由选择素(由活化的内皮细胞、活化的血小板和白细胞表达)与其各自的选择素配体(由癌细胞表达)结合介导的细胞粘附可能参与转移。因此,表征在人组织上表达的选择素配体的方法可作为有价值的测定。本文提供了一种用于检测在人体组织上表达的功能性选择素配体的创新方法,其使用动态方法,其允许控制施加到探针和靶分子之间的键的力。这种新的组织询问方法,称为动态生化组织分析(DBTA),涉及在组织上灌注分子探针涂层微球。使用选择素包被的探针的DBTA能够检测在原发和转移部位的多种癌症类型的组织上表达的功能性选择素配体。
Cell adhesion mediated by selectins (expressed by activated endothelium, activated platelets, and leukocytes) binding to their resepective selectin ligands (expressed by cancer cells) may be involved in metastasis. Therefore, methods of characterizing selectin ligands expressed on human tissue may serve as valuable assays. Presented herein is an innovative method for detecting functional selectin ligands expressed on human tissue that uses a dynamic approach, which allows for control over the force applied to the bonds between the probe and target molecules. This new method of tissue interrogation, known as dynamic biochemical tissue analysis (DBTA), involves the perfusion of molecular probe-coated microspheres over tissues. DBTA using selectin-coated probes is able to detect functional selectin ligands expressed on tissue from multiple cancer types at both primary and metastatic sites.
