Granulosa cells in ovarian follicles of rat, mouse, rabbit and hamster were studied by lanthanum tracer and freeze-fracture techniques. Abundant gap junctions exhibited striking intraspecific variation in size and pattern of particle aggregation. The smaller gap junctions showed close packing of the intramembranous A face particles. In large gap junctions, ranging up to 6 mu in diameter, particles were packed in rectilinear arrays separated by a labyrinthine network of particle-free 'aisles'. Small clusters of particles in a particle-poor circumferential zone suggested enlargement of junctions by peripheral accretion. Linear intramembranous structures, resembling those of occluding junctions, occasionally bounded large gap junctions. Spherical intracytoplasmic structures limited by gap junctional membranes were shown by tracer studies to arise by invagination of the cell surface. These were intrepreted as a means of disposal of junctions by interiorization.
