摘要
最近的研究展示了一系列来源于干细胞的自组织微型器官,称为类器官,它们复制了其体内对应物的关键结构和功能特征。随着类器官技术为生物医学研究开辟新的前沿,生产、控制和分析类器官及其微环境的创新工程方法的需求日益迫切。在本综述中,我们探讨了器官芯片技术作为满足这一需求的平台,并研究了如何利用这一技术来解决类器官研究中的主要技术挑战。我们还讨论了类器官芯片技术开发和应用中的新机遇及未来障碍。
英文摘要
Recent studies have demonstrated an array of stem cell-derived, self-organizing miniature organs, termed organoids, that replicate the key structural and functional characteristics of their in vivo counterparts. As organoid technology opens up new frontiers of research in biomedicine, there is an emerging need for innovative engineering approaches for the production, control, and analysis of organoids and their microenvironment. In this Review, we explore organ-on-a-chip technology as a platform to fulfill this need and examine how this technology may be leveraged to address major technical challenges in organoid research. We also discuss emerging opportunities and future obstacles for the development and application of organoid-on-a-chip technology.

本研究采用了类器官-芯片技术,通过微流控设备来模拟和控制类器官的微环境。其技术路线可用以下流程图表示:
- 类器官的培养:使用干细胞在三维环境中培养类器官。
- 微流控芯片设计:构建微流控设备以模拟器官的生理特性。
- 环境控制与营养供给:通过微流控系统控制生化梯度和营养供给,确保类器官的生长和发育。
- 组织间相互作用建模:在芯片上实现不同组织的共培养,模拟组织间的相互作用。
- 生物传感器集成:集成传感器以实时监测类器官的功能状态。
- 个性化医疗与药物发现:应用类器官-芯片技术于个性化疾病模型和药物筛选。
关键结果和发现
- 微环境控制:微流控系统能够精确控制类器官的生化环境和营养供给,显著提高了类器官的成熟度和功能性。
- 组织间相互作用:通过多器官模型,成功模拟了肝脏和肠道之间的相互作用,揭示了生理信号的传递机制。
- 减少变异性:采用自动化和高通量技术减少了类器官培养过程中的变异性,提高了实验的重复性和可靠性。
主要结论/意义/创新性
类器官-芯片技术结合了类器官和微流控技术的优势,为生物医学研究提供了一个高效、可控的平台。这一技术不仅有助于提高类器官的生理相关性,还有助于个性化医疗和药物开发,具有广泛的应用前景。
研究局限性和未来方向
尽管类器官-芯片技术展现了巨大潜力,但仍面临一些挑战,包括:
- 动态变化的再现:目前的模型在再现器官发育过程中的动态变化方面仍有限。
- 材料选择:常用的基质材料(如Matrigel)存在批次间差异,影响可重复性。
- 多器官模型的复杂性:建立功能完善的多器官模型仍需进一步研究。
未来的研究方向应集中在优化材料选择、提升模型的动态响应能力以及加强多器官系统的功能集成,以推动类器官-芯片技术在生物医学领域的应用。
