx2––in reactive astrocytes in mouse cortices subjected to stab injury, resulting in a series of significant changes in astrocyte properties. Initially, the three neural transcription factors were exclusively expressed in the nuclei of astrocytes. Over time, however, these astrocytes gradually adopted neuronal morphology, and the neural transcription factors was gradually observed in the nuclei of neuron-like cells instead of astrocytes. Furthermore,we noted that transcription factor-infected astrocytes showed a progressive decrease in the expression of astrocytic markers AQP4(astrocyte endfeet signal), CX43(gap junction signal), and S100β. Importantly, none of these changes could be attributed to transgene leakage into preexisting neurons. Therefore, our findings suggest that neural transcription factors such as NeuroD1, Ascl1, and Dlx2 can effectively convert reactive astrocytes into neurons in the adult mammalian brain.

共同富裕是中国特色社会主义的本质要求,是人民群众的共同期盼。共同富裕旨在实现生活品质全面提升,不仅追求物质层面的富饶与充裕,而且强调精神世界的丰富与满足,即物质富足与精神充实和谐并进。随着中国特色社会主义迈向新发展阶段,积极培育并激发农民精神生活共同富裕,有助于提升农民文化底蕴与道德修养,为乡村文化振兴提供强大精神动力和智力支持,从而推动乡村社会全面发展与繁荣。乡村文化振兴是解决城乡人民精神文化生活发展不平衡问题的重要手段,是促进农民精神生活共同富裕的关键途径。乡村文化振兴具有统一思想认识、培育乡风文明、实现精神自强等显著优势,为农民精神生活共同富裕提供思想基础、文化资源和内生动力。然而,囿于农民综合素养不高、乡村文化价值在多元文化碰撞中日渐式微以及文化振兴载体建设不畅等现实障碍,农民精神生活共同富裕的任务任重而道远。为此,应通过强化宣传教育、推动乡村文化融入社会主义文化繁荣大局之中、建设乡村新时代文明实践中心等举措,充分发挥乡村文化振兴在促进农民精神生活共同富裕中的重要作用。
