摘要:

文题释义:
肠类器官:是含关键性的肠细胞类型,包括肠上皮细胞、杯状细胞、肠内分泌细胞和肠干细胞,再现了肠上皮的生理结构,位于肠类器官内的活跃分裂的干细胞群保证这些类器官的长期稳定扩增和传代。
胰腺类器官:来源于从胰腺导管中分离出的胰腺干/祖细胞的扩增,在添加有适当的生长因子和细胞外基质的培养环境中,胰腺祖细胞形成胰腺外分泌类器官。

背景:类器官模型可部分还原细胞在体内的组织和分子特性,是一种有良好潜力的临床前模型。与传统精准、再生医学手段相比,类器官能最大程度模拟体内器官,具有组织器官功能;类器官药物敏感性数据较全基因组测序更加准确;能与体外基因编辑技术结合,实现器官水平上的基因改造。
目的:总结和分析近10年国内外数据库类器官模型文献的研究热点。
方法:计算机检索万方、Web of Science、中国临床试验注册中心、北美临床试验注册中心及SooPAT中国专利数据库与类器官相关的近10年文献,对类器官模型文献的研究热点进行分析总结。
结果与结论:①万方数据库检索结果:纳入187篇文献,2019年类器官中文研究呈爆发式增长,其中肠类器官模型研究较多,主要应用领域包括精准医疗、肿瘤研究和个体化医疗;②Web of Science数据库(核心集)检索结果:共纳入2 450篇文献,采用Histcite软件分析20篇高被引文章筛选出5条类器官原始经典文献,分别介绍了肠道类器官、多能干细胞衍生的三维大脑类器官、从活检标本和循环肿瘤细胞中长期培养的前列腺癌类器官、含有肾单位的肾类器官及人胃组织三维类器官模型的构建方法,均分别为各领域的开山之作,为类器官后续研究打下了基础;③临床注册信息检索结果:检索到与类器官研究有关的中国临床注册方案13篇,北美临床注册方案23篇,美国类器官临床研究领域更广泛,开展时间更早,但多为队列研究和单臂试验,而中国近年来在类器官临床研究领域已经取得了一些成果,有2个受人瞩目的随机对照试验方案正在进行中;④SooPAT中国专利数据库检索结果:共检索到55项有权专利,主要专利技术涉及3D大脑类器官新型培养方法,高通量3D细胞、类组织及类器官动态培养系统的研发等;⑤上述数据说明,目前研究者已经能够成功构建出多种模拟人体器官功能的类器官体外模型(如肠、脑、肾及各种癌组织),但由于缺乏足够的临床随机对照试验证据,因此临床适用性还有待探讨,而利用癌症患者的肿瘤组织直接培养生成体外肿瘤类器官,分析潜在的药物治疗靶点,进行抗癌药物筛选及开发抗肿瘤新药,将是未来类器官领域主要研究方向。

Abstract: BACKGROUND: Organoid models can partially restore the tissue and molecular characteristics of cells in the body, which is a preclinical model with good potential. Compared with precise and regenerative medicine methods, organoids with tissue organ functions can simulate body organs to the greatest extent. Moreover, organoid drug sensitivity data is more accurate than whole-genome sequencing. The technology for organoids can be combined with in vitro gene editing technology to achieve a genetic modification at organ level.   
OBJECTIVE: To summarize and analyze the research hotpots of organoid models in domestic and foreign databases in the past 10 years. 
METHODS: A computer search of WanFang, Web of Science, Chinese Clinical Trial Registry, ClinicalTrials.org and SooPAT was performed for articles regarding organoids in the past 10 years, and the research hotspots of organoid models were analyzed and concluded.  
RESULTS AND CONCLUSION: (1) Retrieval results of WanFang database: A total of 187 articles were included. In 2019, Chinese research on organoids showed an explosive growth. Among them, there were more studies on intestinal organoid models. The main application areas included precision medicine, tumor research and personalized medicine. (2) Retrieval results of the Web of Science Core Collection: A total of 2 450 articles were included. Twenty highly cited articles were analyzed using Histcite software. Among them, five classic original articles of organoids were screened out, and introduced intestinal organoids, pluripotent stem cell-derived three-dimensional brain organoids, prostate cancer organoids cultured from biopsy specimens and circulating tumor cells for a long time, kidney organoids containing nephrons, and three-dimensional organoid models of human stomach tissue, which are the pioneers in various fields and lay the foundation for future research on organoids. (3) Retrieval results of Chinese Clinical Trial Registry and ClinicalTrials.org: There were 13 study protocols related to organoid research in the Chinese Clinical Trial Registry and 23 in the ClinicalTrials.org. Research on clinical application of organoids in the United States is more extensive and develops earlier, but there are mostly cohort studies and single-arm trials. In recent years, China has achieved some results in the field of clinical organoid research, and two high-profile randomized controlled trials are underway. (4) Retrieval results of SooPAT Chinese patent database: There were 55 authorized patents, mainly involving the new culture method of 3D brain organoids, the research and development of high-throughput 3D cell, tissue-like and organoid dynamic culture systems. At present, researchers have successfully constructed a variety of organoid models, such as intestine, brain, kidney and various cancer tissues. However, due to insufficient evidence of clinical randomized controlled trials, the clinical applicability remains to be explored. Tumor organoids that are directly generated by tumor tissues of cancer patients in vitro can be used to analyze potential drug targets, screen anti-cancer drugs and develop new anti-tumor drugs, which will be the main research directions in the field of organoids in the future.
