WebNov 1, 1989 · The marginal cells form a continuous layer along the lumenal surface (facing the endolymph in scala media) and are of epithelial origin. The basal cells also form a continuous layer, next to the spiral ligament and cochlear wall, and the origin of these cells is not known: they may be either mesodermal or derived from the neural crest. 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…
