The invasion and migration abilities of tumor cells are main contributors to cancer progression and recurrence. Many studies have explored the migration and invasion abilities to understand how cancer cells disseminate, with the aim of developing new treatment strategies. Analysis of the cellular and molecular basis of these abilities has led to the characterization of cell mobility and the physicochemical properties of the cytoskeleton and cellular microenvironment. For many years, the Boyden chamber assay and the scratch wound assay have been the standard techniques to study cell invasion and migration. However, these two techniques have limitations. The Boyden chamber assay is difficult and time consuming, and the scratch wound assay has low reproducibility. Development of modern technologies, especially in microscopy, has increased the reproducibility of the scratch wound assay. Using powerful analysis systems, an "in-incubator" video microscope can be used to provide automatic and real-time analysis of cell migration and invasion. The aim of this paper is to report and compare the two assays used to study cell invasion and migration: the Boyden chamber assay and an optimized in vitro video microscope-based scratch wound assay.
肿瘤细胞的侵袭和迁移能力是癌症进展和复发的主要因素。许多研究探讨了迁移和侵袭能力,以了解癌细胞如何扩散,目的是开发新的治疗策略。对这些能力的细胞和分子基础的分析导致了细胞迁移性以及细胞骨架和细胞微环境的物理化学性质的表征。多年来,Boyden小室试验和划痕试验一直是研究细胞侵袭和迁移的标准技术。然而,这两种技术都有局限性。Boyden小室试验困难且耗时,划痕试验的可重复性较低。现代技术的发展,尤其是显微镜技术的发展,提高了划痕试验的可重复性。使用强大的分析系统,“培养箱内”视频显微镜可用于对细胞迁移和侵袭进行自动实时分析。本文的目的是报告和比较用于研究细胞侵袭和迁移的两种试验:Boyden小室试验和基于体外视频显微镜的优化划痕试验。
