稀有细胞可能很难分析,因为它们要么数量很少,要么与更丰富的细胞类型共存,但它们的检测对于诊断疾病和维护人类健康至关重要。在本教程中,我们介绍了微流体随机限制的概念,用于检测和分析稀有细胞。随机限制提供了两个优点:1)它将稀有的单细胞与本体混合物分离,以及2)它允许信号在单个细胞周围局部积累到比本体混合物中更高的浓度。微流体是一种有吸引力的方法,用于实现随机约束,因为它提供了简单的处理小体积。我们提出了微流体随机约束技术,利用威尔斯和液滴的检测和分析的单细胞。我们将讨论这些微流体技术如何用于观察新的行为,提高检测速度,并增强稀有细胞的培养。我们讨论了微流控随机限制在人类诊断和环境测试等领域的潜在应用。
Rare cells can be difficult to analyze because they either occur in low numbers or coexist with a more abundant cell type, yet their detection is crucial for diagnosing disease and maintaining human health. In this tutorial review, we introduce the concept of microfluidic stochastic confinement for use in detection and analysis of rare cells. Stochastic confinement provides two advantages: 1) it separates rare single cells from the bulk mixture and 2) it allows signals to locally accumulate to a higher concentration around a single cell than in the bulk mixture. Microfluidics is an attractive method for implementing stochastic confinement because it provides simple handling of small volumes. We present technologies for microfluidic stochastic confinement that utilize both wells and droplets for the detection and analysis of single cells. We address how these microfluidic technologies have be used to observe new behavior, increase speed of detection, and enhance cultivation of rare cells. We discuss potential applications of microfluidic stochastic confinement to fields such as human diagnostics and environmental testing.
