Abstract
Reaggregated cells from Xenopus laevis embryos in blastula through larval stages become electrically coupled within 20 min of the beginning of aggregation. Some of these cells can exchange fluorescein injected intracellularly. The transfer of dye appears to depend on the presence of low-resistance junctions although the precise site of transfer is unknown. The relevance of these results to processes occurring in intact embryos is discussed.
