[Ultrastructural and histochemical study of the zones of the junctions of luteal cells in women. Functional significance].
We are reporting here the results of an electron microscopic study of the junction between cells which have been seen in corpora lutea in human beings between the 20th and 27th days of the cycle. Conventional electron microscopic techniques, using tracers (plotters) for the extracellular spaces as well as Thiery's histochemical technique, were used. Two principal types of junctions between the cells have been described: tight junctions and septate junctions. A discussion takes place about the different histophysiological problems which presented (LH hormone receptors and intercellular diffusion of the message).
