Oocyte-follicle cell gap junctions in Xenopus laevis and the effects of gonadotropin on their permeability.

Junctions between Xenopus laevis oocytes and follicle cells have been identified as gap junctions by the passage of microinjected fluorescent dye from oocytes to follicle cells. The opening or assembly of these junctions, or both, appears to be regulated by gonadotropins.
