细菌巧造人工耳!马竞/张天宇团队突破耳廓畸形修复难题,利用细菌编织人工耳廓支架
生物世界· 2025-05-27 03:57
Core Viewpoint - The article discusses a breakthrough in reconstructive surgery for ear deformities, utilizing bacteria as a "biological 3D printer" to create customizable artificial ear scaffolds, potentially transforming clinical practices in auricular reconstruction [2][4]. Group 1: Challenges in Traditional Methods - Traditional ear reconstruction methods involve harvesting rib cartilage, which presents three main challenges: insufficient rib cartilage in children requiring multiple surgeries, the complexity of sculpting and stitching that relies heavily on the surgeon's skill, and the risk of postoperative complications such as infections and scaffold exposure [4][5]. - Existing artificial materials used as cartilage substitutes also face issues, including manual shaping and stitching, along with the risk of rejection [4]. Group 2: Innovative Approach - The research team focused on the bacterium Komagataeibacter xylinus, which can synthesize bacterial cellulose known for its high purity, nanoscale network structure, excellent biocompatibility, and functionalization properties [4][5]. - The bacteria exhibit an "oxygen navigation" feature, allowing them to gather in oxygen-rich areas and secrete nanofibers, which are utilized to create the ear scaffold [5]. Group 3: Key Innovations in Scaffold Production - The team designed a high-oxygen-permeable silicone mold to achieve three critical controls: precise molds created from 3D-printed ear models, dynamic oxygen supply to guide bacteria evenly throughout the scaffold, and nanometer-level precision in the cellulose fibers produced [5][7]. - The cellulose fibers have a diameter of 20-100 nanometers and form a cartilage-like network structure with mechanical strength comparable to real ear cartilage, with an elastic modulus ranging from 3.89 to 9.56 MPa [5][8]. Group 4: Performance and Clinical Implications - After 21 days of bacterial "biomanufacturing" and purification, the artificial ear scaffolds demonstrated remarkable characteristics: precise replication of ear structures, high tensile strength with no deformation after 50 days of immersion, long-term stability in the body, and extremely low endotoxin levels [8][9]. - The scaffolds show over 95% survival rates for cartilage and skin cells, allowing for rapid integration with surrounding tissues, indicating significant clinical application potential for personalized ear reconstruction [9]. Group 5: Broader Impact - This research marks the first application of microbial manufacturing technology in organ reconstruction, offering hope for patients with ear deformities and paving the way for future developments in complex tissue engineering, potentially extending to heart valves and vascular networks [9].
KROGER PARTNERING WITH THE LEUKEMIA & LYMPHOMA SOCIETY (LLS) TO HELP KIDS WITH BLOOD CANCER

对抗衰老,生活方式比DNA更有话语权 | Healthcare View

有很多习惯,我们知道它对健康不利,但总会"不自觉"地放纵自己,比如熬夜、吃高热量的垃圾食品等等—— 但其实,这些坏习惯对我们健康的危害比想象中更严重。 首先,《Nature》子刊的一篇研究论文表明,一系列环境因素,包括生活方式 (例如吸烟、运动锻炼) 和生活条 件,对健康和衰老的影响比遗传因素的影响更大。 其次,睡眠作为人体最基本的生理需求之一,其质量的高低直接关系到免疫系统的功能和整体健康状态。一项 发表在《The Journal of Immunology》的研究指出,即使是短暂的一夜不睡,也会对免疫系统产生显著的负面影 响,使单核细胞的特征发生改变,进而引发慢性炎症和相关疾病的风险增加。 最后,饮食习惯对健康的影响也不容小觑。另一项发表在《Nature》子刊的研究显示,即使是短期的高热量饮 食,也会对大脑结构和功能产生长期的不良影响。 这些研究为我们提供了关于生活习惯对健康影响的有力证据,同时,它们不仅为我们敲响了警钟,也为改善健 康提供了新的方向。 生活方式的影响,远超基因 虽然人类的人均寿命已经突破了80岁,但是我们关于衰老的认知仍然在被不断颠覆——2025年2月19日,牛 津大学的研究人员在国际顶 ...
