Coaxial three-dimensional (3D) printing enables precise, multi-material deposition, demonstrating strong potential across diverse fields, including industrial monitoring, health sensing, artificial intelligence (AI) hardware, and food packaging. Its core value is prominently realized in the biomedical domain, where it has revolutionized tissue engineering. The present review consolidates advancements in 3D coaxial bioprinting across diverse biomedical applications, focusing on its transformative potential in vascularized tissue engineering, spatiotemporal drug delivery, and patient-specific disease modeling. This review also explored unresolved challenges, such as bioink optimization and functional vascularization, while proposing integrative solutions that combine coaxial printing with AI and hybrid fabrication strategies. The versatility of coaxial 3D printing is evident in its numerous biomedical applications, such as cardiovascular tissue engineering, skin regeneration, bone repair, and functional muscle constructs. In bone tissue engineering, coaxial printing facilitates vascularization and osteochondral regeneration through spatially controlled bioink and scaffold design. Applications extend to cartilage repair, neuromuscular junction modeling, and tumor microenvironment replication. Despite progress, challenges persist in optimizing bioink rheology, achieving functional vascularization, and scaling production for clinical application. Notably, the integration of advanced materials, such as hydrogels and inorganic salts, with hybrid strategies, including electrospinning and sacrificial printing, highlights the synergistic potential of coaxial bioprinting to transform regenerative medicine, drug screening, and personalized therapies. Ongoing innovations in multi-scale, multi-cellular printing can bridge the gap between engineered constructs and biological functional tissues.
同轴三维(3D)打印可实现精确的多材料沉积,在工业监控、健康传感、人工智能(AI)硬件和食品包装等多个领域显示出强大的潜力。它的核心价值在生物医学领域得到了突出的体现,它彻底改变了组织工程。本综述整合了3D同轴生物打印在不同生物医学应用中的进展,重点关注其在血管化组织工程、时空药物输送和患者特异性疾病建模方面的变革潜力。本文还探讨了尚未解决的挑战,如生物链接优化和功能性血管化,同时提出了将同轴打印与人工智能和混合制造策略相结合的综合解决方案。同轴3D打印的多功能性在其众多生物医学应用中是显而易见的,例如心血管组织工程,皮肤再生,骨骼修复和功能性肌肉结构。在骨组织工程中,同轴打印通过空间控制的生物链接和支架设计促进血管化和骨软骨再生。应用扩展到软骨修复,神经肌肉连接建模和肿瘤微环境复制。尽管取得了进展,但在优化生物链流变学、实现功能性血管化和规模化生产临床应用方面仍然存在挑战。值得注意的是,将水凝胶和无机盐等先进材料与包括静电纺丝和牺牲打印在内的混合策略相结合,突出了同轴生物打印在改变再生医学、药物筛选和个性化治疗方面的协同潜力。不断创新的多尺度、多细胞打印技术可以弥合工程结构和生物功能组织之间的差距。

