Linear arrays of particles, identical to those in the cup cells of the small intestine, characterize the brush border membrane of a subpopulation of surface epithelial cells in freeze-fracture replicas of the rabbit caecum. Although these cells lack a cup-like indentation of their brush border, we propose that all intestinal epithelial cells showing this arrangement of intramembranous particles in their apical membrane belong to a distinct subpopulation of the epithelial cells. A specific function of this cell type that is related to the linear arrays of particles remains to be determined.
