中文摘要
背景:生物融合将材料科学、微电子学与类器官生物学相结合,以革新器官芯片(OOC)技术,促进有效的转化药物发现。我们的项目旨在通过将人源3D细胞培养物与基于半导体、集成传感器的微流控硅芯片相整合,开发新一代体外平台,从而实现对相互连接的多器官生理机能的模拟。
方法:我们从诱导多能干细胞(iPSC)和患者来源类器官(PDO)培育出人源肠道和肝脏类器官。通过对关键标志物的免疫荧光、针对基因面板的RT-qPCR,以及跨上皮电阻(TEER)和酶活性等功能性检测,验证了类器官的谱系身份和功能。这一经过验证的生物学系统在无菌条件下通过连接流体和电学接口实现整合。
结果:十二指肠PDO来源的肠道类器官表现出明确的上皮结构和屏障完整性,并表达关键转运体(BCRP)和代谢酶(CYP3A4、UGT1A1)。它们还表达谱系标志物,包括刷状缘(Villin)、杯状细胞(MUC2)、潘氏细胞(LYZ)和肠内分泌细胞(CHGA)。iPSC来源的成熟肝脏类器官表达肝细胞和胆管细胞标志物,包括albumin、Sox9、CK7和CK19,展现出I/II相代谢能力以及相关药物转运体(CYP3A4、GST、MDR1/P-gp、MRP2)。这些类器官系统为探索该平台的可行性和功能奠定了坚实基础。
结论:将经过验证的人源类器官生物学与可扩展的半导体微流控技术相整合,创建出一种微生理平台,可显著提升在毒理学、药物代谢与药代动力学(DMPK)以及疾病建模方面的转化相关性。它支持开发更安全、更有效的治疗方法,同时最大限度减少对动物实验的依赖。

Background: Bioconvergence combines materials science, microelectronics with organoid biology to revolutionize organ-on-a-chip (OOC) technology, facilitating effective translational drug discovery. Our initiative aims to develop new generation of in vitro platforms by integrating human 3D cell cultures with a semiconductor-based, sensor-integrated microfluidic silicon chip, enabling the simulation of interconnected multi-organ physiology.
Methods: We developed human gut and liver organoids from induced pluripotent stem cells (iPSCs) and patient-derived organoid (PDO). The organoids were validated for lineage identity and functionality through immunofluorescence for key markers, RT-qPCR for gene panels, and functional assays such as transepithelial electrical resistance (TEER) and enzyme activity. This validated biology was integrated by connecting it to fluidic and electrical interfaces in sterile conditions.
Results: Duodenal PDO-derived gut organoids exhibited well-defined epithelial architecture and barrier integrity, along with the expression of essential transporters (BCRP) and metabolic enzymes (CYP3A4, UGT1A1). They also displayed lineage markers, including brush border (Villin), goblet (MUC2), Paneth (LYZ), and enteroendocrine (CHGA) cells. iPSC-derived mature liver organoids expressed markers for hepatocytes and cholangiocytes, including albumin, Sox9, CK7, and CK19, demonstrating Phase I/II metabolic competence and relevant drug transporters (CYP3A4, GST, MDR1/P-gp, MRP2). These organoid systems establish a solid foundation for exploring the viability and functionality of the platform.
Conclusions: Integrating validated human organoid biology with scalable semiconductor microfluidics creates a microphysiological platform that significantly enhances translational relevance for toxicology, drug metabolism and pharmacokinetics (DMPK), and disease modeling. It supports the development of safer, more effective therapies while minimizing reliance on animal studies.
