During cleavage and blastula stages of embryos of the teleost Fundulus heteroclitus all of the cells are both electotonically coupled and dye coupled to one another, as determined by microelectrode impalements and spread of Lucifer Yellow. At about the time that gastrulation begins we observed a specific loss of junctional coupling between the yolk cell and cells of the blastoderm. Passage of Lucifer Yellow between the yolk cell and blastoderm was reduced at stage 12 (late blastula), and not detected at stage 13 and thereafter, although cells of the blastoderm remain dye coupled to one another through gastrula stages. Also, junctional electrical coupling between the yolk cell and blastoderm became substantially reduced at stage 13 and thereafter. The loss of coupling at this specific cell apposition and time and the large size of the yolk cell may prove useful in analyzing the underlying cellular mechanisms.
