In the teleost P. altivelis, intercellular junctions between microvilli of an oocyte and follicle cells were studied by EM. Microvilli, which were radiated from an oocyte and arrived at the surface of follicle cells, established contact with follicle cells. These contact areas appeared to be a 7-layered membrane with an overall thickness of .apprx. 18 .mu.m by standard fixation. In freeze-fracture replicas, many small aggregates of intramembranous particles were revealed on the cleavage faces of cytoplasmic membranes of follicle cells. In the teleost gap, junctions evidently exist between the oocyte and follicle cells, especially on the surface of follicle cells.