The clinical efficacy of Irinotecan is constrained by individual variability in its enzymatic conversion to the active metabolite, SN38. While direct administration of SN38 bypasses this enzymatic process and demonstrates potent anti-tumor activity, its clinical application remains hindered by poor physicochemical properties and off-target toxicity. These challenges highlight the necessity for efficient drug delivery strategies. Prodrug nanoassemblies combine the advantages of nano drug delivery technology and prodrug strategy, offering an effective approach to address these limitations. The modification module in prodrug design plays a critical role in imparting prodrugs self-assembly ability. Monomethyl branched-chain fatty acids (mmBCFAs), known for their biocompatibility and metabolite safety, show great potential as a worthy option. In this study, we designed and synthesized SN38-SS-BAc18 by incorporating 16-methylheptanoic acid (BAc18) as the modification module, and a disulfide bond as the responsive module for tumor-specific activation. The resulting SN38-SS-BAc18 significantly improved the undesirable physicochemical properties of SN38 and exhibited enhanced self-assembly performance. Due to its prolonged circulation time, high tumor accumulation, and specific release profiles, the prodrug nanoassemblies (SN38-SS-BAc18 NPs) exhibited superior anti-tumor efficacy and biosafety. This study addressed multiple therapeutic limitations of SN38 and Irinotecan, providing valuable insights for the rational design of efficient prodrug nanoassemblies for colorectal cancer treatment.
伊立替康的临床疗效受到其酶转化为活性代谢物SN38的个体差异的限制。虽然直接给药SN38可以绕过这一酶促过程并显示出强大的抗肿瘤活性,但其物理化学性质差和脱靶毒性仍阻碍了其临床应用。这些挑战突出了制定有效给药战略的必要性。前体药物纳米组件结合了纳米药物传递技术和前体药物策略的优点,为解决这些局限性提供了有效的途径。前体药物设计中的修饰模块对赋予前体药物自组装能力起着至关重要的作用。单甲支链脂肪酸(mmBCFAs)以其生物相容性和代谢安全性而闻名,显示出作为一种有价值的选择的巨大潜力。本研究以16-甲基庚酸(BAc18)为修饰模块,以二硫键为肿瘤特异性激活响应模块,设计合成了SN38-SS-BAc18。所得SN38- ss - bac18显著改善了SN38的理化性质,并表现出增强的自组装性能。SN38-SS-BAc18纳米组件具有循环时间长、肿瘤蓄积大、释放特异性强等特点,具有良好的抗肿瘤疗效和生物安全性。本研究解决了SN38和伊立替康的多重治疗局限性,为合理设计有效的结直肠癌治疗前药纳米组件提供了有价值的见解。

CD4+ T cells play a pivotal role in adaptive immunity, recognizing peptide antigens presented by MHC II molecules during infections and tumor development. Identifying immunodominant MHC II epitopess is essential for understanding CD4+ T cell responses; however, current methods such as mass spectrometry, suffer from low sensitivity and throughput, while computational algorithms show variable accuracy. To overcome these challenges, we developed EliteMHCII, a high-throughput immunopeptidome profiling platform that identifies antigen-derived MHC II epitopes and measures peptide binding affinity across 24 globally common MHC II alleles. Using EliteMHCII, we assessed the immunodominant epitopes of the SARS-CoV-2 RBD protein. Validation in vaccinated individuals and humanized mouse models revealed a strong correlation between high-affinity peptides and robust CD4+ T cell responses, while low-affinity peptides failed to elicit responses. Therefore, our immunopeptidome profiling platform, EliteMHCII, serves as a rapid, high throughput, feasible platform for CD4+ T cell epitope discovery at a global populational level in the context of infectious diseases and cancer immunotherapy.
CD4+ T细胞在适应性免疫中发挥关键作用,在感染和肿瘤发展过程中识别MHC II分子呈递的肽抗原。识别免疫显性MHC II表位对于理解CD4+ T细胞反应至关重要;然而,目前的方法,如质谱法,受到低灵敏度和吞吐量的影响,而计算算法显示出可变的准确性。为了克服这些挑战,我们开发了EliteMHCII,这是一个高通量免疫肽球分析平台,可以识别抗原来源的MHCII表位,并测量24个全球常见的MHCII等位基因的肽结合亲和力。使用EliteMHCII,我们评估了SARS-CoV-2 RBD蛋白的免疫优势表位。在接种疫苗个体和人源化小鼠模型中的验证表明,高亲和力肽与稳健的CD4+ T细胞应答之间存在很强的相关性,而低亲和力肽无法引起应答。因此,我们的免疫肽分析平台EliteMHCII可作为一个快速、高通量、可行的平台,在传染病和癌症免疫治疗的背景下,在全球人群水平上发现CD4+ T细胞表位。

