During metastasis, cancer cells leave the primary tumor, intravasate into the circulatory or lymphatic system, circulate until they can extravasate, and take up residence in a secondary location of the body to form a metastatic tumor. In order to leave the vasculature during extravasation, circulating tumor cells utilize a highly orchestrated adhesion cascade that begins with rolling adhesion to endothelial cells under a high shear environment. This process is driven by interactions between endothelial-presented selectins and selectin ligands present on the circulating cell\u0026rsquo;s surface. These selectin-selectin ligand interactions have been implicated in cancer metastasis, however, an outstanding problem in the field is the lack of effective systems to study the role of wall shear stress and cellular molecular profiles in initiating and sustaining these interactions, and how this may lead to enhanced metastatic capacity of circulating tumor cells.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EAs such, \u003Cstrong\u003E\u003Cem\u003Ethe\u003C\/em\u003E\u003C\/strong\u003E\u003Cem\u003E \u003Cstrong\u003Eoverall objective\u003C\/strong\u003E \u003C\/em\u003Eof this thesis is to engineer microfluidic platforms to permit the analysis of selectin-mediated adhesion and interrogation of cellular characteristics underlying selectin-selectin ligand interactions between the endothelium and metastatic cell subpopulations that occur during cancer dissemination in a tumor microenvironment.
