Core Component B, the Signaling and Motility Assays Core, will provide the expertise, protocols, analysis and interpretation of in vitro assays that examine the individual behavior, and interaction of tumor and stromal cells. The Core performs assays examining two-dimensional motile cell behavior, three-dimensional invasion, angiogenesis and transendothelial migration. These assays permit a comprehensive examination of cell behavior during chemotaxis, and provide a rapid and complete analysis of the invasive capabilities of a given cell type prior to costly and time-consuming animal studies. Moreover these in vitro assays support and complement the in vivo studies provided by the Intravital Imaging, Invasive Cell Collection and Expression Profiling Core (Core A). Core B will also act as a liaison for the use of unique protein biosensors and for assays examining invadopod formation so that the application of these technologies is uniform amongst the projects. The in vitro assays supported by Core B provide much needed information about cellular behavior and mechanism during tumor cell invasion and intravasation.The leading cause of death in cancer patients is the ability of tumor cells to leave the primary tumor, travel to distant sites within the body and form secondary tumors. The assays provided by this Core specifically examine the individual behavior and interaction of tumor and stromal cells, and will provide the foundation for understanding the mechanisms regulating tumor cell motility and invasion.

核心组件B，即信号传导和运动测定核心，将提供专业知识、方案和分析 和体外分析的解释，检查个体行为，以及肿瘤和 基质细胞Core进行检测二维运动细胞行为、三维运动细胞行为和三维运动细胞行为的分析。 侵袭、血管生成和跨内皮迁移。这些化验允许全面检查 在趋化过程中的细胞行为，并提供了一个快速和完整的分析侵入能力， 在昂贵和耗时的动物研究之前，此外，这些体外测定支持 并补充活体成像、侵入性细胞收集和 表达谱核心（核心A）。核心B还将作为使用独特蛋白质生物传感器的联络人 以及用于检验侵入足形成的测定， 在这些项目中。核心B支持的体外试验提供了以下方面的急需信息： 肿瘤细胞侵袭和内渗过程中的细胞行为和机制。 癌症患者是肿瘤细胞的能力离开原发性肿瘤，旅行到体内的遥远部位 形成继发性肿瘤该核心提供的分析专门检查个体行为 以及肿瘤和基质细胞的相互作用，并将为理解其机制提供基础。 调节肿瘤细胞运动和侵袭。