The emergence of cultivated meat has attracted much attention as a revolutionary product for meat. Biomaterial scaffolds are the key component and have been extensively studied in cultivated meat production, enabling cell adhesion, proliferation, and directed differentiation. However, the structural and mechanical biomimicry of edible scaffolds is hard to be achieved, hindering the large-scale production of cultivated meats. In this paper, we comprehensively summarize the construction of cultivated meat from cell-laden biomimetic scaffolds and its future research directions. We describe the cellular components of cultivated meat composition and their culture medium components. To tailor more edible scaffolds for high-efficient production of cultivated meats, advanced techniques including 3D bioprinting, electrostatic spinning, and tissue molding techniques have been developed. We then discuss recent research advances in scaffolding materials that maintain the three-dimensional (3D) morphology of cultivated meats and bioreactors. Next, we discussed the conditions and problems that should be solved for the industrial production of cultivated meat. Finally, we outline current challenges in the development of cultivated meat and a prospective outlook for the future of cultivated meat. We anticipate that the continued development of cultivated meat will lead to significant advances in the food and medical fields.

Background

Osteoarthritis (OA) is a degenerative joint disorder influenced by genetic, molecular, and environmental factors. Programmed cell death (PCD) pathways, including apoptosis, pyroptosis, necroptosis, ferroptosis, and autophagy, are linked to cartilage degradation, but their role in OA pathogenesis remains unclear.

Methods

Based on a large-scale GWAS database, this study employs a two-sample Mendelian randomization (MR) framework, integrating genomic data from 14 genes related to PCD at three levels (DNA methylation, gene expression, and protein abundance) to reveal causal relationships between these genes and OA. The MR analysis utilizes QTLs (mQTL, eQTL, and pQTL) as instrumental variables and employs five regression models (MR-Egger regression, Random-Effects Inverse Variance Weighted, Weighted Median, Weighted Mode, and Simple Mode) to assess causal effects. Furthermore, the reliability of causal inference is strengthened through FDR multiple testing correction, Steiger test, and colocalization analysis. Multi-omics evidence is integrated to identify key PCD genes causally related to OA. Finally, enrichment analysis, PPI analysis, and OA-related transcriptome analysis are used to explore the biological mechanisms of these key PCD genes.

Findings

Through MR analysis, we ultimately identified 103 PCD-related CpG sites, 170 PCD-related gene expressions, and 53 PCD-related protein levels that have significant causal relationships with OA. Multi-omics integration pinpointed 2 Tier 1 genes (CASP10, CASP3) and 14 Tier 2 genes (e.g., FGR, GAPDH). Validation across three cohorts confirmed causal associations for CASP10, GAPDH, PARK7, and others. Enrichment analysis implicated these genes in critical biological processes, such as neuronal apoptosis, protease binding, and the MAPK signaling pathway. Protein-protein interaction (PPI) network analysis identified CASP3 (Degree ​= ​9) and CASP10 (Degree ​= ​4) as central hubs, suggesting they may play a central role in the pathophysiological mechanisms of OA and could serve as potential therapeutic targets for OA. Transcriptome analysis confirmed MR findings. Tier 1 gene CASP3 was significantly upregulated in OA patients (log2FC ​= ​1.30, adjusted P ​< ​0.05), and CASP10 showed non-significant upregulation. Tier 2 genes (GAPDH, CD14, CHMP2B, GM2A, ITGAM) also showed significant changes (P ​< ​0.05) consistent with MR results.

