Systems biology seeks to develop a complete understanding of cellular mechanisms by studying the functions of intra- and inter-cellular molecular interactions that trigger and coordinate cellular events. However, the complexity of biological systems causes accurate and precise systems biology experimentation to be a difficult task. Most biological experimentation focuses on highly detailed investigation of a single signaling mechanism, which lacks the throughput necessary to reconstruct the entirety of the biological system, while high-throughput testing often lacks the fidelity and detail necessary to fully comprehend the mechanisms of signal propagation. Systems biology experimentation, however, can benefit greatly from the progress in the development of microfluidic devices. Microfluidics provides the opportunity to study cells effectively on both a single- and multi-cellular level with high-resolution and localized application of experimental conditions with biomimetic physiological conditions. Additionally, the ability to massively array devices on a chip opens the door for high-throughput, high fidelity experimentation to aid in accurate and precise unraveling of the intertwined signaling systems that compose the inner workings of the cell.
系统生物学试图通过研究触发和协调细胞事件的细胞内和细胞间分子相互作用的功能,来全面理解细胞机制。然而,生物系统的复杂性使得准确而精确的系统生物学实验成为一项艰巨的任务。大多数生物学实验专注于对单一信号传导机制进行高度详细的研究,这缺乏重建整个生物系统所需的通量,而高通量测试往往缺乏全面理解信号传播机制所需的保真度和细节。然而,系统生物学实验可以从微流控设备的发展进步中受益匪浅。微流控技术提供了在单细胞和多细胞水平上有效研究细胞的机会,能够以高分辨率并在仿生生理条件下局部应用实验条件。此外,在芯片上大规模阵列设备的能力为高通量、高保真实验打开了大门,有助于准确而精确地解开构成细胞内部运作的相互交织的信号系统。
