WebApr 26, 2009 · Morphologically, cancer cells in lymph nodes were described as marginal sinus, intermediate sinus, parenchymal, and diffuse types. Marginal sinus is the most common type. This may be due to migrant cancer cells that were initially arrested in the marginal sinus [14, 17]. In this study, metastatic foci in lymph nodes were mainly located … The major role of marginal zone is to trap particulate antigen from the circulation and present the antigen to the lymphocytes of the spleen. Experiments have shown that inert latex beads as well as live bacteria such as Escherichia coli and Listeria monocytogenes are trapped by the marginal zone. However, only immunogenic substances, i.e. bacteria, are trafficked to the T and B cell zones of the white-pulp and are efficie… WebDec 1, 2007 · Like the marginal sinus of the lymph node, they not only transport lymph, they are a section of the lymphatic system with specific structures and functions.