Interpretation

This study provides a multi-omic framework for understanding the role of PCD in OA, providing insights into potential PCD-targeted therapies.
骨关节炎(OA)是一种受遗传、分子和环境因素影响的退行性关节疾病。程序性细胞死亡(PCD)途径,包括细胞凋亡、焦亡、坏死亡、铁亡和自噬,都与软骨降解有关,但它们在OA发病机制中的作用尚不清楚。方法本研究基于大规模GWAS数据库,采用双样本孟德尔随机化(MR)框架,整合来自14个PCD相关基因的基因组数据,从三个水平(DNA甲基化、基因表达和蛋白质丰度)揭示这些基因与OA之间的因果关系。MR分析利用qtl (mQTL、eQTL和pQTL)作为工具变量,并采用5种回归模型(MR- egger回归、随机效应反方差加权、加权中位数、加权模式和简单模式)来评估因果关系。通过FDR多元检验校正、Steiger检验和共定位分析,增强了因果推理的信度。整合多组学证据以确定与OA相关的关键PCD基因。最后,通过富集分析、PPI分析和oa相关转录组分析,探讨这些关键PCD基因的生物学机制。通过MR分析,我们最终确定了103个与pcd相关的CpG位点,170个与pcd相关的基因表达,53个与pcd相关的蛋白水平与OA有显著的因果关系。多组学整合确定了2个一级基因(CASP10、CASP3)和14个二级基因(如FGR、GAPDH)。三个队列的验证证实了CASP10、GAPDH、PARK7和其他基因的因果关系。富集分析表明这些基因参与关键的生物学过程,如神经元凋亡、蛋白酶结合和MAPK信号通路。蛋白-蛋白相互作用(PPI)网络分析发现CASP3(度= 9)和CASP10(度= 4)是中心枢纽,提示它们可能在OA的病理生理机制中发挥核心作用,并可能作为OA的潜在治疗靶点。转录组分析证实了MR的发现。OA患者中一级基因CASP3显著上调(log2FC = 1.30,校正P <; 0.05), CASP10无显著上调。Tier 2基因(GAPDH、CD14、CHMP2B、GM2A、ITGAM)也有显著变化(P < 0.05),与MR结果一致。本研究为理解PCD在OA中的作用提供了一个多组学框架,为潜在的PCD靶向治疗提供了见解。

Direct ink writing (DIW) is a room-temperature extrusion-based 3D printing technique that enables the fabrication of dense, customizable implants from viscous inks with precise spatial control. In this study, we present an engineering design framework for DIW-printed PCL/Laponite composites by tuning ink formulations and printing orientations to systematically investigate and control the complex interplay between shape fidelity, mechanical performance, and cellular response. Our findings show that printing at 0° orientation enhances filament-aligned surface topographies, which guide osteoblast attachment and significantly promote cell proliferation and mineralization. In contrast to previous studies using fused deposition modeling (FDM), we observe that printing at 90° orientation (perpendicular to the tensile load direction) results in higher mechanical performance due to improved filament bonding. Increasing Laponite loading (up to 30 ​%) improves shape retention by increasing ink viscosity, raises Young's modulus by up to 110 ​%, and enhances surface bioactivity by introducing hydrophilic and bioactive cues. This study provides a tunable strategy for engineering bioactive and surface-active implants for the clinical need for non-load-bearing orthopaedic applications where structural integrity, surface-mediated osteointegration, and customized geometry are clinically essential.
直接墨水书写(DIW)是一种基于室温挤压的3D打印技术,可以通过精确的空间控制,用粘性墨水制造致密的、可定制的植入物。在这项研究中,我们提出了一个diw打印PCL/Laponite复合材料的工程设计框架,通过调整油墨配方和打印方向,系统地研究和控制形状保真度,机械性能和细胞响应之间的复杂相互作用。我们的研究结果表明,0°取向的打印增强了细丝排列的表面形貌,从而引导成骨细胞附着,显著促进细胞增殖和矿化。与之前使用熔融沉积建模(FDM)的研究相反,我们观察到在90°方向(垂直于拉伸负载方向)上打印由于改善了长丝粘合而具有更高的机械性能。增加拉脱石负载(高达30%)通过增加油墨粘度来改善形状保持,将杨氏模量提高高达110%,并通过引入亲水性和生物活性提示来增强表面生物活性。该研究为非承重骨科应用的工程生物活性和表面活性植入物的临床需求提供了可调策略,其中结构完整性、表面介导的骨整合和定制的几何形状是临床必需的。

