The lumenal surface of these epithelial cells is composed of plaques separated by interplaque regions.  Within the plaques are hexagonal arrays of subunits (about 12nm, with center-to-center spacing of 15.6nm) on the E-face of the membrane.  The inset panel shows these subunits at higher magnification, prepared by deep-etching rather than fracturing after freezing.  At higher magnification, each subunit within the plaque appear to be composed of a ring of six particles surrounding a channel.  These plaques are distinguished from gap junctions (found on the P-face of membranes) by their location on their position instead on the E-face.  These micrographs courtesy of Nicholas Severs and Marian Hicks, Figure 13 from Chapter 1 (The Cell Surface) of 'The Cell, 2nd Ed.' by Don W.
