Cells in the marginal zone of the spleen. Kraal G(1). Author information: (1)Department of Cell Biology, Free University, Amsterdam, The Netherlands. The marginal zone of the spleen forms an intriguing area in which a variety of cell types are combined.ntigenic fragments produced this way can be taken up by dendritic cells that enter the spleen by the blood as part of a mobile surveillance immune system.