Cervical cancer is one of the leading causes of cancer-related deaths among women worldwide, imposing a particularly heavy burden in low- and middle-income countries. In recent years, advanced artificial intelligence (AI)-based technologies, including convolutional neural networks (CNNs) for image analysis and natural language processing (NLP) of electronic health records (EHRs), have substantially improved detection performance, individualized risk prediction, and the design of tailored treatment regimens. By leveraging expert visual recognition and synthesizing multimodal clinical data, these approaches offer the potential for more accurate screening and faster diagnosis. However, routine adoption hinges on resolving issues of data heterogeneity, algorithm interpretability, and ethical deployment. In this review, we summarize the latest AI breakthroughs in cervical cancer management, emphasize their promise for enhancing early intervention and personalized therapy, and call for rigorous validation to ensure safe, equitable integration into practice.
子宫颈癌是全世界妇女癌症相关死亡的主要原因之一,在低收入和中等收入国家造成特别沉重的负担。近年来,先进的基于人工智能(AI)的技术,包括用于图像分析的卷积神经网络(cnn)和电子健康记录(EHRs)的自然语言处理(NLP),大大提高了检测性能、个性化风险预测和定制治疗方案的设计。通过利用专家视觉识别和综合多模式临床数据,这些方法提供了更准确的筛查和更快诊断的潜力。然而,常规采用取决于解决数据异构性、算法可解释性和道德部署等问题。在这篇综述中,我们总结了人工智能在宫颈癌管理方面的最新突破,强调了它们在加强早期干预和个性化治疗方面的潜力,并呼吁进行严格的验证,以确保安全、公平地融入实践。

Organic room temperature phosphorescent (RTP) materials, characterized by their prolonged luminescence lifetime and superior biocompatibility, exhibit significant potential for applications in bioimaging. Through the application of time resolved techniques, the interference caused by tissue autofluorescence can be substantially minimized, enabling high signal-to-background ratio imaging. Furthermore, these materials serve as promising candidates for temperature sensing probes and photodynamic therapy agents. Although research on RTP materials has expanded rapidly in recent years, a comprehensive review covering organometallic and pure organic phosphorescent materials for bioimaging remains limited. This paper systematically summarizes recent advancements in both organometallic and pure organic phosphorescent materials used in bioimaging and critically discusses the challenges they encounter, aiming to provide valuable insights for future developments in this field.

BCR-ABL positive (BCR-ABL+) leukemia is driven by constitutive activation of tyrosine kinase activity, with tyrosine kinase inhibitors (TKIs) serving as the standard treatment. However, resistance to TKIs remains a significant clinical challenge. In this study, we demonstrate that HSPA8 is highly expressed in BCR-ABL+ ​leukemia cells, and elevated HSPA8 expression correlates with poor prognosis in BCR-ABL+ ​B-acute lymphoblastic leukemia (B-ALL). Inhibition of HSPA8 using Apoptozole (Az) or VER15508 (VER) reduced the viability of BCR-ABL+ ​leukemia cells, induced cell death, and suppressed colony formation. Through proteomic analysis, we identified GPX4, a key regulator of ferroptosis, as a major target of HSPA8 inhibition. Notably, co-treatment with HSPA8 inhibitors and GPX4 inhibitors (RSL3), or TKIs, synergistically downregulated GPX4 expression and induced ferroptosis in BCR-ABL+ ​leukemia cells, including those resistant to TKIs. In vivo, combination therapy with Az and RSL3 significantly prolonged survival in a BCR-ABL+ ​leukemia mouse model. Overall, our findings provide compelling evidence that targeting HSPA8, in combination with GPX4 inhibition or TKIs, can effectively induce ferroptosis, overcome drug resistance, and offer a novel therapeutic strategy for these malignancies.
BCR-ABL阳性(BCR-ABL+)白血病是由酪氨酸激酶活性的组成性激活驱动的,酪氨酸激酶抑制剂(TKIs)作为标准治疗。然而,对TKIs的耐药性仍然是一个重大的临床挑战。在本研究中,我们证实HSPA8在BCR-ABL+白血病细胞中高表达,并且HSPA8表达升高与BCR-ABL+ b -急性淋巴细胞白血病(B-ALL)的预后不良相关。凋亡唑(Az)或VER15508 (VER)抑制HSPA8降低BCR-ABL+白血病细胞的活力,诱导细胞死亡,抑制集落形成。通过蛋白质组学分析,我们确定了铁ptosis的关键调节因子GPX4是HSPA8抑制的主要靶点。值得注意的是,与HSPA8抑制剂和GPX4抑制剂(RSL3)或TKIs共同治疗,协同下调GPX4表达并诱导BCR-ABL+白血病细胞(包括对TKIs耐药的细胞)铁下垂。在体内,Az和RSL3联合治疗可显著延长BCR-ABL+白血病小鼠模型的生存期。总之,我们的研究结果提供了令人信服的证据,表明靶向HSPA8,结合GPX4抑制或TKIs,可以有效地诱导铁下垂,克服耐药性,并为这些恶性肿瘤提供了一种新的治疗策略。

