肿瘤微环境是由多种细胞类型和物理特征组成的复杂异质组装体。其中一个特征,缺氧,与代谢重编程、上皮-间质转化和治疗抗性相关。关于缺氧对这些结果的影响仍然存在许多问题,但只有少数实验方法能够精确控制氧浓度和实时成像细胞行为。最近对微流体平台的努力为这些限制提供了有希望的解决方案。我们讨论了用于控制细胞研究中氧浓度的常规方法和工具,然后强调了在工程平台中控制氧的基于微流体的方法的最新进展。
The tumor microenvironment is a complex heterogeneous assembly composed of a variety of cell types and physical features. One such feature, hypoxia, is associated with metabolic reprogramming, the epithelial-mesenchymal transition, and therapeutic resistance. Many questions remain regarding the effects of hypoxia on these outcomes, yet only few experimental methods enable both precise control over oxygen concentration and real-time imaging of cell behavior. Recent efforts with microfluidic platforms offer a promising solution to these limitations. We discuss conventional methods and tools used to control oxygen concentration for cell studies then highlight recent advances in microfluidic-based approaches for controlling oxygen in engineered platforms.
