Abstract
Ajacent processes on ovarian decidual cells were shown by electron microscopy to form gap junctions with one another. Micrographs of tissues preserved with lanthanum included in the fixative confirm the hexagonal array and 2-4 nm gap which characterize gap junctions. It is suggested that these gap junctions may play a role in the process of merocrine secretion from the peduncular processes of ovarian decidual cells. The term reflexive gap junction is introduced to describe gap junctions between adjacent processes from the same cell.