Neurodegenerative diseases including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS) remain a major global health challenge due to their progressive nature and lack of curative treatments. Traditional animal models and 2D cell cultures fail to recapitulate the complex microenvironment and human-specific pathophysiology of these disorders. In response, advanced 3D in vitro models incorporating functional biomaterials have emerged as promising platforms for replicating disease mechanisms, enabling personalized medicine, and accelerating therapeutic discovery. This review highlights recent progress in the design and application of bioinspired and engineered biomaterials, including natural, synthetic, and hybrid scaffolds, which mimic the extracellular matrix and guide neural cell behavior. Hydrogels, stimuli-responsive polymers, and conductive nanocomposites are increasingly used in scaffold fabrication and 3D bioprinting. Integration with patient-derived induced pluripotent stem cells (iPSCs) and microfluidic platforms enables the creation of physiologically relevant models that replicate key pathological features. We discuss the importance of quantitative materials characterization including porosity, stiffness, swelling, degradation, and wettability in ensuring scaffold reproducibility and translational relevance. Despite challenges like vascularization and culture stability, innovations are addressing these barriers. Advanced biomaterials enable precise cell placement and structure. High-precision bioprinting and microfluidics support perfusable vessels. AI-driven data integration enhances scalability, optimizes conditions, analyzes large datasets, and improves reproducibility by minimizing batch variability in 3D in vitro models. Recent advances in bioelectric and electrochemical biomaterials including piezoelectric PLLA membranes, wirelessly self-powered Zn/Ag2O scaffolds, 3D-printed carbon nanoelectrodes, and conductive POSS-PCL/graphene nanocomposites offer promising multifunctional platforms for 3D neurodegenerative disease models.
神经退行性疾病,包括阿尔茨海默病(AD)、帕金森病(PD)、亨廷顿病(HD)和肌萎缩侧索硬化症(ALS),由于其进行性和缺乏治愈性治疗,仍然是一个主要的全球健康挑战。传统的动物模型和二维细胞培养不能概括这些疾病的复杂微环境和人类特异性病理生理。因此,结合功能性生物材料的先进3D体外模型已成为复制疾病机制、实现个性化医疗和加速治疗发现的有前途的平台。本文综述了生物启发和工程生物材料的设计和应用方面的最新进展,包括天然、合成和混合支架,它们模拟细胞外基质并指导神经细胞行为。水凝胶、刺激响应聚合物和导电纳米复合材料越来越多地用于支架制造和3D生物打印。与患者衍生的诱导多能干细胞(iPSCs)和微流控平台的整合,可以创建复制关键病理特征的生理相关模型。我们讨论了定量材料表征的重要性,包括孔隙度、刚度、膨胀、降解和润湿性,以确保支架的可重复性和翻译相关性。尽管存在血管化和培养稳定性等挑战,但创新正在解决这些障碍。先进的生物材料可以实现精确的细胞放置和结构。高精度生物打印和微流体支持可灌注血管。人工智能驱动的数据集成增强了可扩展性,优化了条件,分析了大型数据集,并通过最小化3D体外模型的批量变化提高了再现性。生物电和电化学生物材料的最新进展,包括压电PLLA膜、无线自供电Zn/Ag2O支架、3D打印碳纳米电极和导电POSS-PCL/石墨烯纳米复合材料,为3D神经退行性疾病模型提供了有前途的多功能平台。
