Cancer cells interacting with the extracellular matrix (ECM) in the tumor microenvironment is pivotal for tumorigenesis, invasion, and metastasis. Cell-ECM adhesion has been intensively studied in cancer biology in the past decades to understand the molecular mechanisms underlying the adhesion events and extracellular mechanosensing, as well as develop therapeutic strategies targeting the cell adhesion molecules. Many methods have been established to measure the cell-ECM adhesion strength and correlate it with the metastatic potential of certain cancer types. However, those approaches are either low throughput, not quantitative, or with poor sensitivity and reproducibility. Herein, we developed a novel acoustic force spectroscopy based method to quantify the cell-ECM adhesion strength during adhesion maturation process using the emerging z-Movi technology. This can be served as a fast, simple, and high-throughput platform for functional assessment of cell adhesion molecules in a highly predictive and reproducible manner.
癌细胞与肿瘤微环境中的细胞外基质(ECM)相互作用对于肿瘤发生、侵袭和转移至关重要。在过去几十年的癌症生物学研究中,细胞-ECM 黏附一直是研究热点,目的是为了深入了解黏附事件和细胞外机械感受的分子机制,并开发针对细胞黏附分子的治疗策略。已经建立了许多方法来测量细胞-ECM 黏附强度,并将其与某些癌症类型的转移潜力相关联。然而,这些方法要么通量低,要么不是定量的,要么灵敏度和重现性差。在这里,我们使用新兴的 z-Movi 技术开发了一种基于声力量子技术的新方法,用于在黏附成熟过程中定量测量细胞-ECM 黏附强度。这可以作为一种快速、简单和高通量的平台,以高度可预测和可重复的方式对细胞黏附分子进行功能评估。
